本文研究用四苯硼酸钠与扑尔敏生成缔合物为电活性物质制成,PVC膜扑尔敏敏感场效应管。该传感器对扑尔敏的线性响应范围为:8×10~(-2)～1×10~(-4)mol·L~(-1);其斜率为53mV/Pa(20℃);响应时间约为20s;并有较宽的pH使用范围。应用于扑尔敏注射液和片剂含量的测定,获得了较好的效果。
In this paper, sodium tetraphenylborate and chlorpheniramine are used to form associative materials for electroactive substances, and the PVC film is a chlorpheniramine-sensitive field effect transistor. The linear response range of this sensor to chlorpheniramine was 8 × 10 -2 to 1 × 10 -4 mol·L -1 with a slope of 53 mV / Pa at 20 ° C. The response Time is about 20s; and a wider pH range. Used in determination of chlorpheniramine injection and tablet content, obtained good results.
