Abstract

Abstract

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.
