| 摘 要： | 采用浸渍法制备Pd-W-Cu/γ-Al2O3催化剂,用XRD和SEM方法对该催化剂进行了表征.以氢气作为还原剂,在间歇式反应器中对催化还原地下水中硝酸盐进行了实验研究,考察了催化剂制备方法对催化还原硝酸盐性能的影响.结果表明,W的添加改善了Pd的分散性,提高了催化剂的活性和选择性.金属Pd/W/Cu质量比、浸渍顺序和焙烧温度对催化性能有较大影响.Pd/W/Cu质量比为3∶1∶1,Pd、Cu和W3种金属组分同时浸渍,焙烧温度为400℃时,催化剂的活性和选择性最高.在NO3--N初始浓度为100mg·mL-1条件下,催化反应60min后水中NO3--N和NO2--N浓度均为0mg·mL-1,NH4+-N浓度为2.5mg·mL-1.
