The development of a miniaturized electrochemical cell to be applied to didactical experiments involving cyclic voltammetry is presented. The main objective is proposing an experiment for undergraduate courses within the concepts of Green Analytical Chemistry and involves the learning of electrochemistry and analytical chemistry concepts. The electroanalytical techniques are examples of "green" practices analysis once they usually employ small solution volumes, presenting at the same time high sensitivity and are easily miniaturized and automated. Thus, the understanding of electrochemical concepts is of great importance to students offering them, environmentally friendly didactical experiments using alternative and low cost materials, which is extremely welcome. In this context, this work demonstrates that a miniaturized electrochemical cell constructed with micropipette tips can be successfully used to study reversible electron transfer processes by cyclic voltammetry. The proposed electrochemical cell not only has the same performance of a conventional-size electrochemical cell but also brings a remarkable decreasing on chemicals consumption and residue generation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
