关于泡塑对金的捕集特性研究,1976年国内已用于金的测定,而泡塑富集光谱测定微量金的方法,作者已有报导。分析实践表明:从0.01—65.0克/吨的范围内方法是可靠的。几年来,由于方法的不断完善,1克/吨金样的测定相对标准偏差由最初的18.5％下降至11.8％。 化探的发展,使ppb级痕量金分析成为紧迫需要。文献为解决上述课题取得了关键性的突破。资料号称具有了纳克检出限,但方法繁琐。作者设计了一个简便的 On the plastic foam on the trapping characteristics of gold, in 1976 the country has been used for the determination of gold, while the bubble enrichment spectrometry trace gold method, the authors have been reported. Analytical practice shows that the method is reliable from 0.01-65.0 g / t. In recent years, the relative standard deviation of the 1 g / ton gold sample has decreased from 18.5% to 11.8% due to the continuous improvement of the method. The development of geochemical exploration makes ppb-level trace gold analysis an urgent need. Literature to solve the above problems made a key breakthrough. The material claims to have a nanogram detection limit, but the method is tedious. The author designed a handy
