前言多种不同的采样介质已被广泛应用于金和伴生元素的勘查,其中生物地球化学研究方面包括植物、腐殖质及泥炭样品的分析。地球化学采样包括采集水系沉积物、土壤及岩石样品以及地下水或雪水等水地球化学研究。对于各种不同的研究,必然会增加火试金法、极谱法以及不经预浓缩处理的原子吸收光谱法等金分析方法所固有的困难。因为上述方法没有一种是特别灵敏的。金的中子活化分析技术的推广,为金提供了一种精
Preface A variety of different sampling media have been widely used in the exploration of gold and associated elements, including the analysis of biogeochemical research including plant, humus and peat samples. Geochemical sampling includes collecting water sediments, soil and rock samples, and water geochemical studies such as groundwater or snow water. For a variety of different studies, it is inevitable to increase the difficulties inherent in gold analysis methods, such as fire assay, polarography, and atomic absorption spectrometry without preconcentration. Because none of the above methods are particularly sensitive. The promotion of gold neutron activation analysis technology has provided gold with a fine
