This triiodide nsor is bad on triiodide-piroxicam ion-pair complexation. Four main variables, namely, the PVC, plasticizers, ion pair amounts, and pH value were changed during CCD. A total of 27 experiments (27 electrodes) were
designed. The electrodes were prepared by incorporating the ion-exchanger in a PVC matrix plasticized with 2-nitrophenyl octal ether without any additives. The slopes of the calibration curves of the constructed electrodes were collected as the respon. In order to optimize the conditions, mathematical model equations were derived 梅花怎么写
