借碘化铵灼烧使锡成碘化锡挥发的定量测定锡的方法,近来已有文献介绍。我们在锡石铌钽矿物分析方法的基础上,进行了锡石单矿物的测定。样品经碘化铵灼烧定量测定氧化锡以后,用焦硫酸钾熔融,酒石酸提取,分取滤液测定铌、钽、铁、钛、锰和磷等。我们在酒石酸和铌钽存在下,对测定铁、
The method of quantitative determination of tin by the burning of iodine iodide to tin iodide volatilization has been recently introduced. Based on the analysis method of niobium and tantalum in Cassiterite, we have carried out the determination of the single-mineral of cassiterite. After the sample was quantitatively determined by burning with ammonium iodide, tin oxide was melted with potassium pyrosulfate and extracted with tartaric acid. The filtrate was filtered to determine niobium, tantalum, iron, titanium, manganese and phosphorus. We in the presence of tartaric acid and niobium tantalum, the determination of iron,
