Determination of humic substances in natural waters by cathodic stripping voltammetry of their complexes with iron

A new voltammetric method is presented for the measurement of humic substances (HS) in natural waters. The method is based on catalytic cathodic stripping voltammetry (CSV) and makes use of adsorptive properties of iron–HS complexes on the mercury drop electrode at natural pH. A fulvic acid standard...
