摘要:采用分光光度法,利用PAN-6S与铜的显色反应,测定钢铁中的铜含量.在pH值为6~8内,PAN-6S与Cu2+生成1∶1的红色配位化合物,最大吸收峰在545 nm处,铜含量在0~30μg/25 mL时符合比尔定律,摩尔吸光系数为3.12×104.加入掩蔽剂后,可直接测定钢铁中铜的含量,能够简化操作过程,避免使用有机溶剂,减轻污染.
Copper content in steel is determined by spectrophotometry using chromogenic reaction of PAN-6S and copper. 1:1 red complex is produced by reaction of PAN-6S and Cu2+ at pH=6-8, and the maximum absorption peak is at 545 rim. The copper content conform to Bill law in 0 - 30μg/25 mL and molar absorptivity is 3.12×104. Copper content can be determined directly after adding masking agent. The method can simplify operation process avoids organic solvent can reduces pollution.
