Study on Preparation of Zn/Al Double Metal Oxide by Ion Exchange Method

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.
