Voltammetric ion-selective electrodes (ISEs) based on poly(3-octylthiophene) (POT) in connection with ultra-thin membranes formulated different selective receptors (i.e., ionophores) are proposed for detection of lead, copper and silver ions (Pb2+, Cu2+ Ag+). The working mechanism the POT-membrane electrode is interconnected charge transfer processes both sides membrane, overall process dependi...
The research was based on a pot experiment in which the impact of increasing Cd, Zn and Pb doses content available trace elements soil compared. Seven series trials were designed: 1 (Cd), 2 (Pb), 3 (Zn), 4 (Cd + Pb), 5 Zn), 6 (Pb 7 Zn). Aside from control one (without metals), three levels contamination considered within each series. Mobile forms (Cd, Pb, Zn, Fe, Mn, Cu, Ni, Co, Cr) determined,...
