Available in PDF, EPUB and Kindle. Book excerpt: Adsorption of the herbicides atrazine, diuron, and simazine and metabolites DIA (de-isopropyl-atrazine) and DEDIA (de-ethyl-de-isopropyl-atrazine) were studied on an activated carbon fiber (ACF) using a batch test method. The specific surface area (1,217m2/g) and mean micropore width (1.24 nm) of ACF were determined by measuring the N2 adsorption at 77K ( -196°C). Boehm's titration method and pH drift method were used to determine amount of surface functional group (total acidity: 238 meq/g and total basicity: 498 meq/g) and pHP̳Z̳C̳ (7.49), respectively. Single component adsorption and competitive binary adsorption isotherm experiments were conducted for low initial concentrations (20 ppb to 500 ppb). The Freundlich isotherm models described the single component adsorption process well (r2> 0.96 in all cases); however, there was a discrepancy between expected and observed adsorption capacities because of some uncertainty in Ko̳w̳ values of the solutes and differences in the geometry of the molecules. The Ideal Adsorbed Solution Theory (IAST) was used to describe competitive binary adsorption. The IAST was well adapted to describing competition involving the weakly adsorbed compounds (DIA and DEDIA), but the IAST proved less appropriate for describing competition among highly adsorbed compounds (atrazine, diuron, and simazine).

This book was released on 2004-01-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many water treatment plants need to remove objectionable trace organic compounds, and activated carbon adsorption is often the best available technology. Utilities face the challenge of having to choose from a large variety of activated carbons, and iodine number or BET surface area values are often utilized in the selection process. Although neither parameter correlates well with adsorption capacities, alternative activated carbon selection criteria based on fundamental adsorbent and adsorbate properties are lacking to date. The first objective of this research was to systematically evaluate the effects of activated carbon pore structure and surface chemistry on the adsorption of two common drinking water contaminants: the relatively polar fuel oxygenate methyl tertiary-butyl ether (MTBE) and the relatively nonpolar solvent trichloroethene (TCE). The second objective was to develop simple descriptors of activated carbon characteristics that facilitate the selection of suitable adsorbents for the removal of organic contaminants from drinking water.Originally published by AwwaRF for its subscribers in 2003 This publication can also be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below

Available in PDF, EPUB and Kindle. Book excerpt: Over the past 50 years, triazines have made a great impact on agriculture and world hunger by assisting in the development of new farming methods, providing greater farming and land use capabilities, and increasing crop yields. Triazines are registered in over 80 countries and save billions of dollars a year. The Triazine Herbicides is the one book that presents a comprehensive view of the total science and agriculture of these chemicals. With emphasis on how the chemicals are studied and developed, reviewed, and used at the agricultural level this book provides valuable insight into the benefits of triazine herbicides for sustainable agriculture. - Presents previously unpublished information on the discovery, development and marketing of herbicides - Includes a vital section on the origin, use, economics and fate of triazine herbicides - Covers benefits of triazines in corn and sorghum, sugarcane, citrus, fruit and nut crops - Establishes best management practice and environmental benefits of use in conservation tillage
