Association of triorganotin compounds with dissolved humic acids

Article Abstract:

A discrete log K spectrum model with four binding sites was utilized to analyze the reactions of pH and sodium iron content on dissolved organic matter (DOM) with organic cations including tributyltin (TBT) and triphenyltin (TPT). The relation of triorganotin compounds with humic acids was investigated in recognition of the lack of information on DOM and hydrophobic organic cations. Results showed triorganotin compound cation by negatively charged ligands significantly influenced sorption in the assessed pH range.

Cobalamin-mediated reduction of cis- and trans-dichloroethene, 1,1-dichloroethene, and vinyl chloride in homogenous aqueous solution: reaction kinetics and mechanistic considerations

Article Abstract:

Superreduced cobalamin, in the presence of the electron donor titanium (III) citrate, dechlorinates vinyl chloride, 1,1-dichloroethene, and both the cis and trans structures of dichloroethene when these compounds are present in a homogenous aqueous solution. The reductive dechlorination results in the production of ethene and ethane. The procedure is dependant on the pH levels.
