Abstract:

<p> Production of 1,2-propanediol through hydrogenolysis of glycerol over Copper-Chromite is a promising reaction pathway that has large potential markets. However, production is complicated by low catalyst stability and significant difficulty in preventing or removing unwanted reaction byproducts. These unwanted byproducts impart yellow color and foul odor, making the product sell at a much cheaper cost. In collaboration with a commercial partner, the authors investigated an economical way of liquid-liquid extraction for removing these unwanted byproducts. The authors also tried to model the

Abstract:

Methyl methacrylate (MMA) is widely used for a range of polymer products. MMA can be produced from propionaldehyde via the BASF process. n-Propanol is readily available 'in South Africa as a byproduct of Fischer-Tropsch synthesis. This prompted an investigation into the production of propionaldehyde by the dehydrogenation of n-propanol. There is presently no established technology for the dehydrogenation of n-propanol to propionaldehyde and there has been very little work carried out on the effect of process variables on propionaldehyde yield.

Abstract:

Arsenic (As), Chromium (Cr), and Copper (Cu) are ubiquitous in soils as a result of anthropogenic and geogenic processes. The fate of As, Cr, and Cu in the environment is largely governed by their speciation, which is influenced by soil physiochemical properties. This study investigated the influence of soil physiochemical properties and landscape position on As, Cr, and Cu concentration and speciation in soils adjacent to Chromated Copper Arsenate (CCA) treated lumber fence posts. Concentration gradients showed elevated total As and Cu adjacent to the three fence posts, which decreased with i

Aluminium alloys are frequently pre-treated by a conversion coating before application of an organic coating in order to improve the corrosion resistance and adhesive properties of the surface and the corrosion resistance provided by the system.

Therefore, alternative, so-called chromium-free conversion coatings are being developed that are more environmentally-compliant.The purpose of the present work ha

Abstract:

Chromated copper arsenate (CCA) is a biocidal chemical used by the wood preservation industry to extend the service life of wood products. CCA is currently the most commonly used wood preservative in British Columbia. Environmental concerns regarding the fate of CCA solutions accidentally released or chronically spilled to unpaved ground at wood preservation facilities has led to the present investigation on the retention and release of CCA constituents in soils. Batch and column tests were used to evaluate the adsorption and desorption of arsenic, chromium and copper in several B.C. soils. B

Abstract:

Wipe sampling is a means of monitoring exposures to contaminants which has been used extensively for assessment of lead (Pb) in housedust in the U.S. This thesis reports the first baseline wipe dataset for urban Canadian homes, for Pb and other metal(loid)s including: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), and antimony (Sb). The literature review covers sampling methods, health effects, and sources. The digestion procedure ASTM 1644 is the accepted HNO3 hotplate protocol for determination of Pb in wipes. However in this study, HF was added to enhance extraction ef
