Abstract
A dimensionless analysis for the limiting current in normal pulse polarogra phy (NPP) with reactant adsorption obeying the Langmuir and the Frumkin iso therms is presented. Zone diagrams, calculated numerically with reference t o limiting cases which can be approached by analytical expressions, allow t he determination of the adsorption parameters. Conclusions concerning the i nitial accumulation of the adsorbate at zero current, apply to other voltam metries. (C) 1999 Elsevier Science S.A. All rights reserved.
