摘要
采用高效液相色谱法测定烯草酮合成废液中4-二甲氨基吡啶含量,使用BDS Hypersil C18不锈钢柱(250mm×4.6mm),以甲醇∶水∶磷酸=60∶39.75∶0.25为流动相,使用紫外检测器,在波长254nm下进行测定。实验测定4-二甲氨基吡啶加标回收率为97.7%,变异系数为3.33%,线性相关系数为0.9994。
HPLC was used for the determination of 4-dimethylaminopyridine in the waste liquid of clethodim synthetic,using of BDS Hypersil C18 stainless steel column（ 250 mm × 4. 6mm） with methanol-water-phosphate = 60： 39. 75： 0. 25 as the mobile phase and UV detection at 254 nm. The experiments show that determination 4-dimethylaminopyridine recovery is 97. 7%,RSD（ n = 6） for 4-dimethylaminopyridine is 3. 33%. The linear correlation coefficient is 0. 9994.
