摘要
本文系统地评述了天然水中痕量超痕量金的分析。对天然水中金的分布及形态、天然水样的采集及贮存以及对包括蒸发、溶剂萃取、共沉淀、离子交换与吸附、电化学、泡沫浮选等分离富集手段和不同测定方法的应用特点作了全面总结。指出了天然水中痕量超痕量金的分析在水地球化学直接找金法中的地位和作用,并对其发展前景作了展望。全文收集参考文献150篇。
The general aspects in the determination of trace and ultra trace gold in natural water are reviewed. The gold distribution tnd form in natural water, the sampling and preservation of water, the features of various determinatin methods and the enrichment techniques including evaporation, solvent extraction, co-precipitation, ion exchange and sorption, electrochemical deposition and froth flotation are discussed, The status and important roles played by this determination method in gcochemical prospecting for gold are described also.The 150 references are cited.
