锌和镉在地球化学普查找矿中都是重要的指示元素,随着化探找矿方法的发展和需要,本文对锌和镉进行了研究,并拟出适宜于矿物、岩石、土壤等定量分析方法,其特点是不需任何分离,一份溶液可一次同时测定锌和镉,既简便、快速、高效,且具有捡出限高的优点。检出限分别为:镉0.0003微克/毫升;锌0.0015微克/毫升;相对平均偏差:镉0.85％,锌0.56％,测量范围0.00005～10％。经一批生产检验的结果表明,不仅精密度高,而且在矿体周围出现清晰的异常,效果十分明显,这是很好的分析手段。
Zinc and cadmium are both important indicator elements in general prospecting for geochemical exploration. With the development and needs of geochemical prospecting method, zinc and cadmium have been studied in this paper, and suitable for mineral, rock, soil and other quantitative Analysis method, which is characterized by no need for any separation, a solution can be simultaneously determined at the same time zinc and cadmium, both simple, fast and efficient, and has the advantages of high limit of detection. The detection limits were: cadmium 0.0003 μg / ml; zinc 0.0015 μg / ml; relative average deviation: cadmium 0.85%, zinc 0.56%, the measurement range 0.00005 ~ 10%. The result of a batch of production tests shows that not only the high precision but also the clear abnormality around the orebody is obvious and the result is very good.
