Abstract | dc.description.abstract | Cadmium (II) electrode based on plasticized PVC membranes with 1-furoyl-3,3-diethyl thiourea as ionophore and tributyl phosphate as plasticizer has been developed. The membrane was applied on a support of conducting epoxy resin. Some parameters of evaluation of the electrode are presented in this work. The constructed electrode showed linear response in the concentration range of 10(-6) -10(-3) mol/dm(3), had a slope of 28.5 mV/decade, a detection limit (DL) of 2.10(-6) mol/dm(3) and a lower limit of lineal range (LLLR) of 4.2. 10(-6) mol/dm(3). The static response time obtained was less than 20 seconds. The Cd/S relationship in the membrane was 1: 1, as was determined by chemical microanalysis of energy dispersive X-ray spectroscopy (EDS). The constructed electrodes had a life-time of 5 days. | en |
