本文介绍了用化学X射线荧光光谱测定矿石中银的方法。王水分解试样,在盐酸介质中,以氯化亚锡为还原剂,碲作共沉淀剂富集试样中的银,将沉淀抽滤至圆滤纸片上进行X射线荧光光谱分析,方法具有快速,简便,灵敏及不受基体变化影响等优点,基本适用于各种矿石及选冶样中0.x～xxx克/吨银的测定。
This article describes a method for the determination of silver in ores using chemical X-ray fluorescence spectrometry. Wang water sample decomposition, in hydrochloric acid medium, stannous chloride as a reducing agent, tellurium as coprecipitation agent enrichment of silver in the sample, the precipitate was suction filtered on a round-leaf filter for X-ray fluorescence spectrometry, the method has Fast, simple, sensitive and not affected by changes in the substrate, etc., is basically applicable to all kinds of ores and metallurgical sample 0.x ~ xxx g / tonne silver determination.
