采用反相高效液相色谱法，以甲醇＋ 水＝ ６５ ＋ ３５（ｖ／ｖ） 为流动相，以呋喃酚为内标物，紫外检测器对氰草津和莠去津水悬剂进行分离和测定。结果表明：氰草津和莠去津含量测定的精密度的标准偏差分别为：０３８ 、０２５ ；变异系数分别为：２０１ ％ 、１３８ ％ ， 回收率分别为：９８９ ％ ～９９５ ％ 、９９７ ％ ～１０２０ ％ ；线性相关系数分别为０９９９４７ 、０９９９１４
Using reversed-phase high performance liquid chromatography (HPLC) with methanol + water = 65 + 35 (v / v) as mobile phase and furanol as internal standard, the UV detector was used to separate and determine the cyanuricum and atrazine aqueous suspension . The results showed that the standard deviations of the contents of cyanuricum and atrazine were 038 and 025, respectively. The coefficients of variation were 201% and 138%, respectively. The recovery rates were 98 9% ~ 995%, 997% ~ 1020%; the linear correlation coefficients were 099947, 099914
