叶青双;2-氨基-5-巯基-1,3,4-噻二唑;反相液相色谱
摘  要:
用反相液相色谱法测定水中叶青双及其降解物2-氨基-5-巯基-1,3,4-噻二唑,平均回收率分别为91.7%和94.2%;对水样的最低检测浓度分别为7.19 nmol/L和2.87 nmol/L;叶青双与2-氨基-5-巯基-1,3,4-噻二唑的分离度为2.5。此方法在柱效和灵敏度上比硅胶柱液相色谱法有明显的提高。

摘  要:
This paper presented a method of reversed phase high performance liquid chromatography to determine the germicide N,N-methylene-bi-(2-amino-5-mercapto-1,3,4-thidiazole)(MBAMT) and it's decomposition product 2-amino-5-mercapto-1,3,4-thidiazole)(AMT).Recoveries of MBAMT and AMT were 90% and 94% respectively.The detected limits of concentration for water sample were 7.19 nmol/l for MBAMT and 2.87 nmol/l for AMT.The resolution between the peaks of MBAMT and AMT was 2.5.The column efficiency and detected sensitivity of this method were significantly better in comparision with normal phase chromatography.
