辉锑矿Sb_2S_3,主要成分为Sb(71％),S(28％),伴生有微量As、Cu、Pb、Zn、Sn、Bi、Ag等元素。 锑的大量存在及锑化物在酸度低时容易水解,常给其他项目的分析带来困难,一般分离手续麻烦。本文采用在石墨坩埚内以盐酸-氢溴酸分解样品并挥发除锑、碱熔后制备成5％盐酸溶液。可测定铜、铅、锌、银、硅、铁、铝,钛、钙、镁、锰等元素。单独 The stibnite Sb2S_3 is mainly composed of Sb (71%) and S (28%) with trace amounts of As, Cu, Pb, Zn, Sn, Bi and Ag. The presence of a large amount of antimony and antimony compounds in the low acidity easily hydrolyzed, often difficult to analyze other projects, the general separation procedures trouble. In this paper, hydrochloric acid-hydrobromic acid is used in the crucible to decompose the sample and volatilize except antimony. After alkali melting, a 5% hydrochloric acid solution is prepared. Can be determined copper, lead, zinc, silver, silicon, iron, aluminum, titanium, calcium, magnesium, manganese and other elements. alone
