摘要
采用溶胶-凝胶法制备了CeO2-ZrO2介孔材料,研究了该介孔材料对水中Cr6＋的吸附性能,并通过小角XRD、大角XRD、TEM、N2吸附对介孔材料的表征分析了不同吸附条件对吸附性能的影响,结果表明,在室温下,较广的酸性范围内（pH=2-7）,吸附剂都能表现几乎相同的效果,吸附时间20min吸附几乎达到平衡,吸附量可达9.63mg·g^-1,去除率可达96.3%。
Mesoporous CeOz-ZrO2 was prepared via sol-gel approach and applied to adsorbing chromium （VI） in water. The mesopoeous CeO2-ZrO2 materials were characterized by small-angle XRD,wide-angle XRD,TEM,N2-adsorption,and the adsorption efficiency of chromium（VI） with Mesoporous CeO2-ZrO2 as adsorbent under different adsorption conditions was investigated. The results indicate that adsorptive capacity and removal rate of chromium （VI） are up to 9.63 mg.g^-1 and 96.3% in room temperature, respectively. The adsorptive effects for chromium （VI） just perform similarly in a wide range of pH（pH=2-7） , and 20 rain of adsorptive time reaches equilibrium almost.
