二硫代二安替比林甲烷应用于光度法测定铋早有报道。等继又提出了萃取Bi(Ⅲ)—A(A系电负性配位基)缔合物进入有机相进行光度法测定的方案。此法不但选择性好,灵敏度亦得到提高。
Spectrophotometric determination of bismuth with dithio-diantipyrylmethane has long been reported. Following the proposal of the extraction of Bi (III) -A (A series of electronegativity ligands) association into the organic phase for spectrophotometric determination of the program. This method is not only good selectivity, sensitivity has also been improved.
