Book excerpt: U.S. troops face increasing risk of exposure to chemical and biological warfare threats as poorer nations and terrorist groups turn to these lower cost weapons for their arsenals. Despite the increased menace from these lethal agents, gas mask technology has remained virtually unchanged over the past several decades thus leaving soldiers at risk to newly developed nerve and pathogenic agents designed to defeat conventional GAC gas mask technology. EKOS Materials Corp. proposes a novel activated carbon fiber (ACF) that will combine the low cost and durability of GAC with tailored pore size and pore surface chemistry for improved defense against chemical weapons. One of the key advantages of this ACF is that it can be manufactured in a wide variety of product forms (textiles, felts, papers) which allows for vast design flexibility. Thus the potential exists to utilize carbon coated sub-micron glass fibers to replace both components of the current gas mask (HEPA filter and GAC) to greatly reduce pressure drop and achieve filtration/adsorption in a single step.

Book excerpt: U.S. troops and civilians face increasing risk of exposure to chemical and biological threats as developing nations and terrorist groups turn to these lower cost weapons for their arsenals. EKOS has developed a novel activated carbon fiber - (ACF) that combines the low cost and durability of GAC with tailored pore size and pore surface chemistry for improved defense against chemical agents. ACF has another key advantage as it can be manufactured in a wide variety of product forms that allows for design flexibility (hoods, masks, parkas, handkerchiefs). In addition, EKOS demonstrated the potential to utilize carbon coated sub-micron glass fibers to replace both components of the current gas mask (HEPA filter and bed of GAC) to greatly reduce pressure drop and achieve filtration/adsorption in a single step. Finally, designed structures obtained through computational fluid dynamics were built through stereolithography (honeycomb and octet truss) then coated with activated carbon to examine a unique strategy for next generation gas masks.

This book was released on 2020-06-27 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The deterioration of water quality and unavailability of drinkable water are pressing challenges worldwide. The removal of toxic organic and inorganic pollutants from water is vital for a clean environment, as a response to water scarcity. Adsorption-based water technologies are among the most widely used because of their high efficiency and low cost, without relying on a complex infrastructure. In recent years, carbon nanomaterials (CNMs), such as graphene and derivatives, carbon nanotubes, carbon nanofibers, nanoporous carbon, fullerenes, graphitic carbon nitride, and nanodiamonds have been extensively exploited as adsorbents due to their extraordinary surface properties, ease of modification, large surface area, controlled structural varieties, high chemical stability, porosity, low density, ease of regeneration, and reusability. This book provides a thorough overview of the state of the art in carbon nanomaterials as they are used for adsorption applications in water purifications, as well as addressing their toxicological challenges. This volume primarily explores the fundamentals of adsorption, its mechanical aspects, synthesis and properties of CNMs, and adsorption performances of CNMs and their nanocomposites with organic and inorganic materials. Structural engineering and activation processes produce materials with enhanced adsorptive properties and separation efficiencies. Furthermore, the formation of CNMs with 2D and 3D macro-and microstructures and high porosities is a potential approach to improve adsorption performances and extend CNM use at the industrial level. The book also addresses important issues regarding these adsorbents that potentially affect future research and industrial applications of carbon-based nanoadsorbents in water security. - Presents advances in multifunctional 3D superstructures of carbon nanomaterials and their composites for adsorption applications - Outlines the fundamentals on synthesis and characterization techniques of carbon-based nanostructures and their composites - Assesses the major toxicological challenges in using nanostructured materials as adsorbents for water purification

Available in PDF, EPUB and Kindle. Book excerpt: "Phenols are classified to be one of the most hazardous pollutants found in wastewater. They are discharged into rivers, lakes and seas, causing adverse effects on the environmental and human health. Adsorption is a well-known technique used to treat wastewater. Activated carbon fibers (ACFs) are highly microporous efficient adsorbents due to their small diameters, high surface area and excellent volumetric capacity. In this work, ACFs were produced using polyacrylonitrile (PAN) fibers using different methods and tools. The fibers were stabilized initially at 250 °C followed by carbonization at 850°C at a heating rate of 10°C/min and under the flow of nitrogen gas at a flow rate of 135ml/min. The carbonized fibers were subjected to physical (carbon dioxide) and chemical (potassium hydroxide) activation. The results showed that chemical activation using 3:1 ratio of KOH(wt/wt) produced fibers with a higher surface area of 2885m2/g compared to the physically activated fibers (774m2/g). The synthesized ACFs (Syn-ACFs) were compared and characterized in terms of morphology, thermal stability, composition and pore characteristics using SEM, EDS, TGA, CHN and nitrogen isotherm (Quantachrome). Bench scale batch experiments were carried out to determine and compare the adsorption efficiency, optimum parameters and the capacity of Syn-ACF and commercial ACFs (C-ACFs) for p-cresol removal. The adsorption optimum conditions using Syn-ACFs are: Syn-ACFs dosage = 1 g/l, contact time = 30 minutes, temperature = 25°C and initial pH = 4.6. The adsorption study on (Syn-ACFs) gave a higher removal efficiency of 91.0% of p-cresol compared to 71.6% (C-ACFs) at a concentration of 350ppm. In addition, the adsorption isotherms of p-cresol on C-ACFs and Syn-ACFs were found to follow the Langmuir isotherm equation; however, Syn-ACFs revealed a higher adsorption capacity (500mg/g) compared to C-ACFs (294 mg/g) at 25°C.The Syn-ACFs regeneration method was evaluated thermally at elevated temperatures and chemically using ethanol and n-hexane solvents. The thermal regeneration at 600°C achieved a higher removal efficiency of 84% compared to n-hexane (78%). The Syn-ACFs were evaluated for the treatment of produced water to ensure a removal of 71.2%. The results indicated that Syn-ACFs could be used as an efficient adsorbent for p-cresol removal in wastewater."--Abstract.
