This experiment is designed for senior undergraduate students in an inorganic chemistry course. Students are asked to synthesize a sonogel-carbon electrode that is modified with a ZrO2 sol-gel and to compare the results to those of an unmodified electrode for the detection of phenol. The website is available here .
This labware module contains directions for seven experiments in analytical electrochemistry. The experiments are designed to illustrate fundamentals of electrode reactions as applied to readily accessible redox reactants. They provide insight to dynamic electrochemistry for scientists at all levels of training. Activation procedures to prepare glassy carbon electrodes are provided in a TechNote. The website is available…
Synthesis of a Sonogel-Carbon Modified Sensor Electrode with Titanium Oxide (TiO2) to Detect Catechol
This experiment demonstrates cyclic voltammetry, surface modification, selectivity, and bioanalysis in assaying catechols in the presence of ascorbic acid. Pre- or post-lab questions are included, along with sample student data and instructor's notes. The website is available here .
Analysis of paint helps establish authenticity or works of art. This laboratory experiment, still under development, helps students put measurements in context. The linked discussion forum will allow readers and the author to collaborate in improving the experiment.The website is available here .
This ASDL online article describes a lab experiment whereby students learn how to prepare a conducting thin-film polymer electrode for the analysis of catechol and the effect of ascorbic acid on the cyclic voltammetric results. The website is available here .
