Stripping voltammetry for the simultaneous determination of iron and copper in water on organo-modified electrodes
Main Article Content
Abstract
The new method worked well to simultaneously determine iron and copper in samples on organo-modified electrodes. The optimal voltammetry was established: EDTA concentration 0.02M; pH = 3-4; deposition potential -1,0V; deposition time 30s. The determining range of iron in water was 0.05 - 60 mg/l, and copper 0.03 - 40 mg/l.
