本文建立了用毛细管电泳法分析制革液中硫化物的检测，使用内层线性丙烯酰胺柱可以有效减少电渗流，运行溶液为０．０５ｍｏｌ·Ｌ－１的磷酸盐溶液，ｐＨ＝８．４，负电压分离，分离电压１０ｋＶ，高差压力进样，进样高１０ｃｍ，时间１０ｓ，紫外检测波长２１４ｎｍ，样品保留时间和峰高的相对偏差为２．１％和３．０％。最小检测量０．１μｇ／ｍＬ，在０．４１～６．５６μｇ／ｍＬ范围内相关系数０．９９９２，回收率９２％～１０６％。
This paper established a capillary electrophoresis analysis of tanning liquid tannin detection, the use of inner linear acrylamide column can effectively reduce the electroosmotic flow, the running solution is 0.05mol · L-1 phosphate solution, pH = 8.4 , The separation of negative voltage, the separation voltage of 10kV, high pressure injection, injection height 10cm, time 10s, UV detection wavelength 214nm, sample retention time and peak height relative deviation of 2.1% and 3.0%. The minimum detection limit was 0.1μg / mL. The correlation coefficient was 0.9992 in the range of 0.41 ~ 6.56μg / mL with the recovery of 92% ~ 106%.
