Multi-chamber electroosmosis using textile reinforced agar membranes – A promising concept for the future of hemodialysis

摘要: Renal replacement therapy options are limited to hemodialysis and peritoneal dialysis (70% of US patients) or renal transplantation. Diffusion processes the main physico-chemical principle behind hemodialysis. An alternative way achieve liquid flow through membranes bases on electroosmotic which is observed as electrokinetic phenomenon in porous bear surface charges. Agar consists non-ionic agarose negatively charged agaropectine thus an flux analytical electrophoresis. In this study potential electroosmosis textile reinforced agar separation method was investigated. Using a five-chamber electrolysis cell membrane/cellulose fabric composite intensive 1-2 ml cm(2) h(-1) at 100 mA current could be observed. The movement cations structure led flux, also transported uncharged molecules such urea, glucose membrane. Separation low molecular weight determined by membrane characteristic. transport ions (K(+), PO4(3-), creatinine) (urea, glucose) experiments monitored using pH 5.5 phosphate electrolyte with aim assess overall electrochemical cell. results demonstrate for filtration biological fluids absence external pressure high shear rates.
