Abstract

In this work, the adsorption properties of both raw and pre-treated brown algae, Cystoseira indica, collected from Chabahar, Iran, for removal of cadmium (II) and Nickel (II) ions from aqueous solutions were studied in a batch system. The influence of pH and some chemical modifications were investigated. The effect of chemical modification with calcium chloride, hydrochloric acid, formaldehyde, glutaraldehyde and polyethylene imine was studied and it was found that the Cystoseira indica pre-treated by formaldehyde had the maximum removal capacity of 19.42 mg/g and 10.06 mg/g at an optimum pH of 5.5 and 6.0 for Cd and Ni, respectively (0.5 mmol/L Cd2+ and Ni2+, 2g/L biomass and 2hr of contact). To describe the biosorption ISOTHERMs, the twoparameter models: Langmuir, Freundlich, Temkin, Dubinin-Radushkevich and Flory- Huggins were applied. Results show that among biosorption ISOTHERMs, the Langmuir model describes the Cd (II) and Ni (II) biosorption quite well (for the two metals R2 were equal to 0.98) and the maximum monolayer biosorption capacity of FA-treated C. indica for Cd (II) and Ni (II) are 26.32 mg/g and 20.48 mg/g, respectively. The kinetic data of cadmium and nickel biosorption were fitted by a pseudo-second-order rate equation with a rate constant of 3.79x10-3 and 4.32xl0-3g mg-1 min-1, respectively and for the two metals R2 was equal to 0.99.
