✦ Synopsis

Ah&met

An automatic system for the III situ determmatlon of dissolved Cu, Zn, Pb and Cd m fresh waters, composed of a filtration umt, a separation and ennchment umt and an electrochermcal unit for dlfferentlal-pulse anodlc stnppmg voltammetry, was mvestrgated The filtration and ennchment units were designed to estabhsh the most effective expernnental conditions for the measurement of metal concentrations at environmental levels The system was budt for mstallatlon m a buoy equipped Hnth a faclhty for radlotransnussion of obtamed data
