摘要
本文采用金试剂[4.4′—双(二乙氨基)二苯甲硫酮]为显色剂,磷酸三丁酯(TBP)为萃取剂,研制了液珠萃取比色新方法。方法检测范围0.5～10000ppb。
A new colorimetric determination of trace gold is developed with liquid ball extraction using 4,4'-bis (diethylamino) diphenyl methylthioketone as a chromophoric reagent and tributylphosphate as an extractant. Detectable limit is 0.5-10000 ppb.
