Popis: | 93 Some chitosan beads were prepared by ionic cross-linking with sodium tripolyphosphate and chemical cross-linking with glutaraldehyde in this research to increase the mechanical strength and stability in acidic solution. Investigation the adsorption capability of heavy metal, Pd2+ with chitosan bead in solution was studies in this research. The PCS and SEM were used to determine the particle size and appearance of beads. Microemulsion technique was used to prepare smaller chitosan bead with higher degree of cross-linking. Sodium tripolyphosphate-chitosan bead prepared from micro-emulsification have saturation adsorption amount 80.65 Pb2+ mg/g chitosan with a average particle size of 500nm. |
