Abstract
Influence of nafion membranes of various thickness on performance of t he mercury film electrode in the differential-pulse anodic stripping v oltammetric determination of copper, lead, and cadmium, in the presenc e of nonionic and ionic surfactants, has been investigated. The modifi ed electrode eliminates, at least partly, the interference from surfac tants up to their concentration of 100 ppm, in particulate for lead an d cadmium. The results of determination of heavy metals in acidic extr acts of sludges from biological waste water treatment and soils and in waste waters are presented and compared with those obtained by ICP OE S.
