摘要
提出了 I_3^--淀粉体系测定痕量锰的方法。本法灵敏度高,ε=1.12×10~5L·mol^(-1)·cm^(-1),选择性好。除 Fe^(3+)外其它元素几乎无干扰。实测了天然水中锰,结果令人满意。
The method that trace manganse is determined with I_3^--starch system has been put forward in this paper.This is a very sensitive(ε=1.12×10~5L·mol^(-1)·cm^(-1))and selective method.Other elements,except Fe^(3+),almost are no interference.The results of the test of manganese in nature water are satisfaction.
