摘要
Abstract
Among the six kinds of macroporous adsorption resin,the RD-100 was screen out with the best adsorption capacity to remove o-nitrochlorobenzene(OCNB)and o-nitrophenol(ONP)from the wastewater of 1-hydroxybenzotriazole producing.The static adsorption kinetics study showed that the adsorption kinetics of the resin RD-100 for OCNB and ONP conformed to the pseudo-first-order model,and the adsorption process conformed to the Freundlich model,that is a multi-molecular layer adsorption.The maximum theoretical adsorption capacities of the resin for OCNB and ONP were 1 087.0 mg·g-1 and 574.7 mg·g-1,respectively.The thermodynamic study indicated that the adsorption of OCNB by the resin RD-100 was an endothermic process while the adsorption of ONP was an exothermic proces and,their adsorption enthalpies were 88.5 kJ·mol-1 and-2.1 kJ·mol-1,respectively.After six cycles of static adsorption and regeneration,the adsorption capacity only decreased by 5.5%(OCNB)and 6.2%(ONP).For single-component dynamic adsorption,the breakthrough points(Ct/C0=5%)were 420 min for ONP and 580 min for OCNB.The results suggest that the resin RD-100 can effectively adsorb OCNP and ONP from wastewater.关键词
