Ascitic Fluid Ultrafiltration through Polysulfone-Polyaniline
Composite Membranes

Abstract:

The paper presents the ascitic fluid ultrafiltration using asymmetric and composite membranes. For this reason, two variants of polysulfone - polyaniline composite membranes were used. Permeate flow was within the values known for this type of membranes. The retention of components is favourable, being characteristic for ultrafiltration using membranes with low hydrophilicity. The process was conducted at pH 6.5 (natural value of ascitic fluid). The ascites fluid used was preserved only through freezing and not chemically. In addition to albumin, bilirubin and uric acid were concentrated. Globulins are retained on the surface and inside the membranes. Ultrafiltration of ascites fluid through 12% polysulfone-polyaniline composite membranes in both coagulation variants provided good results that offer real outlooks for albumin recovery. Keywords: albumin recovery, ascitic fluid, composite membranes, ultrafiltration
