EFFECTS OF POROSITY AND SURFACE PROPERTIES OF POLYMERIC RESINS ON ADSORPTION CAPACITY OF PHENOL
In this work the effects of physical and surface properties of polymeric resins on adsorption capacity of phenol were investigated BET surface areas and pore size distributions of the polymeric adsorption resins,NKA Ⅱ(polar resin),AB 8(weak polar resin) ,D4006(weak polar resin) and D16(non polar resin),were separately measured by ASAP 2010M,and isotherms of phenol on the resins were separately estimated by the method of static adsorption Results indicated that the adsorption capacity of NKA Ⅱ resin for phenol in dilute aqueous solution was the highest,and the adsorption capacity of AB 8 resin was in the next place;and the micropore volume and polarity of a polymeric resin showed a strong influence on the adsorption capacity of phenol on the resin Among the four sorts of resin, the adsorption capacity of the NKA Ⅱ resin for phenol was the highest since it is not only polar but also possesses a considerable portion of micropore volume
