Spectrophotometric Determination of Ascorbic Acid with Iron(III) and p-Carboxyphenylfluorone in a Cationic Surfactant Micellar Medium

A simple and highly sensitive spectrophotometric method for the determination of ascorbic acid (AA) was established by using iron(III) and p-carboxyphenylfluorone (PCPF) in a cationic surfactant micellar medium. The apparent molar absorptivity of the proposed method, which does not require an extrac...
