摘要:
在4×10-5mol/L ZCO-0.4mol/L NH4Cl-0.6%Na2SO3溶液中,钢(Ⅱ)-ZCO与铁(Ⅱ)-ZCO络合物在单扫描示波极谱仪上可观察到两个灵敏的极谱吸附波,峰电位分别为—0.63V和—0.76V(vs.SCE),峰电流与钢(Ⅱ)铁(Ⅱ)浓度分别在1.3×10-7—2.5×10-5mol/L和3.0×10-7—3.0×10-5mol/L范围内呈线性关系,检测限分别为7.8×10-8mol/L、1.5×10-7mol/L.本文研究了产生钢、铁波的条件,探讨了波的性质、测定出铜(Ⅱ)、
Abstract:
By single-sweep polarography of the solution consisted of 4×10-5mol/L ZCO,0. 4 mol/L NH4Cl and 0.6% Na2SO3,two sensitive polarographic adsorption waves of the com- plexes of Cu-Zincon and Fe-Zincon can be observed,with respective peak potential at—0.63 V
