Factors affecting of zinc biosorption by padinaboergeseni

Mohammad Jaberi,Mahmood Niad,

The Several isotherms and kinetics models for zinc biosorption by the padinaboergeseni as brown algae were investigated. The effects of operating parameters such as initial pH, temperature, ionic strength, initial zinc concentration, biomass concentration and contact time on the Zn biosorption were analysed. Design of the experiments was done in the response surface methodology by using Box–Behnken model in the Minitab software for cooperating parameters such as initial pH, temperature, ionic strength and contact time. A mathematical function for zinc uptake by padina boergeseni was developed.
