Emerging investigator series: Carbon electrodes are effective for the detection and reduction of hexavalent chromium in water

© 2020 The Royal Society of Chemistry. Electrochemical methods are an attractive option for the detection and reduction of toxic Cr(vi) to benign Cr(iii) in drinking water. Here a method is reported for the reproducible detection and reduction of hexavalent chromium in water on glassy carbon electrodes, over a wide range of pH. This study allows for unmodified inexpensive carbon electrodes to join gold and gold modified electrodes as substrates for Cr(vi) removal from water
