摘要
应用高效液相色谱法同时测定镀铜光亮剂中的多种有机添加剂。实验选用Ｃ６Ｈ５基柱，流动相为Ｖ（甲醇）ｖＶ（水）＝ ３０ｖ７０，流速１．５ ｍ Ｌ／ｍ ｉｎ，检测波长为２１０ ｎｍ 。在常温条件下，２－巯基苯并咪唑（Ｍ）、乙撑硫脲（Ｎ）、聚二硫二丙烷磺酸钠（Ｓｐ）得到较好的分离，方法简便、快速。
This paper describes a high performance liquid chromatographic method for analysis of organic additives in copper\|plating brightener. The copper\|plating brightener was filtered through 0.45 μm micropore membrane and determined on a Spherisorb\|C\-6H\-5 column, with V (methanol)∶ V (water)=30∶70 mobile phase at the flow rate of 1.5 mL/min, and detected at UV 210 nm.2\|benzimidazolethiol,ethylene thiourea,1\|propanesulfonic acid 3,3′\|dithio\|bis\|disodium salt were separated and determined. The recoveries were more than 99% with CV less than 1%. The method is simple and rapid.
