摘要
系统研究了铌（V）与氯代磺酚S的显色反应，优化了反应条件．考察了该显色体系的分析性能，研究了样品的分解方法，拟定了用光度法分析包头铁矿及其冶炼渣中铌的方案．
The colour reachon of niobium(V) and sulfochlorophenol S has been system-atically investigated.The condihons of the reachons were optimized and analytical character-istics of this colour system were examined. A decomposition method of the samples was studied and the spectrophotometry for determination of niobium in Baotou iron and its slags was developed.
