摘要: 利用锡离子及亚铁离子在磷酸二氢钠缓冲溶液形成沉淀物被除去方式进行样品预处理,以安捷伦ZORBAXEclipseXDB-C18色谱柱为分离柱,以20mmol/L磷酸二氢钠溶液-甲醇体系(48∶52)为流动相,215nm为波长检测条件,提出了监测电渡液中有效添加剂(α-萘酚聚氧乙烯醚,α-萘酚磺酸聚氧乙烯醚)含量的高效液相色谱法(HPLC).此方法样品损失率小于4%,α-萘酚聚氧乙烯醚和α-萘酚磺酸聚氧乙烯醚的平均回收率为966%~989%,分析结果偏差在005g/L之内.该方法快速、准确、灵敏度高、重现性好,完全满足镀锡工艺监测的要求.

Abstract: A high performance liquid chromatographic (HPLC) method was established for the analysis of αnaphthol polyoxyethylene ether and αnaphtha sulfonate polyoxyethylene ether in tinplating solution. Plating solution was first treated with sodium phosphate dibasic to detach Sn2+ and Fe2+. The extracts were then cleanedup by high performance liquid chromatography with an ultraviolet detector on a Agilent ZORBAX Eclipse XDBC18 column by UV at 215 nm, using 20 mmol/L sodium phosphatemethanol (48∶52) as a mobile phase. The average recoveries of this method were in the range of 966%~989%. The deviation of HPLC was less than 005 g/L.The proposed method was fast, accurate, sensitive, reproducible, and it could meet the requirement of tinplating process.

Key words: HPLC, tinplating solution, additive, sodium phosphate dibasic, tinplating process
