Background: A new modified electrode based on the poly(chromotropic acid) (4,5-dihy-droxynaphthalene2,7-disulfonic acid) film was developed by electrochemical polymerization to explore its voltammetric behavior. The electrochemical synthesis of poly(chromotropic acid) was accomplished by applying an aqueous solution of sodium hydroxide as a supporting electrolyte (0.1 M). The electrochemical behaviors of bisphenol A (BPA) on poly(chromotropic acid) modified glassy carbon electrode (poly(CTA)/GCE) were researched by cyclic voltammetry, square wave voltammetry, and chronoam-perometry.
