摘  要:
建立高效液相色谱法测定代森锰锌杂质乙撑硫脲(ETU)的定量方法,以甲醇+乙腈+水作为流动相,使用C18柱,成功地测定出代森锰锌杂质乙撑硫脲(ETU)的含量。其标准偏差为0.67,变异系数为0.69%,回收率100.01%,相关系数0.9996。

摘  要:
A method for determination of ethylenethiourea in the mancozeb by HPLC with ultraviolet detector and C18 column, using methnol and acetonitrile and water (4.5+3.5+92) as mobile phase was described in this paper. The results show that the standard deviation is 0.67, the variation coefficient is 0.69%, the average recovery is 100.01%, linear correlation is 0.999 6.
