摘要
采用样品与试剂混合,直接在灰皿中进行熔融、灰吹,合粒用硝酸分解,火试金法测定树脂中的金。实验结果表明,该方法对测定树脂中的金具有较好的准确度,相对标准偏差为1.27%。
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%.
