Adsorption of the Selenium Ion to Copper Nitrate Hydroxide

Since the growing interest in the manufacture and environmental applications of nanocomposites consisting of CuO and TiO2nanoparticles (NPs), related toxicological effect and interaction with cellular structures for these newly developed materials are still unknown. Recent literature reveals that nanosized CuO and TiO2particles have cytotoxicity risks and ability to cause oxidative stress on health. This work considers the CuO doped TiO2nanocomposite particles were synthesized via a coprecipitation method with aqueous solutions as precursors of copper nitrateand titanium dioxide. Moreover, the nanocomposite particles were characterized using TGA-DTA, UV-Vis and TEM measurements. The calcination temperature was selected at 873 K. The nanocomposite particles were characterized by TEM, as the primary particles, aggregates ranged from 30 to 100 nm and have a good dispersion character. Cell cytotoxicity assessment and the percentage cell survival was determined by using 3-(4,5-dimethylthiazol-2-yl)-5(3-carboxymethoxyphenol)-2-(4-sulfophenyl)-2H-tetrazoli um (MTS) assay on human fetal lung tissue cell (MRC-5). The experimental results show that the CuO doped TiO2nanocomposite particles cause potential cytotoxicity effect in cultured human cells.

Blue Photoluminescence

A novel phosphor, copper doped hydronium alunite ((H3O)Al3(SO4)2(OH)6:Cu), exhibiting a blue photoluminescence peak at a wavelength of 420 nm was successfully synthesized from aluminum and copper sulfates solution under hydrothermal condition (240 °C, 60 min). The measurement of XRD revealed that the obtained products were single phase with a crystal structure of (H3O)Al3(SO4)2(OH)6. Luminescence intensity of (H3O)Al3(SO4)2(OH)6:Cu synthesized from sulfates solution was 6.2 times higher than that from an aluminum nitrate solution mixed with an elemental sulfur and a copper nitrate solution. The increase of luminescence intensity was resulted from an improvement of the crystallinity of (H3O)Al3(SO4)2(OH)6.

The activated carbon loaded copper oxide catalyst was prepared from Hainan abandoned coconut shells using chemical activation method and applied in treatment of acid bright red GR simulation dyeing wastewater. The effects of phosphoric acid concentration, ratio of liquid to solid, activation time and activation temperature on the COD and color removal rates were investigated by orthogonal experiment. The results showed that the optimal values of the parameters above were 65% (in mass), 3:1, 2.5h and 500°C under the designed copper oxide loading conditions of calcining temperature 300°C,calcining time 3.0 h and use level of copper nitrate 15 mL. Using the prepared sample for the treatment of the wastewater, the COD and color removal rates reached 94.384% and 99.840%, respectively.

Super-hydrophobic film with hierarchical micro/nano structures was prepared by galvanic replacement reaction process on the surface of galvanized steel. The effects of the etching time and copper nitrate concentration on the wetting property of the as-prepared surfaces were studied. Scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and electrochemical technique were employed to characterize the surface morphology, chemical composition, and corrosion resistance. The stability and self-cleaning property of the as-fabricated super-hydrophobic film were also evaluated. The super-hydrophobic film can be obtained within 3 min and possesses a water contact angle of 164.3° ± 2°. Potentiodynamic polarization measurements indicated that the super-hydrophobic film greatly improved the corrosion resistance of the galvanized steel in 3.5 wt % NaCl aqueous solution. The highest inhibition efficiency was estimated to be 96.6%. The obtained super-hydrophobic film showed good stability and self-cleaning property.

A hyrdrothermal reaction process has been developed to prepare rod-like crystals of copper oxide using copper nitrate trihydrate as a function of synthesis temperature, stirring speed and solution pH value. The properties of the fabricated crystals were studied using scanning electron microscopy, X-ray diffraction and particle size analysis. The morphology of the synthesized CuO was dependent on both the pH value of the solution and the morphology of the seed materials. Synthesized particles have regular morphologies and a uniform size distribution.
