| Abstract: | First,composite reagent was mixed with samples,and then we directly put the mixture in the magnesite-made container to be melted.The combined granules were decomposed by nitric acid and the weight method was used to determine gold in resin.The results show that this method has high accuracy and precision.And the RSD is 1.27%. |
