摘要
采用表面覆载法制得铁氧化物/沸石(IOCZ)吸附剂,用X射线衍射、扫描电镜、红外光谱等方法对IOCZ进行了表征.研究了IOCZ对亚甲基蓝(MB)和Cu2+的吸附行为,考察了吸附剂用量、溶液pH值、盐浓度、温度等因素对IOCZ吸附的影响.通过Langmuir吸附等温式对实验数据进行线性回归分析,表明IOCZ对MB和Cu2+的吸附均符合Langmiur吸附等温式,吸附过程均为吸热反应.IOCZ对单一体系中MB,Cu2+的吸附能力分别大于对混合体系中MB,Cu2+的吸附能力;在混合体系中,MB的存在显著抑制了IOCZ对Cu2+的吸附.
The research is designed to test the properties of an adsorbent,iron-oxide-coated-zeolite (IOCZ),which is prepared by coating iron oxide onto the surface of zeolite,for adsorption of methylene blue (MB) and Cu2+ ions from synthetic solutions. XRD,SEM and infrared spectra analysis are used to examine and compare the characteristics of natural zeolite and IOCZ. The effects of various experimental conditions,such as adsorbents dose,pH values,coexisting common metal ions and temperatures are studied in batch ad...
