研究了1-(5-溴-2-吡啶偶氮)-2-萘酚-6-磺酸与钴(Ⅱ)和镍(Ⅱ)之螯合物的衍生和液相色谱分离条件。于Zorbax ODS柱上,用含0.01mol/L HAC-NaAc(pH 5.5)的乙腈-四氢呋喃-水(24:5:71,V/V)作流动相,流速0.7ml/min淋洗,于570nm检测。本方法已用于镍矿、催化剂回收液和人发样品的分析。
The conditions for the derivatization and liquid chromatography separation of chelates of cobalt (Ⅱ) and nickel (Ⅱ) with 1- (5-bromo-2-pyridylazo) -2-naphthol-6-sulfonic acid were studied. Acetonitrile-tetrahydrofuran-water (24: 5: 71, V / V) containing 0.01 mol / L HAC-NaAc (pH 5.5) was used as a mobile phase on a Zorbax ODS column at a flow rate of 0.7 ml / min. Detection. This method has been used for the analysis of nickel ore, catalyst recovery liquid and human hair samples.
