摘要
Abstract
The gold -loaded carbon samples were dissolved by the nitric acid and sulfuric acid.Car-bon base were removed through the smoke.The arsenic content was determined by the AFS with thiourea -acsorbic acid which turned the AS(5 +)to the AS(3 +).The detection limit of the method was 0.093 g/L, and the relative standard deviations of 5 different amounts of samples were between 1 .59% and 5.52%,the recoveries were in the range of 96% to 1 01 %.关键词
