关于多种配体与相应金属形成螯合物的高效液相色谱(HPLC)研究已有专门综述,但金属-2-(5-溴-吡啶偶氮)-5-二乙氨基酚(5-Br-PADAP)螯合物的HPLC研究报道不多。现有文献中通过一次分离来检测多金属离子的报道较少,特别是在色谱流动相中添加表面活性剂和氯化钠时探讨金属螯合物的色谱保留行为的研究至今尚未见报道。
High performance liquid chromatography (HPLC) studies on the formation of chelates of various ligands with corresponding metals have been reviewed in detail, but the use of 5- (5- bromo-pyridylazo) -5-diethylaminophenol Br-PADAP) chelate HPLC study reported little. However, there are few reports about the detection of metal ions by single separation in the existing literature. The study on the chromatographic retention behavior of metal chelates when surfactants and sodium chloride are added to the chromatographic mobile phase has not been reported so far.
