PREPARATION AND STUDY OF A 1-FUROYL-3,3-DIETHYLTHIOUREA ELECTRODE

Cadmium (II) electrode based on plasticized PVC membranes with 1-furoyl-3,3-diethyl thiourea as ionophore and tributylphosphate 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 wor...
