介绍了用ＲＰ－ＨＰＬＣ对镀锌液中添加剂４－苯基－３－丁烯－２－酮与２，２’－二萘基甲烷－６，６’－二磺酸钠进行分离与测定的方法。这一研究可以排除镀液中各组份的相互干扰。镀液先经ＨＰＬＣ柱分离，然后当各组份通过紫外－可见检测器时，其含量就可被分别检测出来。在该方法中，紫外检测器波长定为２９０ｎｍ，流动相为甲醇－水（６０：４０）的混合液，色谱柱ＹＷＧ－Ｃ１８Ｈ３７，４×１５０ｍｍ。结果色谱峰面积与响应值呈很好的线性关系。２，２’－二萘基甲烷－６，６’－二磺酸钠的保留时间是１．１０ｍｉｎ，相关系数０．９９９３，回归方程Ｙ＝４．２１３＋１９５．５４Ｘ，线性范围０．０５０～０．４５０ｍｇ／ｍｌ；４－苯基－３－丁烯－２－酮的保留时间是５．１０ｍｉｎ，相关系数０．９９９７，回归方程Ｙ＝０．１５６＋１７５８Ｘ，线性范围０．００２５～０．０２２５ｍｇ／ｍｌ。
The separation and determination of 4-phenyl-3-buten-2-one and 2,2’-dinaphthylmethane-6,6’-disulfonate as additives in zinc plating solution by RP-HPLC method. This study can rule out the mutual interference of the components of the bath. The plating solution is first separated by HPLC column, and then the content of each component can be detected separately when it passes through the UV-Vis detector. In this method, UV detector wavelength is set at 290nm, the mobile phase is methanol - water (60:40) mixture, column YWG-C18H37, 4 × 150mm. Results The peak area and response value showed a good linear relationship. The retention time of sodium 2,2’-dinaphthylmethane-6,6’-disulfonate was 1.10min, the correlation coefficient was 0.9993, the regression equation was Y = 4.213 + 195.54X, the linear range was 0.050 ~ 0 . The retention time of 4-phenyl-3-buten-2-one was 5.10 min, the correlation coefficient was 0.9997, the regression equation was Y = 0.156 + 1758X, the linear range was 0.0025-0.0225 mg / ml.
