摘要
作者对在0.02mol/l柠檬酸三钠底液中、pH=6.1、Pb-PR络合物吸附波进行了研究,并测定其线性范围,应用于微量铅的测定,其方法回收率在95～104%。
Lead and pyrogallol red complex produces a sensitive polarographic adsorptive wave etpH=6,1 in 0.02M sodium citrate, The peak current is linear to the concentration of pb in therange of 9.7×10^(-7)～1.4×10^(-5)M. The method is accurate and rapid. The properties of this wavehas been studied.
