| Popis: | A novel environmentally friendly biocomposite namely calcium alginate immobilized Ammi Visnaga ( Khella ) extraction waste was prepared by electrostatic extrusion method. A full factorial design 2 3 was used to optimize the beads preparation conditions. The effect of sodium alginate concentration ( X 1 ), biomass concentration ( X 2 ) and cross-linker concentration ( X 3 ) on the Cd 2+ removal efficiency was examined in a batch system with a fixed biocomposite dose of 1 g/L. Using the experimental results, a linear mathematical model representing the influence of different variables and their interactions was obtained. The optimized values of X 1 , X 2 and X 3 were found to be 4.35%, 2.5% and 1.99% respectively. The biocomposite beads were characterized by ATR spectroscopy, scanning electron microscopy for the surface morphology and optical microscopic for the particles size measurements. |
