本文研究了8-羟基喹啉碳糊修饰电极的制作,讨论了其性能,并实验了电极处于最佳状态的条件及使用寿命,用于发样中铊含量的测定,其检出下限为2×10~(-10)mol/L。在5×10~(-9)～2×10~(-7)mol/L范围內铊浓度与峰高呈线性关系?⒍缘缂ぷ鞯脑斫辛颂教帧?
In this paper, the preparation of 8-hydroxyquinoline carbon paste modified electrode was discussed, its performance was discussed, and the conditions and service life of the electrode in the best condition were tested. The detection limit of thallium was 2 × 10 ~ (-10) mol / L. There is a linear relationship between thallium concentration and peak height in the range of 5 × 10 -9 ~ 2 × 10 -7 mol / L.
