英文摘要	A polymerized film of 35-dihydroxy benzoic acid (dba) was prepared on the surface of a glassy carbon electrode (gce) in neutral solution by cyclic voltammetry (cv). the poly(dba) film-coated gce exhibited excellent electrocatalytic activity toward the oxidation of dopamine (da). a linear range of 1.0 x 10(-7) to 1.0 x 10(-4) m and a detection limit of 6.0 x 10(-8) m were observed in ph 7.4 phosphate buffer solutions. moreover, the interference of ascorbic acid (aa) was effectively eliminated. this work provides a simple and easy approach to selective detection of da in the presence of aa.
