苏联利用水化学方法找矿已有二十余年的历史,並成为地球化学找矿的一种重要而有效的方法。近几年来該方法于国内亦漸見重视,但因缺乏簡便快速而灵敏的分析方法,因此尚未能普遍展开。一般分析方法需採集大量水样加以蒸发,然后测定干涸殘渣中的微量金屬之含量。如此非但蒸发水样需时甚长,蒸发过程中易致沾污,且因所採集之水样体积龐大(每一样品需一公升以上),故採样时虽付出大量之劳力而所得之样品为数不多。若在野外无条件进行蒸发时則更須展转运輸,常难免保管失当而使水样发生变質、沾污以致结果失真。苏联之水化学工作者曾制定若干天然水中微量金属离子的野外快速测定法及天然水中微量金屬离子的濃集方法。后者
The Soviet Union has used water chemistry to prospect for more than 20 years and has become an important and effective method for prospecting in geochemistry. In recent years, this method has also gained great attention in China. However, due to the lack of a simple, quick and sensitive method of analysis, it has not yet been widely implemented. The general method of analysis requires collecting a large amount of water to evaporate, and then measuring the content of trace metals in the dried up residue. In this case, it takes a long time to evaporate the water sample and is easily contaminated during the evaporation process. Since the water sample collected is bulky (more than one liter for each sample), a large amount of labor is required to sample the sample Not many. If unconditioned in the wild when the evaporation is even more to be transferred to transport, often difficult to avoid improper storage of water samples have metamorphism, contamination resulting in distortion. Water chemists in the Soviet Union have developed a number of rapid determination of trace amounts of metal ions in natural water and concentration of trace metal ions in natural water. the latter
