Assessing the electrochemical sensing behavior of manganese based inverse spinel towards ascorbic acid detection

In this research article, a non-enzymatic electrochemical ascorbic acid (AA) sensor using inverse spinel of manganese cobaltite (MCO) stabilized on GCE was evaluated. Investigation on the characteristics of the syn-thesized manganese cobaltite nanoparticles were acquired from XRD, UV, XPS, FTIR, SEM, and TEM charac-terization techniques. The principal results observed include, two linear ranges in the sensor's dynamic range of detection from 5 mu M -1.5 mM and 1.5-4.44 mM with LOD and LOQ of 0.085 mu M and 0.283 mu M respectively. The anti-interference study indicated a restoration of 107.4% and 91.3% recovery amidst biological and tablet excipient molecules respectively. The recovery results obtained from the biological and pharmaceutical samples conclude a satisfactory validation of recovery from pharmaceutical samples of Vitamin-C tablets and drinks.
