研制了双管氯离子选择性微电极(端径8-10μm)。测试了电极的线性响应范围、检测限和选择性系数等性能,结果表明,在纯Cl~-的标准溶液中电极的线性范围为1.0 ×10~(-4)～1.0mol/L,斜率为58.8,检测下限为2.51×10~(-4)mol/L。电极在以台氏液为底液的Cl~-标准溶液中线性范围为1.0×10~(-2)～1.0mol/L,斜率为52.5。采用固定干扰离子法测
A double-tube chloride-selective microelectrode (8-10μm in diameter) was developed. The linear response range, detection limit and selectivity coefficient of the electrode were tested. The results showed that the linear range of the electrode was 1.0 × 10 ~ (-4) ~ 1.0 mol / L in pure Cl ~ - 58.8, the detection limit was 2.51 × 10 -4 mol / L. The linear range of the electrode in Cl ~ - standard solution with Tyrode ’s solution is 1.0 × 10 ~ (-2) ~ 1.0mol / L with a slope of 52.5. Using fixed interference ion method
