O 引言 在地球化学探矿研究中,往往需要同时了解大批样品中锡钨钼的含量。过去,一般将锡与钨钼分别熔样,分别测定,而一次熔样分别测定的方法因受到特殊仪器及高的锡钨检测限的限制而难以应用。作者结合化探样品分析,提出了一次熔样,加入混合试剂快速测定锡 O Introduction In geochemical prospecting, it is often necessary to simultaneously understand the contents of tin, tungsten and molybdenum in a large number of samples. In the past, tin and tungsten and molybdenum were generally respectively melted and measured separately. However, the methods for determining the primary melting samples were difficult to apply due to the limitations of the special instruments and high detection limits of tin and tungsten. Based on the analysis of geochemical exploration samples, the author proposed a melting sample, adding mixed reagents to quickly determine tin
