本文讨论了铁(Ⅲ)-2-(5＇-溴-2＇-吡啶偶氮)-5-二乙氨基苯酚配合物1.5、2.5阶微分吸附伏安法电流1.5、2.5阶微分峰峰值的表达式。实验结果表明,1.5、2.5阶吸附伏安法的线性范围为1×10~(-10)～1×10~(-7)mol/L,对2.5阶微分吸附伏安法,富集2min的检测下限为5×10~(-11)mol/L。用此法测定了人发中的痕量铁。
In this paper, the 1.5, 2.5 differential micro-voltammetry current peak currents of 1.5 and 2.5 differential peaks were calculated for iron (III) -2- (5’-bromo-2’-pyridylazo) -5-diethylaminophenol complex expression. The experimental results showed that the linear range of 1.5 and 2.5-step sorption voltammetry was 1 × 10 -10 -10 1 -7 mol / L, The detection limit is 5 × 10 ~ (-11) mol / L. Determination of trace iron in human hair by this method.
