The electrochemical detection of tetrabromobis-phenol A (TBBPA) with boron-doped diamond (BDD) thin film electrode is demonstrated. The electrode is synthesized by filament-assisted chemical vapor deposition. An irreversible oxidation peak is observed for TBBPA in phosphate buffer on BDD surface. A method to renew the electrode is developed by sweeping in H2SO4 at 3V for 100s first and at −3V for...
This paper presents the fabrication, characterization and application of PEDOT-ionic liquid composite films modified Au microelectrodes. Here only one-step electropolymerization was required for the preparation of PEDOT-BMIMBF4 and PEDOT-BMIMPF6 composite films, which were investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), scanning electron microscope (SEM), and...
In this work, an ultra-violet (UV) photocatalysis method in the presence of H2O2 utilizing nano-TiO2 photocatalyst is presented for the digestion of total phosphorus (TP) in water. The UV digestion of 4 mg/L of sodium glycerophosphate solutions (by weight of P) were conducted at different digestion time and concentrations of H2O2. The H2O2 added to the water samples could increase the formation rate...
