摘要
本文研究结果表明,在pH=1.0~2.0的酸性溶液中Fe3+与KI作用游离出碘,以CCl4萃取光度法测碘[1,2],用于间接测定焊剂中Fe3+的含量。
The analysis method of Fe3+ in solder was developed using I2-CCl4 extraction spectrophotometry. Fe3+ in solder can indirectly be analysed by spectrophotometry of I2 in CCl4 solution, which was released by action of Fe3+ with KI solution (pH=1. 0~2. 0).
