Abstract

Catalytic properties and surface activity of nitrogen containing polymeric organic material (N-POM) were analyzed by constant current chronopotentiometric stripping analysis (CPSA) and alternating current (AC) voltammetry in sodium chloride solution (pH 8) and seawater. CPSA proved to be a suitable method for determination of low concentrations of N-POM in seawater by measuring its “ presodium” catalytic peak H. A protein human serum albumin (HSA) (15 % of N) was used as a model compound and the concentration of N-POM from natural seawater samples was expressed in HSA concentration equivalents. Peak H represents an additional parameter for characterization of natural organic matter.
