Abstract:Abstract. In this paper, we prepared poly para aminobenzoic acid (PABA) membrane on a glassy carbon electrode (GCE) using cyclic voltammetry(CV) following electrochemically degrading to form a porous PABA (PPABA) membrane. The PPABA membrane was characterized using CV technique, scanning electron microscope (SEM) measurements. The PPABA membrane could improve sensitivity of dopamine (DA) and inhibit ascorbic acid (AA) and uric acid (UA) electrochemical oxidation. The PPABA/GCE-based electrohemical sensor displ… Show more
