邻菲罗啉分光光度法测氯乙烯单体中含铁

Determination of iron in VCM by o-phenonthroline spectrophotometry

介绍了用邻菲罗啉分光光度法对氯乙烯单体中铁含量的测定方法,并就吸收曲线、邻菲罗啉铁络合物的稳定性、显色剂浓度对照试验、邻菲罗啉与铁的摩尔比、溶液酸度对络合物的影响以及共存离子消除等条件进行了探讨,以更好地满足实际检测工作的需要。

The determination of iron content in VCM by the o-phenonthroline spectrophotometry was introduced. The conditions were discussed to meet the requirements of the determination, which includes the absorption curves, stability of the o- phenonthroline-iron complex, the concentration of developing agent, the mole ratio of o- phenonthroline to iron, the influence of the acid concentration in the solution on the complex and the elimination of the co-ions and so on.
