Abstract: The optimum reaction conditions of D113 type ion exchange resin adsorption on Zn/Al ions and the microstructure of Zn/Al double metal oxide were researched with weight method and scanning electron microscopy. The results showed that when Zn/Al molar ratio was 2:1, the number of moles per unit mass of resin adsorption was biggest and the microstructure was better; with the increase of pH value and temperature, the number of moles per unit mass of resin adsorption increased. When the PH value was 3.89, the microstructure of calcined product was best, and the effect of temperature on the calcined product microstructure was little. EDS data and XRD spectra indicated that there were two kinds of ZnO and Al₂O₃ products.

Abstract: Nano-ZnO, nano-TiO₂ and their mixed catalyst respectively degrade methyl orange solution with concentration 10mg/L in sunlight. When the dosing quantity is 1g/L during 8h degradation, the degradation effect is better and the degradation rates of three catalysts can all reach more than 93% with prolonging of degradation time, and the degradation effect of mixed catalyst is best and its degradation rate reaches more than 99%. Moreover the effect of TiO₂ content in the mixed catalyst on catalytic degradation isn’t distinct.

Abstract: The 001×7 type cation exchange resins modified by zinc ion which acted as controlled release suppliers of ions composing crystal reacted with sodium hydroxide, saturated calcium hydroxide and ammonia solution respectively, and nano-ZnO dispersive liquid was preparaed. The result of ultraviolet analyse about the dispersive liquid showed that nano-ZnO dispersive liquid prepared by using saturated calcium hydroxide has higher nano-crystallization degree and better dispersity. The exploring results of temperature and reactive time showed that under 60°C and 16 hours conditions nano-ZnO dispersive liquid has better dispersity and can’t agglomeration and sedimentation.
