以氨基G酸偶氮氯膦为显色剂,在溴化十六烷基吡啶存在下,以胶束增溶光度法测定煤中的钍,方法灵敏,ε_(702)=2.31×10~5。取得较好的效果。
The method was sensitive to the determination of thorium in coal by micellar solubilization spectrophotometry in the presence of cetyl pyridinium bromide with amino acid G as chlorophosphonazo reagent, ε 702 = 2.31 × 10 ~ 5 . Achieve better results.
