摘 要:建立了20%增效可溶性噻枯唑(MBAMT)粉剂中有效成分MBAMT的高效液相色谱(HPLC)分析方法。采用硅胶柱,正已烷:无水乙醇=9:2(V/V)为流动相,所得结果良好,平均回收率为93.75%,变异系数为2.18%。方法简易、快速、准确,已用于产品质检。
Quantitative Determination of 20% MBAMT Wettable Powders by High Performance Liquid Chromatograph MENG Di-ya(Agricultural Testing Center
of Hubei Academy of Agricultural Sciences,Wuhan 430064, China) Abstract:The HPLC method for determination of MBAMT (N, N'-methylene-bis
(2-amino-5-mercapto-1,3,4-thiadia-zole)has been reported. The sample was
analyzed on a SiO2 column with mobile phase of n-hexane: ethyl
alcohol=9:2(V/V)using UV detector at 320 nm. The variation coefficient, recovery
were 2.183% and
93.76%,
respectively. The analytical results show that this method is simple, rapid and
accurate. |
