为更好的处理水环境中的锑（Ⅲ）污染问题，采用超声共沉淀法制备了铁锰层状双氢氧化物（Fe-Mn LDH），并研究初始pH、投加量、共存离子、吸附时间及温度等因素对Fe-Mn LDH去除废水中Sb（Ⅲ）的影响。通过扫描电子显微镜（SEM）、能谱仪（EDS）、X射线衍射（XRD）、X射线光电子能谱（XPS）和傅里叶红外光谱（FTIR）等表征手段对材料晶体结构、形貌、吸附机制等进行了表征及分析。结果表明Fe-Mn LDH去除Sb（Ⅲ）的适宜条件为：pH=5、投加量为0.4 g/L、吸附时间150 min；在此条件下，在温度45℃时最大吸附量为77.39 mg/g。吸附过程符合拟二级动力学模型，Freundich吸附等温线模型能够很好的描述Fe...

In order to solve the problem of antimony(III) pollution in water environment, Fe-Mn layered double hydroxides (Fe-Mn LDH) were prepared by ultrasonic co-precipitation method, and the effects of initial pH, dosage, coexisting ions, adsorption time and temperature on the removal of antimony(III) from wastewater by Fe-Mn LDH were studied. The crystal structure, morphology and adsorption mechanism were characterized and analyzed by SEM, EDS, XRD, XPS and FTIR. The results show that the suitable conditions for antimony(III) removal are pH of 5, dos...
