This study describes the robust modification of a screen-printed carbon electrode (SPE) for magneto-electrochemical determination Mn2+, in real soil samples, by square wave cathodic stripping voltammetry (SW-CSV). The surface SPE was modified with electrodeposited Au, then dropcast Fe3O4 NPs functionalised l-cysteine within graphene oxide matrix. magnetic significantly increased diffusion coeff...

Abstract The aim of this study was to develop an analytical method determine free concentrations Europium (Eu(III)) in natural waters. Europium(III) solution detected using cathodic stripping voltammetry after complexation with N -nitroso- -phenylhydroxylamine (cupferron). Optimization parameters allowed us detect nanomolar levels Eu(III) solution. Free measured the Donnan membrane technique wh...

Recent progress in the theory and practice of voltammetry is surveyed and evaluated. The transformation over the last decade of the level of modelling and simulation of experiments has realised major advances such that electrochemical techniques can be fully developed and applied to real chemical problems of distinct complexity. This review focuses on the topic areas of: multistep electrochemic...
