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 parameter were applied like linearity, accuracy, precision, limit of detection, limit of quantification and specificity ER -
