摘要
目的测定苯酚甘油滴耳液中苯酚的含量.方法采用紫外分光光度法测定苯酚甘油滴耳液中苯酚含量,测定波长270±1nm.结果平均回收率为98·67%,相对标准偏差(RSD)为0·72%.结论该法操作简便,与碘量法测定结果比较无显著差异(P>0·05).
OBJECTIVE To establish a method for determination of phenol in phenol glycerine. METHODS The UV spectrophotography was used, the detection wavelength was 270 ±1nm. RESULTS The average recovery was 98. 67%, and RSD was 0. 72%. CONCLUSION The method was sample,easy to operate,and there was no significant different compared to the iodimetry.
