Perspectives of Carbon Paste Electrodes in Stripping Potentiometry

open access: yesAnalytical Sciences, 2002
The testing of various types of carbon paste electrodes (CPEs) for their use in stripping potentiometry was carried out by means of specially proposed procedures and by using various model analyte systems. CPEs containing three different pasting liquids (paraffin oil, silicone oil, tricresyl phosphate) were tested as supports for mercury- and gold ...
