用于焦化废水脱除苯酚的亲水性多孔炭纳米球基表面分子印迹聚合物的制备
A hydrophilic surface molecularly imprinted polymer on a spherical porous carbon support for selective phenol removal from coking wastewater
摘要
Abstract
A novel hydrophilic surface molecularly imprinted polymer from bi-functional monomers on a porous carbon nanosphere support (AMPS-Am/MIP) was prepared to improve the selective adsorption capacity towards phenol from coking wastewater using hydrophilic 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and acrylamide (Am) as the monomers,and phenol as the imprinting molecule.The surface morphology,functional groups,thermal stability and hydrophilicity of AMPS-Am/MIP were investigated,and the adsorption properties including kinetics,isotherms,selectivity and regeneration were tested.Results showed that the adsorption of AMPS-Am/MIP towards phenol in water reaches equilibrium in 180 min and the highest adsorption capacity was 96.59 mg g-1.Its selection factor for phenol is as high as 1.67 in the presence of structural analogs,quinoline and hydroquinone.The adsorption capacity remained above 80％ of the initial adsorption value after five adsorption-regeneration cycles.When the pH value of the phenol-containing water was around 8,close to that of coking wastewater,the adsorption capacity reached 46.84 mg g-1,indicating the applicability and high efficiency of AMPS-Am/MIP for phenol adsorption in alkaline coking wastewater.关键词
