摘要
研究了１－甲基－２－吡咯烷酮在玻碳（ＧＣ）电极表面聚合的条件，测试了Ｉ－－聚１－甲基－２－吡咯烷酮化学传感器的电化学性能。所制电极检测Ｉ－响应线性范围２４×１０－４～０１ｍｏｌ／Ｌ，检测下限为１０×１０－４ｍｏｌ／Ｌ，电极的重现性及稳定性都较好，重复测定７次相对标准偏差为０７１％，可连续使用２５天。Ｃｌ－、Ｂｒ－、ＮＯ－３。
Polymerization of 1 methyl 2 pyrrolidone on the surface of glassy carbon electrode was studied The electrochemical behavior of this chemical sensor was tested by cyclic voltammetry The linear response for iodide ion ranges from 2 4×10 -4 to 0 1 mol·L -1 ,while the detection limit is 1 0×10 -4 mol·L -1 The reproducibility and stability of the electrode are quite good The relative standard deviation of 7 parallel measurements is 0 71% The electrode can be used continuously for 25 days The interference of chloride,bromide,nitrate and sulfate is small
