- Abstract
We report here in detail the redox properties and catalytic origination of poly(melamine). Gradual change in redox behavior of the monomer from polymer is explained by grafting monomer and different amounts of polymer on screen printed carbon electrode. The redox peak of the poly(melamine) is pH-dependent with a slope of--60 mV/pH, representing a Nernstian type proton-coupled electron-transfer process. Catalytic origination from the -NH-NH- bond formed in polymer is proved using NADH as a probe. This polymer is effective to catalyze NADH oxidation with a wide linear range of 1 µM-10 mM and a detection limit (S/N = 3) of 0.67 µM. Most importantly, unlike most neutral pH active polymer dyes, it shows high stability even after 15 days.
