摘要
在8×10^(-3)mol/L NaOH-0.2mol/L KClO_3底液中,Pb(Ⅱ)-QBTU体系产生灵敏的阴极化二阶导数波,峰电流与铅浓度在4.0×10^(-8)～4.5×10^(-6)mol/L范围内有良好的线性关系。本文对电极过程,反应机理,极谱波的性质进行了详细的探讨。
In a medium of 8×10^(-3)mol/L NaOH-0. 2 mol/L KC1O_3, Pb-N-(8-quinolyl)-N＇-benoylthiourea(GBTU) complex gave a sensitive cathodic second derivative complex adsorption wave. The peak current of the second derivative wave is linearly proportional to the concentration for lead in the range of 4. 0×10^(-8～4. 5×10^(-6) mol/L. The electrode process, reaction mechanism and polarographic behavior have been discussed in detail.
