随着科研工作的发展,近年来对金的湿法分析,已有了不少的研究和报导。这些研究工作提供的数据证明,对于在测定金的过程中减少笨重的体力劳动和公害不但是可能的,而且也是行之有效的。因此,对金的测定,尤其是在国内,有用湿法分析逐步代替火试金的趋向。我们的试验对象主要是铅、铜阳极泥及精选产品,含金量约1000克/吨左右,或更高一些,对于如此含量范围的样品,应用现有的原子吸收法,由于稀释倍数较大,在测定结果的准确性上就会发生困难;另外,这类样品中铅、银等有色金属
With the development of scientific research, wet analysis of gold in recent years, there have been many studies and reports. The data provided in these studies demonstrate that it is not only possible but also effective in reducing cumbersome manual labor and pollution in the process of determining gold. Therefore, the determination of gold, especially in China, a useful wet analysis gradually replace the tendency of fire test gold. Our test objects mainly lead, copper anode mud and selected products, the gold content of about 1000 g / t or so, for such a range of samples, the use of existing atomic absorption method, the larger dilution factor, In the determination of the accuracy of the results will be difficult; In addition, such samples of lead, silver and other non-ferrous metals
