(Texas A&M University, 2004-09-30)Adsorption kinetics and adsorption-desorption of atrazine on organoclay composites prepared with the surfactant 6-piperazin-1-yl-N,N'-bis-(1,1,3,3-tetramethyl-butyl)-(1,3,5)triazine-2,4-diamine and Houston Black clay were ...
-
(2009-05-15)The objective of this research was to investigate the retention of arsenate (iAsV), arsenite (iAsIII), monomethyl arsenate (MMAsV) and dimethyl arsenate (DMAsV) by calcite and assess the impact of dissolved Ca2+, Mg2+, ...
-
(Texas A&M University, 2006-04-12)Because of As toxicity, the complexity of its chemistry, and the recent lowering of the maximum contaminant level of As in municipal drinking water, there has been considerable interest for improved methods to remove As ...
-
(2016-08-05)With the wide application of nanotechnology in petroleum industry, transportation of nanoparticles in porous media has attracted a growing interest. This thesis focuses on investigating the bulk and adsorption properties ...
-
(2011-05-10)Aflatoxins are toxic metabolites produced by Aspergillus flavus and A. parasiticus fungi. Aflatoxin B1 (AFB1) is the most toxic and is a potent carcinogen with antinutritional and immunosuppressive effects. Several natural ...
-
(Texas A&M University, 2007-04-25)Ammonia emissions from animal feeding operations (AFOs) have recently come under increased scrutiny. The US Environmental Protection Agency (EPA) has come under increased pressure from special interest groups to regulate ...
-
(Texas A&M University, 2004-09-30)A protocol was developed to measure ammonia emission concentrations from dairies using an isolation flux chamber. A hybrid dairy in Comanche county, Texas, was measured for one week each during August 2002 and January ...
-
(2021-07-08)During natural and manmade disasters such as floods and chemical spills, hazardous chemicals can be mobilized in the environment and affect water and food sources. Practical and economically-feasible technologies are needed ...
-
(2013-12-09)Understanding the adsorption of phosphine oxides on silica surfaces has a threefold incentive. (a) Efficiently removing phosphine oxides from reaction mixtures is crucial after many synthetic procedures, for example the ...
-
(2016-07-12)It is a well-known fact that the thermophysical properties of confined fluids (intraparticle) can be significantly different from those of bulk phases (interparticle). Such difference becomes more pronounced as the pore ...
-
(2015-12-01)Aflatoxins are toxic secondary fungal metabolites that are present in a variety of crops. Numerous animal experiments have demonstrated the effectiveness of smectite clay in adsorbing aflatoxin and in reducing the toxicity ...
-
(2016-02-17)Adsorption is valuable for industrial separation and purification processes and the characterization of porous materials. The amount of adsorbate a given adsorbent can take at a given condition and the associated heat ...
-
(2016-04-05)This thesis will explore two different facets of the quest for superior immobilized catalysts: (1) cyclotrimerization of acetylenes with nickel catalysts and (2) solid-state NMR studies of the adsorption and subsequent ...
-
(Texas A&M University, 2005-11-01)Imazethapyr was recently approved for use in rice, but limited information is available regarding its efficacy, environmental fate or potential red rice resistance. Therefore, experiments were conducted to 1) determine the ...
-
(Texas A&M University, 2005-02-17)Produced water handling has been an issue of concern for oil and gas producers as it is one of the major factors that cause abandonment of the producing well. The development of effective produced water management strategies ...
-
(Texas A&M University, 2005-08-29)Arsenic is a toxic element that is widely distributed throughout the earth??s crust as a result of both natural geologic processes and anthropogenic activities. In virtually all environments, methylated forms of arsenic ...
-
(2009-05-15)Hydrogen storage has been identified as a primary bottleneck in the large-scale implementation of a hydrogen-based economy. Many research efforts are underway to both improve the capacity of existing hydrogen storage systems ...
-
(2012-10-19)Saflufenacil is a new herbicide for broadleaf weed control. Limited information is available for crop tolerance, weed control and herbicide behavior in the rice environment. Studies were designed to 1 and 2) evaluate rice ...
-
(2012-02-14)Carbon has been used electrochemically in various forms for water treatment and the carbon aerogel is one of them. Carbon Aerogels (CA) are used as electrodes due to their high surface capacity and high electrical conductivity. ...
