| 摘要: |
| 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. Methods 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. |
