摘要： The invention relates to new sorbents of cellulose basis capable of forming inclusion complexes, as well as to a process for the preparation thereof. The new sorbents according to the invention are cellulose derivatives containing structural units of the general formula (I), ##STR1## wherein Cell is a group derived by removing m hydroxy groups from the glucose unit of the cellulose chain,m is an integer of 1 to 3,CD is a group derived by removing one hydroxy group from the .alpha., .beta. or .gamma.-cyclodextrin molecule,n is an integer of 1 to 5, andp stands for 0 or 1, which may optionally vary even within a single chain.The cellulose derivatives according to the invention are substances of loose structure, with large specific surface area and good swelling properties, which can be applied for solving the most diverse adsorption tasks. Thus e.g. the substances can be applied for the preparation of smoke filters in cigarettes, waste water purification (de-poisoning) filters, inserts for removing solvent vapors, etc., furthermore for solving specific tasks of fractionation according to molecular dimensions.
