| Abstract: | The adsorption of pyidine and N,N dimethylanil ine by a phenolic resin adsorbent JDW 2 in nonaqueous systems was investigated under static conditions. Experimental results indicated that the dominating mechanism of adsorption of py ridine and N,N dimethylaniline by the adsorbent in hexane is a hydrog en bonding sorption process.The equilibriu m sorption date for adsorbent JDW 2/pyridine (or JDW 2/N,N dimethylan iline) systems in hexane showed good agreement with the Langmuir isotherm equation.T he correlation coefficients are larger than 0 99. It implies that the sorption of pyridine and N,N dimethylaniline onto the adsorbent in hexane systems is a monomolecular sorption.The influence of ethanol and ethyl acetate concentra tions in hexane solutions on the adsorption of pyidine and N,N dimethylanil ine was also studied. |
