Chlorite and chlorate are potential health-threatening by-products in drinking water disinfected by chlorine dioxide. Both can be adsorbed and thus removed by calcium carbonate. However, little is known on the adsorption dynamics of calcium carbonate to those by-products. In this study, adsorption ...

The geochemistry of calcium carbonate-rich sediments from a variety of environments throughout the Bahamas was investigated with particular emphasis on the factors that control the pore water chemistry. Most sediments are supersaturated with respect to aragonite, the most abundant carbonate component. Expe...
