Download or read book Applications of Chemically Modified Nitrogen Doped Carbon, Zirconium Phosphate, Metal Organic Frameworks, and Functionalized Graphene Oxide Nanostructured Adsorbents in Water Treatment written by Ayyob Mohammed A. Bakry and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Water contaminations by many pollutants, especially heavy metals such as Pb(II), Hg(II), Cu(II), Cd(II), and Cr(VI) pose many public health and environmental concerns as reported in the list of hazardous substances compiled by the US Environmental Protection Agency due to their high toxicity, refractory degradation, and ease of entering food chain. Adsorption by chelating resins is proven to be the most effective method for the extraction of metal ions from polluted and wastewater. However, traditional absorbents such as activated carbon, activated alumina, clay, zeolite, etc., show limited adsorption abilities for these heavy metal ions. The major goal of this thesis is to develop efficient and cost-effective adsorbents for the extraction of heavy metals from wastewater. This dissertation will focus on the development of four chemically modified high surface area adsorbents with accessible chelating sites for capturing and retaining toxic metal ions from polluted water. The first adsorbent, Nitrogen Doped Carboxylated Activated Carbon (ND-CAC), is prepared by a polymerization reaction between melamine and formaldehyde to form the melamine formaldehyde resin (MF-R) followed by carbonization at 800 ̊ C under nitrogen atmosphere to form nitrogen doped carbon (ND-C), and finally oxidation to form the ND-CAC adsorbent. The ND-CAC adsorbent shows high adsorption capacities of 750.5, 250.5, 98.2 mg/g for the extraction of Pb(II), Hg(II), and Cr(VI), respectively from aqueous solutions with a high selectivity to Pb(II). The second adsorbent, Melamine Zirconium Phosphate (M-ZrP) is prepared by a precipitation reaction between Melamine Phosphate (MP) and ZrCl4 in an aqueous solution. The M-ZrP adsorbent is used for the removal of Pb(II), Hg(II), and Cd(II) with maximum adsorption capacities of 680.4, 119.0, and 60.0 mg/g, respectively with a high selectivity to Pb(II). The third adsorbent is chemically functionalized metal organic framework (UIO-66-IT) was prepared by post-synthetic modification using the chelating ligand 2-Imino-4-Thioburit. The adsorbent was used to extract Hg(II) and (HPO4)− ions from aqueous solutions and the results revealed exceptionally high adsorption capacities toward mercury and phosphate ions of 700 and 160 mg/g, placing it among the top functionalized MOF known for the high capacity of Hg(II) removal from aqueous solutions. The fourth adsorbent, Melamine Thiourea Partially Reduced Graphene Oxide (MT-PRGO) prepared by the amidation reaction between chemically modified graphene oxide and melamine thiourea, is used for the effective extraction of Hg(II), Co(II) and Cu(II) from polluted water. The MT-PRGO adsorbent shows exceptional selectivity for the extraction of Hg(II) with a capacity of 651 mg/g, placing it among the top of carbon-based materials known for the high capacity of Hg(II) removal from aqueous solutions. Desorption studies demonstrate that the new adsorbents ND-CAC, M-ZrP, UIO-66-IT, and MT-PRGO are easily regenerated with the desorption of the heavy metal ions Hg(II), Pb(II), Cd(II), and Cr(VI) reaching 99 % - 100 % recovery from their maximum sorption capacities using different eluents. Moreover, all prepared adsorbents showed tremendous abilities to clean contaminated water from toxic heavy metals at trace concentrations. That prove the ability of using them at water contamination level when the concentration of heavy metals is very low. The new adsorbents ND-CAC, M-ZrP, UIO-66-IT, and MT-PRGO are proposed as top performing remediation adsorbents for the extraction of the heavy metals Pb(II), Hg(II), Cd(II), Cr(VI), and (HPO4)− from waste and polluted water.

Book Synopsis From Design to Application by : Jinfeng Zhang
Download or read book From Design to Application written by Jinfeng Zhang and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-organic frameworks (MOFs) are a series of porous materials made of wellorganized inorganic metal nodes linked via organic ligands (linkers). MOFs have gained particular attention due to their applications in gas adsorption and separation, selective sorption of harmful chemicals, catalysis, energy, sensing, bioscience, and electronics. The thesis will focus on two different aspects of MOFs. Briefly, in the first portion of the thesis, a less-toxic solvent than N,N-dimethylformamide (DMF) can be used to make MOFs will be demonstrated. In the latter portion of the thesis, my efforts to incorporate organic moieties into MOFs for sulfur dioxide sequestration will be described. With regard to the use of less-toxic solvents, it should be noted that with notable exceptions (e.g., mechanochemical, water-based, and electrochemical), the synthesis of MOFs is often carried out at elevated temperature using DMF or N,Ndiethylformamide (DEF) as the solvent. However, the industrial-scale synthesis of MOFs from DMF/DEF may generate significant amounts of DMF waste, which can exhibit reprotoxicity and end-of-life issues associated with the formation of NOx upon incineration. With the introduction of the Registration, Evaluation and Authorization of Chemicals (REACH) legislation in the European Union, there is a growing trend towards safer production and use of chemicals by industry. As such, it is crucial to develop green/sustainable methods of synthesizing MOFs. Dihydrolevoglucosenone (Cyrene), a green bioderived solvent from waste cellulose, was applied to the synthesis of MOFs. The MOF, HKUST-1, exhibited a larger Brunauer-Emmett-Teller (BET) surface area than HKUST-1 synthesized with DMF. Four additional archetypal MOFs were also synthesized to verify the universal application of Cyrene in the synthesis of MOFs. However, their BET surface areas were lower than DMF-made MOFs. It was observed that an aldol-condensation product of two Cyrene molecules, in addition to Cyrene trapped within the pores, were responsible for the lower-than expected surface areas. The use of Cyrene has led to a series of design principles that eliminate the need for problematic solvents such as DMF and can be applied to the synthesis of a wide range of MOFs. With regard to sulfur dioxide sequestration, it should be noted that sulfur dioxide, a colorless gas belonging to SOx family, yields detrimental effects via inhalation or absorption. Since MOFs are ideal sorbents for toxic gases, in Chapter 3, I will continue along the theme of reprotoxicity and end-of-life issues by designing MOFs which have the potential to chemically react with sulfur dioxide. Unlike the de novo synthetic pathways in the Chapter 2, the Chapter 3 will demonstrate how solvent-assisted linker exchange (SALE) and solvent-assisted linker incorporation (SALI) can be used to make MOFs with the ideal functionalities for sulfur dioxide sequestration. In Chapter 3, the main focus of the work was to introduce the butadiene functional groups into different MOFs, namely UiO-66, UiO-66-MA (muconic-acid-functionalized UiO-66), MOF-808, MOF-808-BS (butadiene-sulfone-functionalized MOF-808) and MOF-808-BD (butadiene-functionalized MOF-808), the SALI method was vitalized to determine if the butadiene group could undergo a cheletropic reaction in the presence of sulfur dioxide inside the MOF. All MOFs were exposed to a constant flow of sulfur dioxide, the UiO-66-MA was observed to take up three times more sulfur dioxide than the unfunctionalized parent UiO-66. For the MOF-808 series, surprisingly, the unfuctionalized MOF-808 was able to absorb more than two times the sulfur dioxide than MOF-808-BD, and five times higher than MOF-808-BS, respectively. This suggests that the terminal waters and hydroxide groups are responsible for the enhanced uptake. Despite the improved uptake of sulfur dioxide in UiO-66-MA and MOF-808, nuclear magnetic resonance (NMR) and infrared (IR) data indicate that no chemical change occurred to the butadiene-functionalized group, which suggests that a cheletropic reaction did not occur.

Available in PDF, EPUB and Kindle. Book excerpt: Clean and pure water is one of the implicit requisites for a healthy human population. However the growing industrialization and extensive use of chemicals for various concerns, has increased the burden of unwanted pollutants in the drinking water of developing countries like India. The entry of potentially hazardous substances into the biota has been magnifying day by day. In the absence of a possible stoppage of these, otherwise, useful chemicals, the only way to maintain safer water bodies is to develop efficient purifying technologies. One such immensely beneficial procedure that has been in use is that of purification of water using 'adsorbents'. Indigenous minerals and natural plants products have potential for removing many pollutants viz. fluoride, arsenic, nitrate, heavy metals, pesticides as well as tri-halomethanes. Adsorbents which are derived from carbon, alumina, zeolite, clay minerals, iron ores, industrial by products, and natural products viz. parts of the plants, herbs and algal biomass offer promising potential of removal of these pollutants with greater adsorbing efficiencies.
