Abstract
Polymelamine is a new class of polymer that possess electrocatalytic behavior in dopamine (DA) detection. Our previous studies have successfully replaced the conventional acidic electrolyte to deep eutectic solvent (DES) has open the opportunity for a greener solvent in used. Herein we report the optimization process of melamine electropolymerize in DES-reline. Various electrochemical techniques have been employed to studies the ideal parameters. The optimum potential window, scan rate, and number of scan cycles were recorded as-0.20 V – 1.60 V, 50 mV s-1 and five scan cycles, respectively. Cyclic voltammetry (CV) was employed in the electropolymerization of melamine to optimize the redox behavior of polymelamine film on electrode surface. The growing of polymer film which indicated by the increased of reduction current can be well-controlled by the slow scan rate and optimum scan cycles which leads to strong adhesion and uniform morphology. Amperometry sensing on DA was performed to study and compare the sensitivity and limit of detection for the polymers synthesized in varied parameters. A brief discussion on the principal polymerization factors that would affecting the electrocatalytic behavior of melamine is included. © 2022, Malaysian Society of Analytical Sciences.
