中文摘要:
      目的 建立鸡血藤中铬、铜、砷、镉、汞、铅6种重金属的含量测定方法。方法 采用微波消解法前处理样品,ICP-MS同时测定鸡血藤中6种重金属的含量,并参照WHO标准对其最大理论限量进行评估。结果 6种待测元素在各自的线性范围内线性关系良好(r≥0.9998),方法检测限为0.0016~0.0227mg/L,平均回收率在70.05%~117.98%,RSD在1.30%~3.69%,样品中铬、铜、砷、镉、汞、铅6种元素的平均含量均小于其最大理论限量值(0.8000、140.0、0.8571、0.4000、0.2286、1.429mg/kg)。结论 方法简单、准确、灵敏度高,可为鸡血藤中重金属元素的测定和限量评估提供参考。
英文摘要:
      OBJECTIVE To develop a method for the determination of 6 hazard elements such as Cr, Cu, As, Cd, Hg and Pb in Spatholobi Caulis. METHODS After the microwave digestion and then 6 hazard elements were determined by ICP-MS at the same time. Based on this, the limit of Cr, Cu, As, Cd, Hg and Pb were assessed with WHO standards. RESULTS The determination results of 6 hazard elements all have a good linear relationship, r≥0.9998. The limit of detection was range from 0.0016~0.0227ng/mL, the average recovery was 70.05%~117.98%, and RSD were 1.30%~3.69%. Determination results of samples of 6 hazard elements less than the maximum limit value(0.8000, 140.0, 0.8571, 0.4000, 0.2286, 1.429mg/kg). CONCLUSION The method is simple, accurate and high sensitive, can be used for the quality control and limit assessment of Spatholobi Caulis.
