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. The biosorption equilibrium was established approx. in 3 h, and the equilibrium was well-described by the Langmuir and Freundlich adsorption isotherms. The effect of pH was also investigated and the maximum adsorption of Cu2+ ions on the biosorbents was obtained approx. at pH 5.6.eninfo:eu-repo/semantics/closedAccesscopper(II) removalbiosorption of heavy metalsalgal biosorbentCa-alginateSynechocystis aquatilisArticle1542832882-s2.0-33645856493N/AWOS:000236769300007Q4
