摘要
研究了在盐酸存在条件下,锆(IV)与显色剂 2,4 二羟基苯乙酮苯甲酰腙(DHAPBH)及二甲酚橙(XO)形成混合物的显色反应。在浓度为 4.0 mol/L的 HCl介质中,锆与二甲酚橙、2,4 二羟基苯乙酮苯甲酰腙形成紫红色配合物,其λ=543 nm,表观摩尔吸光系数ε=9.2×104 L·mol-1·cm-1。考察了20余种离子的干扰情况,并在干扰离子存在下测定了3组混合溶液,结果均较满意。
The colour reaction of zirconium(IV) with xylene orange and 2,4-dihydroxy- acetophenone benzoylhydrazone in the media of HCl has been studied. Zirconium(IV) reacts with xylene orange and 2,4-dihydroxyacetophenone benzoylhydrazone to form a complex with maximum absorption at 552 nm when HCl concentration is 4.0 mol/L. The apparent molar absorptivity is 9.2×10^(4) L·mol^(-1)· cm^(-1). More 20 coexistence ions are not disturbance to determined. This method has been applied to determinate zirconium(IV) in mixture containing coexistence ions, the result is satisfactory.
