中文摘要	提出了高效液相色谱法测定水中痕量甲磺隆. 水样经Oasis~R MCX固相萃取小柱富集并净化后,以Extend C18柱(250 mm*4.6 mm,5mum)为固定相,0.2 mol·L~(-1)甲酸-甲醇-乙腈 (60+20+20)混合溶液为流动相进行分离,在225 nm波长处,用二极管阵列检测器测定. 甲磺隆浓度在0.005~5.0 mg·L~(-1)范围内与其峰面积呈线性关系,测定下限(10S/N)为0.005 mg· L~(-1). 方法用于水样分析,加标回收率在94.0%~102.0%之间,相对标准偏差(n=6)小于6.5%
英文摘要	High performance liqiud chromatography with solid phase extraction was applied to the determination of residual amount of metsulfuron-methyl in water. The sample was enriched and purified by Oasis MCX SPE column. The eluate obtained was separated on Extend C_(18) column (250 mm*4.6 mm, 5mum), using a mixture of 0.2 mol·L~(-1)formic acid, methanol and acetonitrile mixed in the ratio of 60 to 20 to 20 (by volume) as mobile phase. DAD-detection at 225 nm was used in the determination. Linear relationship between values of peak area and mass concentration of metsulfuron-methyl was kept in the range of 0.005-5.0 mg·L~(-1). Lower limit of determination (10S/N) of the method was found to be 0.005 mg·L~(-1). On the base of water sample, test for recovery were made by standard addition method, values of recovery found were in the range of 94.0%-102.0%, and values of RSD′s (n=6)were less than 6.5%
