The electrochem. behavior of Alizarin Red S (I) on a glassy carbon electrode was studied in acidic solution by spectroelectrochem. method. There were 3 electrochem. reactions followed by a chem. reaction of I in the potential range of 0.60-1.00 V. The mechanism of the electrode reactions was discussed based on the information obtained from electrochem. and in-situ spectroelectrochem. experiments
