依据锆 (IV)对 H2 O2 氧化木立口 花青褪色的催化行为 ,建立了测定痕量锆的催化动力学分析法。本法线性范围为0～ 110 ng/ml,检测限为 0 .4ng/ml。除 Cr( ) ,Cu2 + 和 Fe3+ 外 ,其余离子不影响测定。其干扰可用 EDTA和甘露醇掩蔽消除 ,也可将 Cr( )还原为 Cr( )而消除其影响。测定了锆青铜及合成样品中的锆 ,结果满意。 Based on the catalytic behavior of zirconium (IV) on the fading of cyanobacteria in wood by H2O2, a catalytic kinetic method for the determination of trace zirconium was established. The linear range of this method is 0 ~ 110 ng / ml, the detection limit is 0.4 ng / ml. In addition to Cr (), Cu2 + and Fe3 +, the rest of the ions do not affect the determination. Its interference can be eliminated with EDTA and mannitol masking, but Cr () can also be reduced to Cr () to eliminate its effects. Zirconium bronze and zirconium were synthesized and the results were satisfactory.
