Abstract
Equilibrium dialysis and molecular sieve chromatography were employed to evaluate the interactions between humic acids (HA) and a water trea tment algicide, poly[oxyethylene(dimethyliminio)ethylene dimethylimini o)ethylene dichloride (WSCP), and a fungicide, 2-(thiocyanomethylthio) benzothiazole (TCMTB). WSCP exhibited-saturable, reversible binding to HA. The interaction between HA and WSCP was found to be of sufficient magnitude that naturally occurring HA concentrations will have signif icant impacts on the bioavailabity, toxicity and fate of WSCP in the e nvironment. No interaction between HA and TCMTB was detected.
