| 摘 要： | 研究了改性蒙脱石负载纳米铁材料(NZVI-CMT)在甲醇-水体系中对四溴双酚A(TBBPA)的去除作用,并确定了反应温度、TBBPA初始浓度以及材料投加量等因素对去除效果的影响.结果表明,在25℃条件下,0.02 g NZVI-CMT对初始浓度为10 mg·L-1TBBPA溶液的去除率可达97.5%,而且NZVI-CMT对TBBPA的去除率明显高于两种单一材料即纳米零价铁(NZVI)及有机蒙脱石(CMT)的去除率(18.3%、67.3%),同时也大于两者之和(85.6%).利用NZVI-CMT对TBBPA进行重复去除实验时,前3次的去除率均可达到90%以上.通过检测降解产物并分析材料对TBBPA去除过程的特性,发现NZVI-CMT对TBBPA的去除以吸附为主,并伴有少量还原脱溴反应发生,而且较高的反应温度对降解反应有利. |
