Simultaneous/selective volatmetric detection of diclofenac and tetracycline in water on graphene modified boron-doped diamond electrode

The graphene oxide modified boron-doped diamond electrode (GO/BDD) was obtained electrochemically and tested by cyclic voltammetry (CV) to detect diclofenac (DCF) from anti-inflammatory pharmaceuticals class and tetracycline (TC) from antibiotics one, which belongs to emerging pollutants from water. Graphene reduced electrochemically from its oxide showed enhanced sensitivity in determining individual and selective or simultaneous of DCF and TC. The cyclic voltammetry method - based protocol for selective/simultaneous detection of DCF and TC was developed in this study using a commercial boron-doped diamond (BDD) electrode modified with graphene oxide (GO).
