Modification of carbon paste electrode by electrochemical polymerization of neutral red and its catalytic capability towards the simultaneous determination of catechol and hydroquinone: A voltammetric study

The poly (neutral red) modified carbon paste electrode (PNR/MCPE) was developed by electropolymerization method and applied for the simultaneous determination of catechol (CC) and hydroquinone (HQ) in presence of 0.2 M phosphate buffer solution (PBS) at pH 7.4 with the scan rate of 50 mV s− 1.106
