土壤、水系沉积物、岩石矿物中超痕量铂的测定

Determination of Ultra-trace Platinum in Soil,Water Sediment and Rock Minerals

针对土壤,水系沉积物以及岩石矿物当中所含的超痕量铂的比例以及数量进行了具体测定方法的研究。其中,最主要也是最准确的微量元素的测定方法,就是可以通过湿法分解这种方式进行测定,在土壤,水系沉积物以及岩石矿物当中加入一些氯化亚锡成分,氯化亚锡可以有效地将微量元素进行分离以及提取,并且氯化亚锡可以和铂形成结合离子,这样能够有效地被活性炭吸附,从而更快地促进分解。在进行分离和集合之后,可以采取快速曝光技术,发现所需要测定的元素种类当中所蕴含的铂离子的具体数量。通过分析检测以及相关的化学成分测定,以有效地减少偏差,最大程度将测量结果控制在合理范围内。不仅符合测定程序,而且能够符合国家的检定质量标准。

Aiming at the proportion and quantity of ultra-trace platinum in soil,water sediments and rock minerals,this paper has carried out research on specific measurement methods.The most important and most accurate method for determining trace elements is to measure it by wet decomposition.Adding stannous chloride to the soil,water sediments and rock minerals,stannous chloride can be effective The trace elements are separated and extracted,and stannous chloride can form binding ions with platinum,which can be effectively adsorbed by activated carbon,thereby promoting decomposition faster.After separation and assembly,a rapid exposure technique can be adopted to discover the specific amount of platinum ions contained in the element types to be determined.Through analysis and detection,and related chemical components,the purpose of the measurement,in order to effectively reduce the deviation,try to control the measurement results within a reasonable range.Not only meet the determination procedures,but also meet the national quality standards for verification.
