Abstract: The invention comprises a method of isolating at least some of the high molecular weight organic compounds containing basic groups such as proteins, polypeptides, bacteria, virus and enzymes, from solutions containing them, by the steps of bringing the solution into contact with a lignocellulosic material which has been sulphonated to such an extent that its ion exchange capacity reaches to at least 0.15 milliequivalents per gram, and separating the solution from the sulphonated lignocellulosic material.
