为提高纳米零价铁（nZVI）在类芬顿体系中的催化效能，将液相还原法生成的纳米零价铁负载在经十六烷基三甲基溴化铵（CTAB）改性后的伊利石上，制备成类芬顿催化剂（It/CTAB@nZVI）；采用XRD、SEM 及FTIR等方法对催化剂（It/CTAB@nZVI）的形貌和结构进行了表征，并以头孢哌酮（CPZ）为目标污染物，分别考察了H2O2浓度、催化剂投加量及pH对CPZ去除效果的影响，初步探究了It/CTAB@nZVI类芬顿体系降解废水中头孢哌酮的机理。结果表明，nZVI已成功地附着在改性后的伊利石表面，能有效防止纳米零价铁的团聚，提高了其在类芬顿体系中的催化效能；在H2O2浓度为3.2 mmol·L-1、It/CTAB@nZVI投加量为0.03...

In order to improve the catalytic performance of nano-zero-valent iron (nZVI) in Fenton-like system, the nano-zero-valent iron (nZVI) generated by liquid phase reduction method was supported on illite modified by cetyltrimethyl ammonium bromide (CTAB), and a Fenton-like catalyst of It/[email protected] was prepared. The morphology and structure of It/[email protected] were characterized by XRD, SEM and FTIR. Cefoperazone (CPZ) was taken as the target pollutant, and the effects of H2O2 concentration, catalyst dosage and pH on CPZ removal were in...
