粉末法光谱定量测定矿石中低含量锡的方法很多,但我们所遇到的含氟碳酸盐和硼矿中锡的选矿样品测定,现行办法都不适应。为此,根据矿区矿样的成份,制定合适的工作条件。以无水碳酸钠、三氧化二铝和三氧化二锑的混合物作缓冲剂,锗为内标,交流电弧激发,中型石英光谱仪摄谱,测定0.01～1%的二氧化锡,其测定相对均方误差精矿为2.8%,尾
There are many methods for the quantitative determination of tin in ore by powder spectrometry. However, the methods we have encountered for the determination of tin in flotation of fluorocarbons and boron in boron do not fit the current methods. To this end, according to the composition of mine samples, to develop appropriate working conditions. An aqueous sodium carbonate, aluminum oxide and antimony trioxide mixture as a buffer, germanium as an internal standard, alternating current arc excitation, medium-sized quartz spectrometer spectroscopy determination of 0.01 to 1% of the tin dioxide, the determination of the relative average Square error of 2.8%, tail
