Alginate is being applied in industry and engineering including the biomedical field because of its biocompatility, non-toxicity and biodegradability. The adsorption amounts of nickel, zinc and cadmium ion onto the alginate beads increased with increase in initial pH tem-perature due to increased dissociation rate of carboxyl group. The magnitude adsorption capacity of the heavy metal ions onto alginate beads was in the order of cadmium > zinc > nickel. The differences in the rate of adsorption of nickel, zinc and cadmium ions onto the alginate beads are primarily attributable to the differences in the equilibrium amount of the heavy metals. In addition, our results are found to fits the pore diffusion model.

Alginate, which exist in natural polymer, is a polysaccharide from brown seaweed. Alginate is being applied in industry and engineering, including the biomedical field because of its biocompatility, non-toxicity and biodegradability. Alginate has high affinity and selectivity for heavy metal ions. The particle size, surface area and average pore radius of the alginate bead were 0.21 cm, 25 m2/g and 40.5Å respectively. The adsorption amounts of nikel, zinc and cadmium ions onto the alginate bead were increased with increasing initial pH and temperature due to increase of dissociation rate of carboxyl group. The magnitude of adsorption capacity of the heavy metal ions onto alginate bead was the order of cadmium> zinc> nikel.

Alginate is natural carbohydrate material used to remove heavy metal ions from aqueous solutions. In this research, spherical alginate beads for batch adsorption experiments were made by sol-gel methods and characterized by BET and SEM. The adsorption rate of nikel, zinc and cadmium ions on the alginate bead increased with corresponding dosage of alginate bead. The internal diffusion coefficients were determined by comparing the experimental concentration decay curves with those predicted from surface and pore diffusion models. The adsorption rate of the heavy metal ions on alginate bead was the order of cadmium > zinc > nikel.
