【Abstract】 A method for the direct determination of 10 trance elements of iron,manganese, copper, zinc, chromium, strontium, selenium, lead, arsenic, cadmium, in a new preparation component F3 of astragalus membranaceus is proposed. The method is to use (4+1) nitric acid and perchloric acid as a sample dissolution reagent, and PTFE autoclave by ICP-AES. The results reveal that the recovery rate is 94%～106% and the relative standard deviation is 4.1～7.9%. The results are satisfactory. Then the conclusion is that there are many important trance elements in new preparation component F3,and does not exist harmful elements of lead, arsenic, and cadmium.更多还原
