中文摘要：
研究了一种以玻碳为基底电极，掺杂钴-氧化钻的聚苯胺为中间体，层状镁铝复合金属氧化物PVC膜为敏感膜，具有双层膜结构的固态磷酸根离子选择电极。该电极的检测磷酸二氢根的线性范围在10^-1 -10^-4mol/L之间，响应斜率为-32．3mV／dec，检测下限为7．65×10^-5 mol/L，电极响应时间较快，且具有较强的稳定性和抗干扰能力。
英文摘要：
A phosphate ion-selective electrode, which is based on glassy carbon electrode as basal electrode, polyaniline doped cobalt ions as transducer layer, and layered Mg/A1 complex metallic oxide PVC membrane as sensitive memberance, double solid state phosphate anion seleetion electrode with double membrane is studied. The results show that the electrode has a linear potential response at concentration range of 10^-1- 10^-4 tool/L, with a slope of -32.3 mV/dec and a detection limit of 7.65 × 10^-5 mol/L, it has short response time, good stability and capacity of resisting disturbance.
