摘要/Abstract

摘要： 本文所述有机磷传感器是以P.V.C为载体,磷酸酯及相应的有机磷电敏感物质按一定比例混合作为电活性物质研制而成的。对传感器性能进行测试,其响应时间≤20s,最低检出限≤0.1×10-6,选择性系数均≤0.1,实验证明它是一种较为方便的有机磷农药快速检测仪器设备。

关键词: 有机磷传感器, 选择性系数, 最低检出限

Abstract: Organic phosphorus sensor has been instrumented with P.V.C as mem brane Carrier mixed with the phosphate andthe electric sensitive matter of organic phosphorus as active component. We have tested the sensor characteristics: the response-time was short (≤20s), the detection minimum is lower than 0.1×10-6 and the selectivity coefficient is lower than 0.1. It wasa kind of convenient and speedy determination instrument for assaying crganic phosphorous pesticides.

Key words: organ phosphorus sensor, selectivity coefficient, detection minimum
