Study on the adsorption property of p-nitrophenol on several adsorption resins

Tang Shu-min

Abstract

The behavior of static adsorption of AM-1,NDA-88,NDA-99,NDA-150 resins for adsorbing p-nitrophenol were studied.The results of static equilibrium adsorption showed NDA-88,NDA-99 and NDA-150 have higher adsorption capacities.The results of dynamic adsorption and desorption indicated that the adsorption capacity of NDA-99 towards p-nitrophenol is 3.75 mmol/g.Nearly 93% desorption efficiency for the desorption agent of 2 mol/L NaOH∶C_2H_5OH(1∶1) when the volume is 2.5 times as volume of resin could be achieved.
