摘　　要：在镀锡液中,经常由于有杂质铁离子的存在而使镀液的效能下降。使用粉煤灰作为吸附剂,研究了粉煤灰对含有Fe2＋、Sn2＋溶液中的金属离子的吸附规律。实验使用邻菲罗啉吸光光度法对镀锡液中的Fe2＋进行了测定,使用碘量法对Sn2＋进行标定。研究结果表明,10 g/L粉煤灰,粒径为33~55μm,θ为50℃时对Sn2＋的吸附量最小,对Fe2＋的吸附量接近最大值。In tin plating solution, the efficiency of the plating solution will be always decreased because of performance of Fe2 ＋ and Sn2 ＋ existed in the electroplating solution. The results showed that the pulverized fuel ash adsorption capacity of Sn2＋ reached the minimum and Fe2＋ almost reached the maximum when ash content was 10 g/L, particle size was 33 - 55 μm and the temperature was 50 ＋
