| 摘 要： | 以铁泥为原料,经酸浸、过滤、加入硫酸铵、调节pH等工序制得黄铵铁矾((NH4)Fe3(SO4)2(OH)6).采用X线衍射、扫描电子显微镜、N2吸附-脱附等手段对其进行表征.在H2O2/(NH4)Fe3(SO4)2(OH)6类Fenton条件下,对亚甲基蓝(MB)溶液进行处理.考察各种因素对溶液中MB的去除的影响.研究结果表明:在酸性媒介中黄铵铁矾能有效去除水溶液中的MB,去除率随H2O2浓度的增加而增加.100 mL H2O2浓度为11.4 mmol/L,pH为5.6,MB质量浓度为100 mg/L,(NH4)Fe3(SO4)2(OH)6质量浓度为0.9 g/L的水溶液,在80℃时反应20 min后MB的去除率达到99％以上,催化剂循环使用重复性良好.
