Determination of polymeric organic material containing “N-catalyst” in seawater by constant current chronopotentiometric stripping analysis

Catalytic properties and surface activity of nitrogen containing polymeric organic material (N -POM) were analyzed by constant current chronopotentiometric stripping analysis (CPSA) in 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.
