Chitin, corncobs, and a mixture of chitin and corncobs were tested as potential electron donor sources for stimulating the reductive dechlorination of tetrachloroethene (PCE). Semi-batch, sand-packed columns were used to evaluate the donors with aerobic and anaerobic groundwaters containing varying degrees of alkalinity. In all experiments, acetate and butyrate were the dominant fatty acids produced,...
Air-water partitioning data for a wide range of organic chemicals are used to validate a three-variable quantitative structure-activity relationship (QSAR) model for Henry's law constant, H. The predictive ability of the basic model, developed from a training set of 180 chemicals, is now demonstrated on 105 new chemicals of similar molecular structure. This basic model is then extended to cover...
