The modification of carbon paste electrode (CPE) with molecularly imprinted polymer (MIP) for determination of rhodamine-B by potentiometry method has been studied. The experiments were performed using glutamic acid as a monomer. The composition of monomers, the number of electropolymerization cycles and pH of the solution were used to describe modification electrodes made (CPE-MIP-s) and the electrode characteristics were evaluated. It was observed the amount of oxidation current signal increase with increasing glutamic acid concentration. The optimal polymerization molar ratio of the functional monomer to the template molecule rhodamine-B was 3:1; the maximum number of electropolymerization was 15 and the optimum pH of supporting electrolyte solution was 4.
