目的建立一种快速检测碎米中有机磷农药残留量的方法,用于注射用葡萄糖原料碎米的质量监控。方法采用气相色谱法与氮磷检测器(NPD)快速检测碎米中的12种农药残留。结果所建立的方法学的线性范围是0.1~5.0 ppm、检出限为0.98~6.24 ppb、检测限为3.27~20.8 ppb、相关系数均大于0.999 5;精密度、重复性的RSD均在6.3%以下;回收率在87.25%~108.4%。结论本文建立了碎米中有机磷农药残留的快速检测方法,为注射用葡萄糖的制备筛选出合格的碎米原料提供了有效保障。

〔Abstract〕objective To establish a determination method of the organophosphate in the broken rice,which can be used to control the glucose-injection quality.M ethods 12 kinds of pesticides residues were rapid detected by using gas chromatography adding NDP detector.Results The linear range in the established determination method was 0.1~5.0 ppm,the limit of detection was 0.98~6.24 ppb,the limit of qualification was 3.27~20.8 ppb,and the correlation coefficient were all more than 0.995.Furthermore,the RSDs of the precision and repeatability tests were under 6.3%,the coeffecient of recovery was between 87.25%~108.4%.Conclusion This study had established a set of method to detect scientific organophosphorus pesticide residues.It will provide effective guarantee for screen raw broken-rice materials of the injection glucose.

近年来临床上葡糖糖注射液的需求量逐年增大、有供不应求的趋势[1]。目前注射用葡萄糖的生产几乎都是以玉米为原料,经过NOVO法酶解而成。然而对以稻谷为主要农作物的我国而言,玉米的产量并不多。从而使得以玉米为原料生产供注射用葡萄糖的周期长、产量低、成本高[2]。因此,寻求一种供制备注射用葡萄糖的新原料物种已经成为关注的焦点问题。为此,国内许多专家曾试图以大米为原料研制开发供注射用的葡萄糖,但由于以大米为原料的生产成本较高、工序过长等原因而使得其产业停滞不前[3-4]。……
