ABSTRACT:
Process for the isolation of component materials of aqueous solutions by adsorption of the aqueous solutions on concentration agents based on silica gel and/or kieselguhr and subsequent extraction of the component materials with lipophilic solvents, which employs as concentration agents flowable silica gels and/or kieselguhrs with an average particle size of 0.05 to 1.0 mm., an average pore volume of 0.2 to 3 ml./g., and a specific surface of 0.2 to 50 m.sup.2 /g.
