摘要：

The electropolymerized film of amaranth was prepared on the surface of graphite pencil electrode (GPE) using cyclic voltammetric technique. This poly(amaranth) film coated electrode exhibited an excellent electrocatalytic activity towards the detection of dopamine (DA) in the presence of uric acid (UA) in 0.2 mol/L phosphate buffer solution at pH 7.0. The effect of interference study was carried out using differential pulse voltammetric technique. The poly(amaranth) modified GPE was applied for the detection of DA in dopamine injection with satisfactory results. (C) 2010 B.E. Kumara Swamy.
