【摘要】 以乙基紫与碘离子的缔合物（EVI）为电活性物质研制了PVC膜碘离子选抒电极、以正交试验法[1]确定传感膜的最佳组成．给出了电极响应斜率、线性响应范围、电极对I检测下限以及该电极测定Ag＋下限。更多还原

【Abstract】 The ion-pair of ethyl violet ion and iodide ion used as eleetroactive material, dibutyl phthalate used as plasticizer, tetrahydrofuran used as solvent, the iodide ion selective electrode was prepared. The suitable proportion of the sensor was decided by the result of intersection test. The slope of the calibration, the linear range and the detectable limit are given.更多还原
