本文提出固定时间标准校正比较法,用碘离子选择性电极为指示电极研究了Cu~(2+)-S_2O_8~(2-)-I~-反应体系催化测定痕量Cu~(2+)的最佳条件并应用于实际分析。
In this paper, a fixed time standard calibration comparison method was proposed. The catalytic effect of Cu ~ (2 +) - S_2O_8 ~ (2 -) - I ~ reaction system on the determination of trace Cu ~ (2+) with iodine ion selective electrode was studied. The best conditions apply to the actual analysis.
