Dialysis transport mechanism

WebDonnan dialysis is a continuously operating ion-exchange process. There are many theoretical models describing transport mechanisms and kinetics of DD [18–26]. All transport kinetics models are based on Fick's or Nernst-Planck's equations for ion fluxes. In both cases, the authors introduce many assumptions and simplifications. Polyelectrolytes WebHemodialysis removes blood and passes it through an extracorporeal circuit and an artificial membrane, with dialysate running in countercurrent flow next to the blood in the membrane. After the blood is filtered through the membrane, it is returned to the body with a reduced quantity of metabolic waste products.
