研究了双 (6-氧 -丁烯二酸单酯 ) -β-环糊精 (简称β- CD衍生物 )对 Pd( ) - 2 - (5-溴 - 2 -吡啶偶氮 ) - 5-二乙氨基苯酚 (简称 Pd( ) - 5- Br- PADAP)显色反应的增敏作用。在 p H=4.0～ 5.0的 HAc- Na Ac介质中 ,该体系最大吸收波长为 590 nm,表观摩尔吸光系数为 6.71× 1 0 4 L· mol-1· cm-1,钯 ( )含量在0～ 1 1 μg/1 0 m L范围内服从比尔定律。方法用于活性炭载体催化剂和矿样中钯的测定
The effects of Pd (superscript 2 - (5 - bromo - 2 - pyridylazo) - 5- Sensitizing Effect of Diethyl Aminophenol (Pd () - 5 - Br - PADAP) for Color Reaction. In HAc-Na Ac medium with pH = 4.0 ~ 5.0, the maximum absorption wavelength of the system is 590 nm, the apparent molar absorptivity is 6.71 × 104 L · mol-1 · cm-1, Beer’s law is obeyed in the range of 0-1 1 μg / 1 0 m L. Method for the determination of palladium in activated carbon supported catalysts and mineral samples
