摘　　要：Ni^(2+)与Al^(3+)物质的量比为3∶1,尿素为沉淀剂,通过水热合成技术制备镍铝层状双金属氢氧化物层状材料(Ni^(2+)-Al^(3+)-CO_3^(2-)-LDHs)。以Ni^(2+)-Al^(3+)-CO_3^(2-)-LDHs为前驱体,分别与Na Cl和十二烷基磺酸钠[CH_3(CH_2)_(11)SO_3Na]进行离子交换反应得到Ni^(2+)-Al^(3+)-CH_3(CH_2)_(11)SO_3^--LDHs新型吸附剂材料。将CH_3(CH_2)_(11)SO_3^-亲油客体负载到Ni^(2+)-Al^(3+)-LDHs层状材料层间,实现镍铝层状双金属氢氧化物的亲油改性。利用Ni^(2+)-Al^(3+)-CH_3(CH_2)_(11)SO_3^--LDHs复合材料对含油污水进行处理,结果表明,镍铝层状双金属氢氧化物亲油改性后增强了LDHs的亲油吸附性能。Ni2＋ -Al3＋ -CO32- -LDHs was prepared by homogeneous precipitation method with urea as precipitant, Ni2＋ andAl3＋molar ratio of 3 ： 1. Ni2＋ - Al3 ＋ - CH3 （ CH2 ） 11SO3- - LDHs was successfullysynthesized through ion exchange of Ni2＋ - Al3 ＋ - CH3 （ CH2 ） n SO3- - LDHs with NaCl and dodecyl sul-fonic acid[ CH11 （ CH2 ） 11SO3- ] respectively to load lipophilic CH3 （ CH2 ） 11 SO3- into interlayer space ofNi2＋ -Al3＋ -CO32- -LDHs. Ni2＋ -Al3＋ -CH3 （CH2 ）11 SO3- -LDHs was used as an adsorbent fortreatment of oil containing wastewater. The experiment results indicated that modification of Ni2＋ - Al3 ＋ -CO32- -LDHs with dodecyl sulfonic acid [ CH3 （CH2 ）11SO3-] ion enhanced oil adsorption properties.
