TL;DR: In this article, a comprehensive discussion is presented of the basic views and quantitative expressions which are needed to understand the influence of adsorption of electroactive species on the shapes of the waves in d.c. polarography, a.k.a. linear sweep voltammetry.

TL;DR: In this paper, the authors proposed a method for the polarographic reduction of five triazinyl azo dyes differing only in their potentially reactive group, and optimum conditions were given for their polarographic and voltammetric determination.

TL;DR: In this paper, the voltage-metric behavior of methotrexate (MTX) was investigated using electrochemical methods, such as cyclic voltammetry, direct current voltammetric, and differential pulse voltage-ammetry on a mercury meniscus modified silver solid amalgam electrode (m-AgSAE), and the optimal conditions for its determination have been found in a Britton-Robinson buffer of pH 5 with the limit of detection equal to 1.8
Abstract: Voltammetric behavior of methotrexate (MTX), an important chemotherapeutic drug, has been investigated using electrochemical methods: cyclic voltammetry, direct current voltammetry and differential pulse voltammetry on a mercury meniscus modified silver solid amalgam electrode (m-AgSAE). The obtained results have been compared with those obtained using a hanging mercury drop electrode (HMDE). The optimal conditions for its determination have been found in a Britton-Robinson buffer of pH 5 with the limit of detection equal to 1.8 nM. RSD at this concentration level amounted to less than 4 %. The proposed procedure of determination was verified on a real drug containing MTX.

TL;DR: In this article, different concentrations of non-specifically and specifically adsorbed supporting electrolytes were employed to change the potential φd at the outer Helmholtz plane and/or the charge density qi at the inner Helm-holtz planes.
