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。
A method for the determination of trace manganese with I_3 ~ - starch system was proposed. The method has high sensitivity and ε = 1.12 × 10-5L · mol -1 (-1) cm -1 with good selectivity. In addition to Fe ~ (3 +) other elements almost no interference. Measured the natural water of manganese, the result is satisfactory.
