| Abstract: | After dissoluting the samples by agua regia, the Trace silver is separated and concentrated in the medium of 5-15% agua regia with foam plastics. The silver adsorbed on the plastics is desorb ed by 2%thiourea solution, then the silver desorbed is determined by ICP-AES.The recovery is 97.60-100.20%. the detection limit of proposed method is 0.020lX10-8.The advantages of this method are less interferences, better accuracy, and more rapid and simple to operate. |
