Making Calcium Alginate Chitosan Membrane And Permeability Testing
Introduction
The dialysis membrane is a crucial component in the hemodialysis process, which helps cleanse the patient's blood with kidney failure. The latest research focuses on developing dialysis membranes with better performance, one of which is by utilizing a combination of natural biopolymers such as alginate and chitosan. This article discusses the process of making calcium alginate-chitosan membrane and its potential as a dialysis membrane.
The Process of Making Calcium Alginate-Chitosan Membrane
The calcium alginate-chitosan membrane is made through a simple but effective process. Alginate, a polyanionic biopolymer, is mixed with chitosan, a polycationic biopolymer. The reaction between the two biopolymers produces polyelectrolytes of alginate. Furthermore, this polyelectrolyte is reacted with a calcium chloride solution, which forms a helat and produces a calcium alginate membrane.
The Reaction Between Alginate and Chitosan
The reaction between alginate and chitosan is a crucial step in the production of the calcium alginate-chitosan membrane. The polyanionic nature of alginate and the polycationic nature of chitosan create a strong electrostatic interaction, resulting in the formation of a polyelectrolyte complex. This complex is then reacted with a calcium chloride solution, which forms a helat and produces a calcium alginate membrane.
Characteristics of Calcium Alginate-Chitosan Membrane
Research shows that the calcium alginate-chitosan membrane has a promising characteristic for dialysis applications.
Tensile Strength
The tensile strength of the calcium alginate-chitosan membrane is a critical parameter in its application as a dialysis membrane. The membrane has a fairly good tensile strength, with a load value and stroke of 0.16 and 2.81, respectively. This shows that the membrane has adequate structural strength to withstand pressure and strain during the dialysis process.
Surface Morphology
The surface morphology of the calcium alginate-chitosan membrane is unique, with a porous structure that can increase permeability and fluid flow. Study with an electron scanning microscope (SEM) shows that the membrane has a porous structure with a high surface area, which can facilitate the exchange of molecules between the blood and the dialysate.
Permeability
The permeability of the calcium alginate-chitosan membrane is a critical parameter in its application as a dialysis membrane. The membrane permeability of various molecules, such as urea, sodium salicylate, and albumin, was tested to assess their abilities in the blood filtration process. The results showed that the calcium membrane of the alginate-chitosan was able to filter various molecules with good efficiency.
Potential of Calcium Membrane Alginate-Chitosan as a Dialysis Membrane
The results showed that the calcium membrane of the alginate-chitosan had great potential as a dialysis membrane. The combination of properties possessed, such as good tensile strength, porous structure, and optimal permeability, make this membrane a promising alternative to improve the efficiency and safety of the dialysis process.
Advantages of Calcium Membranes Alginate-Chitosan
The calcium membrane of the alginate-chitosan has several advantages compared to conventional dialysis membranes:
