Abstract
In this work, the construction and performance characteristics of new sensitive and selective modified carbon paste (MCPE) and screen printed (MSPE) potentiometric sensors modified with different ion pair were described for the determination of antispasmodic drug (Oxybutynine HCl) in pure form, biological fluids and pharmaceutical preparations. Many of experimental parameters affecting electrode efficiency were investigated, such as the effect of plasticizer, ion pair type, ion pair content, response time, temperature, effect of pH on the proposed electrodes. Studying of the interfering ions by studying the selectivity behavior of the proposed electrodes .Validation parameters were studied like linearity, accuracy, precision, limit of detection, limit of quantification and specificity
