Abstract
When certain chemical and physical parameters were controlled during chlorination of algal extracellular products (ECP), organohalide formation was modified. In general, decreases in temperature and contact time decreased the generation of purgeable (POX), nonpurgeable (NPOX), and total (TOX) organic halide. Decreases in pH increased NPOX but reduced POX and CHOCl3 formation. Under most chlorinating conditions, algal ECP generated more NPOX than POX and CHCl3. The majority of NPOX formed was greater than 1000 daltons. The chloroform-generating potentials of algal ECP and algal biomass were similar but were lower than those reported by others for algal ECP, algal biomass, and humic substances. The organohalide-forming potentials of the blue-green alga studied tended to be higher than those for green algae. (Copyright (c) 1984 American Chemical Society.)
