摘要
铁氧化物对有机胂酸的吸附性能差异较大,对有机胂酸的吸附量在0.002~173 mg/g左右,吸附速率在0.00007~30.06 g/(mg·h)的范围之内。首先分析了有机胂酸的类型、铁氧化物表面性质、pH、和温度对铁氧化物吸附有机胂酸的影响;其次阐述了腐殖酸对有机胂酸在铁氧化物上的吸附受腐殖酸浓度和pH的影响;介绍了腐殖酸对有机胂酸吸附过程的影响机制包括分子间作用、静电作用和络合作用机制;最后,对铁氧化物和有机胂酸的研究及应用进行了展望。
The adsorption properties of iron oxides to organic arsenic acid vary greatly,and the adsorption amount of organic arsenic acid is about 0.002~173 mg/g,and the adsorption rate is within the range of 0.00007~30.06 g/(mg·h).Firstly,the effects of the type for organic arsenic acid,the surface properties,pH,and temperature of the iron oxide on the adsorption of organic arsenic acid by iron oxide were analyzed.Secondly,the adsorption of humic acid on organic arsenic acid on iron oxides was affected by humic acid concentration and pH.The influence mechanisms of humic acid on the adsorption process of organic arsenic acid,including intermolecular action,electrostatic action and complexation mechanism,were introduced.Finally,the research and application of iron oxides and organic arsenic acids are prospected.
