Abstract This study describes a simple, high-yield, rapid, and inexpensive route for the synthesis of cubic shape-like cerium oxide nanocubes (CeO2 NCs) using different urea concentrations (0.5, 1.0, and 2.0 g) by the hydrothermal method. The synthesized nanocubes (NCs) are labeled as CeO2 NCs-0.5, CeO2 NCs-1.0, and CeO2 NCs-2.0, corresponding to 0.5, 1.0, and 2.0 g of urea, respectively. The synthesized NCs were characterized by FT-IR, UV-visible, XRD, XPS, SEM and HR-TEM analysis. The synthesized NCs were cubic in shape with average sizes of 12, 12, and 13 nm for the CeO2 NCs-0.5, CeO2 NCs-1.0, and CeO2 NCs-2.0, respectively, obtained by the XRD analysis. The catalytic activity of the CeO2 NCs was studied for the purpose of obtaining the reduction of malachite green (MG) in the presence of sodium borohydride (NaBH4) at room temperature.

Work Up

The effective and efficient removal of the BF2 moiety from F-BODIPY derivatives has been achieved using two common Brønsted acids; treatment with trifluoroacetic acid (TFA) or methanolic hydrogen chloride (HCl) followed by work-up with Ambersep® 900 resin (hydroxide form) effects this conversion in near-quantitative yields. Compared to existing methods, these conditions are relatively mild and operationally simple, requiring only reaction at room temperature for six hours (TFA) or overnight (HCl).

Metal Ions Removal

The calcium peroxide microparticles were synthesized and evaluated as an innovative oxidant to remove Fe (III) and Cr (III) from waste liquid of COD determining samples. The CaO2 microparticles were 0.1-0.3 μm in diameter and the average CaO2 content was 80%. Experiments were performed to investigate the influence of contact time, pH of solution and CaO2 microparticles dosage on the efficiency of Fe (III) and Cr (III) removal. Up to 100.0% and 99.8% removal efficiency for Fe (III) and Cr (III) respectively was obtained by microparticles dosage of 10000 mg/L at 30 min and pH 7.46. It could be concluded that the removal efficiency was enhanced by increasing CaO2 microparticles dosage and reaction time, but decreased by increasing pH. These results suggest that CaO2 microparticles may be used to develop a simple and efficient removal method for waste liquid of COD determining samples.
