| Abstract: | A new detection method of total phenol based on automatic measuring instrument was introduced,and the results of this method were compared with traditional manual detection methods.The results show that the detection limit of the instrument is 0.0045 mg/L,and the error rate is less than 97%,the precision is less than 95%,and the spike recovery is 96%~103%.Compared with the traditional manual titration method,the error of the new detection method of total phenol is smaller,which can reduce the contact between laboratory personnel and toxic drugs. |
