"CuO-γ-Al2O3催化剂在处理高浓度难降解有机废水,尤其是苯胺模拟废水方面表现出显著效果。通过浸渍法制备的这种催化剂,经过SEM(扫描电子显微镜)和XRD(X射线衍射)分析,用于H2O2催化氧化体系,以提升废水的降解效率。研究关注了Cu含量、浸渍时间、焙烧时间和焙烧温度等因素对苯胺去除率的影响。结果显示,最优条件为Cu含量5%,浸渍24小时,500℃焙烧5小时,此时苯胺去除率可达到87.28%。该研究强调了CuO-γ-Al2O3催化剂在湿式氧化过程中的应用潜力,尤其在环保和经济性方面,为处理化工工业产生的苯胺废水提供了一种有效途径。" 在环境工程领域,处理高浓度、难降解有机废水是一项挑战。苯胺,作为一种有毒的苯衍生物,因其对人体健康和环境的危害,成为关注焦点。湿式氧化技术(WAO)自1958年以来被广泛研究,而催化湿式氧化(CWAO)则进一步提高了处理效率,减少了二次污染。本研究中选用的CuO-γ-Al2O3催化剂,因其原料丰富且成本相对较低,成为了非均相催化剂的理想选择。 实验部分详细介绍了催化剂的制备过程,采用等体积浸渍法,通过改变Cu含量、浸渍时间和焙烧条件,探索了最佳的催化性能。XRD分析可以确定催化剂的晶体结构,而SEM则能揭示催化剂表面的微观形貌,这两者对于理解催化剂的活性和稳定性至关重要。通过这些表征手段,可以优化催化剂的制备工艺,以提高其在苯胺降解中的效能。 在所研究的条件下,5%的Cu含量、24小时的浸渍、500℃的焙烧温度以及5小时的焙烧时间组合下,苯胺的去除效果最佳,达到87.28%,这表明该催化剂在常温常压下的催化氧化反应中具有良好的性能。这为实际应用提供了重要的参考,特别是在处理含苯胺的化工废水时,可以降低对复杂设备的需求,减少运行成本。 总结而言,该研究揭示了CuO-γ-Al2O3催化剂在处理高浓度苯胺废水中的高效性和实用性,为湿式氧化技术在环境保护和工业废水处理领域的应用开辟了新的可能性。未来的工作可能包括进一步优化催化剂配方,探究其长期稳定性和扩展到其他难降解有机物的处理。
