Book excerpt: Heavy metals are a recognized toxic environmental contaminant, even at very low concentrations. There have been well-known events in the last decade within the US of high amounts of lead in the drinking water supplies of cities, leading to detrimental effects within its population. Ways have been found to remove this metal, and others, from water with expensive adsorbents. The aim of the first part of this research was to create an inexpensive adsorbent from a waste material and modify it in such a way that it would be adept at removing heavy metals from water. In Chapter I, we were able to remove lead, copper, and cadmium using our peanut shell-based activated carbon, getting a high amount of metal adsorption when the activated carbon was activated with phosphoric acid, pyrolyzed, and then cooled under a nitrogen atmosphere. The activated carbon was characterized and found to have a BET surface area of 781 m2g-1 and a Langmuir maximum isotherm capacity of 100.2 mg/g. By using the data obtained in this work, it could lead to the development of further economically made adsorbents to be used to provide more people with clean drinking water. The second part of our work focused on the benefit of a hands-on approach to chemical education. In Chapter IV, we discuss the development and implementation of our NSF-funded summer research experience for undergraduates program, as well as the student-reported results from their 10-week research experience. These surveys showed consistent self-reported growth among the student cohort in the skill sets that were focused on during the program. Chapter V focuses on the development, application, and analysis of results for a novel home-based laboratory component for a semester-long organic chemistry course. It featured 12 lab activities: 8 hands-on experiments and 4 online modeling exercises. By developing and sharing this off-campus approach, we hope to provide an option for other universities that are looking for at-home laboratory experiences for their own students. Overall, we found that these approaches to experiencing chemistry in a hands-on way were beneficial to students and provided them with a greater interest in chemistry.

Download or read book The Characteristic of Palm Shell Based Activated Carbon written by Wan Mohd Ashri Wan Daud and published by . This book was released on 1998 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The char carbonized at 500, 800 and 900 C were prepared to study the effect of char carbonization temperature on activated carbon properties (surface area). Activation process was carried out at various burn off at temperature 820 C in order to investigate the relationship between burn off, surface area and char carbonization temperature. It was found, under the same burn off, the products derived from high carbonization temperature char have higher surface area development and the optimum burn off for absolute surface area is about 40 %.

Book Synopsis Biomass for Sustainable Applications by : Sarra Gaspard
Download or read book Biomass for Sustainable Applications written by Sarra Gaspard and published by Royal Society of Chemistry. This book was released on 2013-12-05 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable sources of energy and a supply of good quality water are two major challenges facing modern societies across the globe. Biomass from cultivated plants may be used to generate energy, but at the cost of contaminated surface waters from pesticide and fertiliser use. This two-volume set examines the potential use of biomass as both a source of sustainable energy and a resource to tackle contaminated soils and wastewaters. Consideration is given to non-food crops, bacteria ,and fungi as sources of biomass and the book enables the reader to identify the best local bioresources according to the desired application. With contributions from across the globe, this is an essential guide to meeting the demand for energy and pollution remediation by exploiting local and renewable resources. The example scenarios given may inspire policy makers and local officers, while chemical engineers and environmental scientists in both academia and industry will benefit from the comprehensive review of current thinking and application.

Book Synopsis Fluoride Removal from Groundwater by Adsorption Technology by : Abdulai Salifu
Download or read book Fluoride Removal from Groundwater by Adsorption Technology written by Abdulai Salifu and published by CRC Press. This book was released on 2018-09-27 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Eastern corridor of Northern region of Ghana, presence of high fluoride concentration in the groundwater has made many drilled boreholes unusable for drinking. Little is, however, known about the factors contributing to the occurrence of high fluoride in this part of Ghana and it's spatial distribution. Treatment of the fluoride-contaminated groundwater by adsorption is also hampered by the lack of suitable adsorbents that are locally available. Based on principal component analysis, and saturation indices calculations, this thesis highlights that, the predominant mechanisms controlling the fluoride enrichment probably include calcite precipitation and Na/Ca exchange processes, both of which deplete Ca from the groundwater, and promote the dissolution of fluorite. The mechanisms also include F-/OH-anion exchange processes, as well as evapotranspiration processes which concentrate the fluoride ions, hence increasing its concentration in the groundwater. Spatial mapping showed that the high fluoride groundwaters occur predominantly in the Saboba, Cheriponi and Yendi districts. The thesis further highlights that, modifying the surface of indigenous materials by an aluminium coating process, is a very promising approach to develop a suitable fluoride adsorbent. Aluminum oxide coated media reduced fluoride in water from 5. 0 ± 0.2 mg/L to ≤ 1.5 mg/L (which is the WHO health based guideline for fluoride), in both batch and continuous flow column experiments in the laboratory. Kinetic and isotherm studies, thermodynamic calculations, as well as analytical results from Fourier Transform Infrared Spectroscopy and Raman spectroscopy, suggest the mechanism of fluoride adsorption onto aluminium oxide coated media involved both physisorption and chemisorption processes. Field testing in a fluoritic community in Northern Ghana showed that the adsorbent is also capable of treating fluoride-contaminated groundwater in field conditions, suggesting it is a promising defluoridation adsorbent. The adsorbent also showed good regenerability potential that would allow re-use, which could make it practically and economically viable. Additional research is, however, required to further increase the fluoride adsorption capacity of developed adsorbent.

Book Synopsis Green Adsorbents by : George Z. Kyzas
Download or read book Green Adsorbents written by George Z. Kyzas and published by Bentham Science Publishers. This book was released on 2015-12-01 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adsorption technology is a promising avenue for wastewater treatment. Numerous adsorbent materials are presently synthesized. Green or environmental friendly adsorbents are derived from plants and agricultural crop sources, giving them a very low production cost when compared to synthetic polymers. This monograph explains the basic principles of green adsorption technology, their production processes and strategies to remove different categories of environmental pollutants (dyes, heavy metals and phenols/pesticides). The book explains details in terms of features such as adsorption capacity, physico-chemical kinetics and reuse potential. A summary of the economics and future prospect for green adsorption technology is also given. This text is a handy reference for environmental chemistry students, researchers and policy makers.
