叶青双及其降解物在水环境中的光降解

The Photodegradation of MBAMT and Its Decomposed Product in Water Environment.

提出了一种用反相液相色谱测定水中叶青双及其降解物２ － 氨基－ ５ － 巯基－ １ ，３ ，４ － 噻二唑的方法。叶青双及主要降解物２ － 氨基－ ５ － 巯基－ １ ，３ ，４ － 噻二唑在水中的光降解都非常迅速， 降解半衰期叶青双为１ ．２０ ～２ ．２２ ｈ ； ２ － 氨基－ ５ － 巯基－ １ ， ３ ，４ － 噻二唑为２ ．２５ ～２ ．３４ ｈ 。

This paper presented a method of reversed phase of HPLC to detect the fungicide MBAMT and its decomposed product 2-Amino-5-Mercaptoe-1,3,4-Thidiazole (AMT). The photodegradation of MBAMT in water was very fast. The half-life of MBAMT in water was 1.20 to 2.22h. The photodegradation of AMT in water was very fast too. The half-life of AMT was 2.25 to 2.34h.
