Bromo-PADAP 是一种用于研究的染料剂。该化合物用于铀(VI)的分光光度测定。Bromo-PADAP 对铀具有高灵敏度,其铀酰络合物在578 nm和pH 7.6条件下的摩尔吸光系数为74,000。在混合掩蔽溶液的存在下,仅有少数离子会严重干扰,通过将铀初步提取到三辛基膦氧化物中,并在有机相中直接展开Bromo-PADAP颜色的发展,可使该方法具体针对铀。文中提供了在水、矿石、磷酸和磷酸盐岩石、氧化钍及氧化锆中测定铀的详细方法。

产品描述 | Bromo-PADAP is a dye agent utilized in research for the spectrophotometric determination of uranium(VI). This compound exhibits high sensitivity to uranium, with a molar absorptivity of its uranyl complex at 74,000 at 578 nm and pH 7.6. In the presence of mixed masking solutions, only a few ions cause significant interference. By initially extracting uranium into trioctylphosphine oxide and subsequently developing the Bromo-PADAP color in the organic phase, the method becomes specifically targeted to uranium. Detailed procedures for the determination of uranium in water, ores, phosphoric acid and phosphate rocks, thorium oxide, and zirconium oxide are provided in the text. |
