摘　　要：采用高压密封消化罐 (PTFE) ,以 (4+ 1)硝酸 -高氯酸为溶样试剂 ,采用电感耦合等离子体原子发射光谱法 (ICP- AES)测定黄芪成分 F3新制剂中铁、锰、铜、锌、铬、锶、硒、铅、砷、镉等微量元素。方法回收率为 94 .2 %— 10 6 .3% ,相对标准差为 4 .1%— 7.9%。黄芪成分 F3新制剂含有多种重要微量元素 ,不含有铅、砷、镉等有害元素。The method for the direct determination of 10 trace elements of iron,manganese,c opper,zinc,chromium,strontium,selenium,lead,arsenic,cadmium in new preparation- component F3 of astragalus membranaceus,with(4+1) nitric acid and perchloric ac id as sample dissolution rea gent,and PTFE autoclave,by ICP-AES was proposed.The recovery rate is 94.2%—106 .3% and the relative standard deviation is 4.1%—7.9%.The results are satisfacto ry.There are many important trace elements in new preparation-component F3 of a stragalus membranaceus,without the harmful elements of lead,arsenic,cadmium.
