SummaryMembrane based non-dispersive solvent extraction (NDSX) of U(VI) from aqueous nitric acid medium was carried out using a commercial hollow fibre module containing microporous hydrophobic polypropylene capillaries. The NDSX operation was carried out by pumping U(VI) solutions at varying concentrations of nitric acid (1-5 M) through the tube side and organic solvent (di-

BiVO 4 powder was easily prepared from Bi2O3 and V2O5 in an aqueous nitric acid solution at room temperature. The obtained crystal structure depended on the molar ratio of Bi2O3 to V2O5, which is the concentration and volume of an aqueous nitric acid solution. BiVO4 with monoclinic scheelite structure formed using starting materials, in which the molar ratio of Bi2O3 to V2O5 was 1:1. When the molar ratio was 4:3, BiVO4 with tetragonal zircon structure was obtained. Although BiVO4 with monoclinic scheelite structure was platelike particles reflecting the crystal structure, the thickness of the particle increased with an increase in the concentration of an aqueous nitric acid solution. The obtained BiVO4 with monoclinic scheelite structure showed good photocatalytic performances for O2 evolution and methylene blue degradation under visible-light irradiation.

Pyrimidine Derivatives

This study targets the investigation of three pyrimidine derivatives (MA-1230, MA-1231, MA-1232) for the prevention of corrosion on copper in 1 M HNO3via weight loss (WL), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) techniques.
