Bromo-PADAP is a dye agent for research use. Bromo-PADAP was reported for the spectrophotometric determination of uranium(VI). Bromo-PADAP is highly sensitive towards uranium, the uranyl complex having a molar absorptivity of 74,000 at 578 nm and pH 7.6. In the presence of a mixed masking solution only a few ions interfere seriously, and the method can be made specific for uranium by a preliminary extraction of uranium into tri-n-octylphosphine oxide, and direct development of the bromo-PADAP colour in the organic phase. Details are given for the determination of uranium in waters, ores, phosphoric acid and phosphate rocks, thorium oxide, and zirconium oxide.
