Electrochemical Studies of Mesalazine at Sodium Dodecyl Sulfate Modified Carbon Paste Electrode: A Cyclic Voltammetric Study

The electrochemical studies of mesalazine was performed at sodium dodecyl sulfate modified carbon paste electrode by cyclic voltammetric technique in 0.2 M phosphate buffer solution at pH 7.2 with a scan rate 100 mV/s. Sodium dodecyl sulfate modified carbon paste electrode showed an enhanced current signal as compared to the bare carbon paste electrode. Electrochemical parameters like effect of pH, scan rate and different concentration of mesalazine were investigated at sodium dodecyl sulfate modified carbon paste electrode. The effects of scan rate study revealed that the overall electrode process was found to be adsorption controlled processes at sodium dodecyl sulfate modified carbon paste electrode. The detection limit of mesalazine was found to be 0.238 μM.
