土壤中绿黄隆残留量分析方法的研究 总被引:2,自引:0,他引:2
本文确立了土壤中绿黄隆残留量的间接气相色谱分析方法,用0.15mol/L NaHCO3提取土样,二氯甲烷洗涤初步纯化后,在水浴上加热水解,再用二氯甲烷萃取,弗罗里硅土柱净化,最后用气相色谱-电子捕获检测器检测水解产物邻氯苯磺酰胺。土壤中添加回收率78.5%-90.8%,检测极限0.3ng/g。 相似文献

An RP-HPLC method for the quantitative deternunation of imazethapyr in technical product and formula-ion has been developed. Operating conditions were YWG-C18 colunmn,25cm×5.0mm i.d,methanol-water-glacial acetic acid(80 : 20: 1. 2 ,volume ratio) eluent and UV-254nm dstection.The method is reproducibieand the coefficient of variation was less than 1.5%. 相似文献
