Modification of Natural Zeolites and their Ammonia Adsorption Characteristics

  • 摘要: 为研究不同改性方法及其组合顺序对天然沸石吸附NH4+效率的影响及其吸附特征,选择盐、高温、酸3种改性方法进行不同组合. 结果显示,改性组合顺序对天然沸石的吸附性能影响较明显,最佳改性组合顺序为“盐+酸+高温”,其改性后的沸石在初始ρ(NH4+)为15、30和50 mg/L下对NH4+的去除率分别为87%、92%和94%. 采用Langmuir和Freundlich 2种方程来拟合“盐+酸+高温”改性后沸石的吸附行为,表明其更符合Langmuir模型,R2为0.998 5,其最大吸附量(qmax)为8.23 mg/g,并且其吸附过程符合一级动力学方程, R 2为0.998 1. 扫描电子显微镜(SEM)和比表面积(BET)分析结果表明,沸石经最优组合改性后表面形态明显变化,比表面积增大.
