摘要
目的:建立并验证了用HPLC-UV测定皮革中含氯苯酚的方法;方法:以丙酮为溶剂,采用超声提取法提取皮革中含氯苯酚,用甲醇定溶,以相对保留时间定性,峰面积进行定量;结果:该方法回收率为92.39%~100.32%,RSD为1.094%~1.377%,检测限(S/N=3)分别为2,3,5,6-四氯苯酚:0.014 mg/L;五氯苯酚:0.002 mg/L;2,4,6-三氯苯酚:0.004 mg/L;结论:本方法具有方便快捷、灵敏度高、回收率高、精密度好的特点,且试剂用量少,避免了大量化学试剂的使用,减少了环境污染,用来测定皮革中含氯苯酚的含量是简单可行的。
Objective: The determination method of chlorinated phenols in leather was established and demonstrated in this paper;Method: The chlorinated phenols in leather were distilled with the help of ultrasound by taking acetone as the solvent and mixed with methanol.And the quality and quantitation were determined by the relative keeping time and peak area;Result: The yield was 92.39%~100.32%,RSD was 0.94%~1.377%,and the detection limit(S/N=3) was 2,3,5,6-tetrachlorophenol,PCP and 2,4,6-trichlorophenol were 0.014mg/L,0.002mg/L and 0.004mg/L,separately.And conclusion: Many advantages have been found in the method,such as simple,convenient and sensitive with high recovery and precision.And at the same time the environmental pollution can be reduced to a low level due to the lower chemical reagents usage.This method is suitable for determining the chlorinated phenols in leather.
