註釋In this work the main objective was to extract sodium and potassium ions economically and efficiently from the used dialysis solution, thereby leading to a more effective peritoneal dialysis system. Currently patients with end stage renal failure undergoing peritoneal dialysis have to replace the bag of the used dialysis solution after it has been emptied from the peritoneal cavity. This may be done many times a day. Further, the patients have to either remain immobile (stay at home or hospital) or find a hygienic way of disposing off the used dialysis solution. They have to carry extra set of bags with them which may be approximately 2.0-3.0 lit of solution and an empty bag, which is quite cumbersome, possibly unhygienic, embarrassing and invasive. The results of this work will lead to two embodiments that either use one or two bags in which the dialysis solution may be cleaned and recirculated. This would allow for a reduced number of bag removals as well as a more effective and efficient cleansing method. This work investigates the use of sol gel materials for the removal of the toxic ions, and concentrates on sodium and potassium ions to show the feasibility of the approach as well as developing the protocol for future research into extending the work to all other toxic ions that needs to be removed. The most significant contribution of this work is the development of a particular sol gel formulation that absorbs water as well as selectively absorbs potassium over sodium.
