Carbon Paste Electrodes for the Analysis of Some Agricultural Pollutants and Trace Metals

Popis výsledku v původním jazyce

The work is concerned with the voltammetric application of unmodified tricresyl phosphate carbon paste electrode (TCP-CPE) and in situ bismuth film-modified tricresyl phosphate-based carbon paste electrode (BiF-TCP-CPE). The TCP-CPE was examined with themain objective of using it for the DPV analysis of some neonicotinoid insecticides in aqueous Britton-Robinson buffer solution pH 7.0 as supporting electrolyte. After comparing the performance of the TCP-CPE with that of silicone oil carbon paste electrode, quantitative analysis of imidacloprid, thiamethoxam and clothianidin was performed in model solutions and real samples. BiF-TCP-CPE was tested for a simultaneous detection of selected heavy metal ions at a ug/dm3 concentration level using SWASV technique. Film formation was studied at untreated, pre-cathodized and pre-anodized TCP-CPEs in the acetic buffer solution pH 4.6, containing 1 ug/cm3 Bi(III).
