Abstract

The adsorption of pyidine and N

N-dimethylaniline by a phenolic resin adsorbent JDW-2 in nonaqueous systems was investigated under static conditions．Experimentol results indicated that the dominating mechanism of adsorption of pyridine and N

N-dimethylaniline by the adsorbent in hexane is a hydrogen bonding sorption process．The equilibrium sorption date for adsorbent JDW-2/pyfidine(or JDW-2/N

N-dimethylaniline) systems in hexane showed good agreement with the Imngmuir isotherm equation The correlation coefficients are larger than 0.99．It implies that the sorption of pyfidine and N

N-dimethylaniline onto the adsorbent in hexane systems is a monomolecular sorption．The influence of ethanol and ethyl acetate concentrations in hexane solutions on the adsorption of pyidine and N

N-dimethylaniline was also studied．
