The aim is to establish a long column with the lowest possible cost and the economic life of__delta_alpha_alpha gamma_by using new membrane materials. Income flow, one of which may occur in the event of an accident, even in some environmentally burdened compounds with__delta_alpha_alpha gamma_gamma_kappa_activity.The active ingredient provided in accordance with the present invention is Mr. _Zeta Delta_alpha_alpha gamma_gamma_kappa_active component of a polymer, such as a polymer or oligomer_Zeta Delta_alpha_gamma_kappa_. As an active component of high molecular weight, it is based on the size of membrane and membrane rejection (3) as__delta_alpha_alpha gamma_gamma_kappa_.
