摘要
本文提出了 Cd( ) - KI-甲基紫三元配合物体系光度法测定 Cd( )的新方法。该方法灵敏度高 ,ε=5 .2 5× 10 5L·mol- 1·cm- 1 ,选择性好 ,精密度可靠 ,用于水中痕量镉的测定 ,结果令人满意。
The spectrophotometric determination of trace cadmium with the ternary complex system of Cd(Ⅱ)\|KI\|MV\|polyethyleneglycol has been introduced.The method has high selectivity and precision.The method has been used to determine trace cadmium in water with satisfactory results.
