Özet
Synechocystis aquatilis was immobilized in Ca-alginate via entrapment. The plain alginate, and alive and heat-inactivated immobilized algae beads were used for the sorption of Cu2+ ions from aqueous solutions at 25 degrees C. Kinetic studies showed a fast initial rate, followed by a slower biosorption one. Adsorption of Cu2+ on the biosorbents increased with increasing initial Cu2+ ions level in the solution. The heat-inactivated alga preparation showed a higher biosorption capacity than the alive counterpart.
