Ultrafiltration membranes made of secondary cellulose acetate modified with active carbon

It was hypothesized that active carbon will play the role of an inert filler and cause the formation of a more developed pore structure in membranes since pores are formed as a result of the counteraction of the forces of contraction and adhesion during phase separation in evaporation of the solvent. The carbon particles perturb the structure of the polymer network The porosity of the membranes also increases because the filler has a porous structure. Active carbon can be used to improve the performance properties of membranes.
