Abstract:
Selecting reused polysulfone membrane (PSM) dialyzers as research objects, we mainly analyzed quantitatively the adhesion ingredients which obstructed the passage through the membrane, and we investigated the differences of residual contaminants on the surface of PSM in the cases of various reuse times. The results illustrated that after the completion of dialysis, the dialyzer was first cleaned by reverse osmosis (RO) water to remove the protein adsorpted. Then we used 2% sodium hypochlorite (NaClO) solution to soak it, and the glucose, cholesterol and triglyceride adsorpted were dissolved off. Meanwhile, the quantity of most of adsorption gradually increased with the increase of reuse times.
