Abstract:

ZrOCl2, NiCl2 and NaH2PO4 were used as raw materials to prepare nickel zirconium phosphate(NiZr(PO4)2·4H2O, NiZrPs) by a microwave-assisted method at lower temperature and atmospheric pressure. The influence of three different kinds of surfactants on the phase, particle size and morphology of NiZrPs was studied. The results show that the addition of surfactant can reduce the particle size. Compared with sodium dodecyl sulfate(SDS), polyvinylpyrrolidone K30(PVP-K30) and hexadecyltrimethyl ammonium bromide(CTAB) can restrain the growth of particles more efficiently, resulting in a smaller average particle size. Moreover, the visible-light photocatalytic property of NiZrPs was studied based on methylene blue(MB) as a simulated wastewater. As a result, the visible-light apparent dye decolorization efficiency of NiZrP prepared with PVP-K30 is 49.0% which is much higher than that of the other two products. This work developed a new method for the preparation and application of new type zirconium phosphate complex salt.
