【摘要】 <正> DBC—偶氮胂是新型的显色剂,化学名称为2-(2-胂酸基苯偶氮)-7-(4-氯,2,6—二溴)—1.8—二羟基-3,6-二磺酸萘。简称DBC,其结构式:

【Abstract】 In this paper a new colour reagent Dibromo-Chloro-arsenazo (DBC) for the spectrophotometric determination of thorium was investigated. It has been found that Th-DBC. Complex is stable, rapid developing, high sensitive and selective. In our experiment, ion exchange chromatography was used for separation and successive determination of thorium and light rare-earth in Rare-Earth ore. The results obtained were satisfactory.
