Abstract Adsorption of d, l -Phenylalanine onto polymeric adsorbents (Amberlite XAD-4 and XAD-16; Sephabeads SP206 and SP207) was studied. Adsorption equilibrium isotherms were measured by batch equilibration at 15 and 40°C, showing the possibility of using a parametric pumping technique for aminoacid purification/recovery. Dynamic studies in a laboratory adsorption column Amicon Column (22 × 500 mm) were carried out to further screen adsorbents and obtain mass transfer parameters to be used in… 
Adsorptive purification of phenol wastewaters: Experimental basis and operation of a parametric pumping unit
