摘要(Abstract)：

为了获得对三硝基甲苯(TNT)红水中有机物能有效富集的材料并研究其富集机理,通过对层间为碳酸根的MgFe层状双氢氧化物(MgFe-LDH)煅烧制备了镁铁氧化物复合物(MgFeO),而后在TNT红水中重构实现了对TNT红水中有机物的富集。并且MgFeO在以十二烷基苯磺酸钠(SDBS)、十二烷基磺酸钠(SDS)、对甲苯磺酸(PTS)、TNT水溶液为TNT红水模拟水中重构,研究其对有机物的富集机理。结果表明,TNT红水中有机物浓度越高,每克煅烧产物对TNT红水COD去除量越大,在研究范围内最高达到58 mg/g,且有机物疏水程度越高,越易于被富集,有机磺酸盐的长链结构有利于被富集,但此类物质强的表面活性会使重构产物表面形成FeOOH相。
