| Popis: | A method has been designed for making spherical microencapsulation of activated-carbon particles for use in the removal of metabolic wastes and/or toxins from blood. This bench-scale method was able to make better uniformity in particle size, and at a higher particle production rate. The material properties such as particle size, particle porosity, electromicroscopy of surface morphology, surface hardness, and pore-size distribution were characterized in order to conclude with their adsorption capacity for specific toxin solutes. The performance characteristics of these self-prepared particle encapsulation was also evaluated against the commercially available hemoperfusion particles, e.g., Kuraray's DHP (Japan). The encapsulation particles were also coated with polyhydroxyethyl methacrylate (PHEMA) for blood compatibility purpose. |
