| Abstract: | The samples are decomposed by aqua regia, that is, adding some molysite in 10% aqua regia solution, the Au in the samples will be absorbed by the polyaminoester foamed plastics. Then it is disembarrssed by 1% thiourea solution and determined by ICP-MS. It has been found that the determination has higher precision, better accuracy and lower detection limit, the measurement range 0.028 - 500ng/g. |
