Biosorption optimization, characterization, immobilization and application of Gelidium amansii biomass for complete Pb²⁺ removal from aqueous solutions.

ABSTRACT: Lead (Pb²⁺) is among the most toxic heavy metals even in low concentration and cause toxicity to human's health and other forms of life. It is released into the environment through different industrial activities. The biosorption of Pb²⁺ from aqueous solutions by biomass of commonly available, marine alga Gelidium amansii was studied. The effects of different variables on Pb²⁺ removal were estimated by a two-level Plackett-Burman factorial design to determine the most significant variables affecting Pb²⁺ removal % from aqueous solutions. Initial pH, Pb²⁺ concentration and temperature were the most significant factors affecting Pb²⁺ removal chosen for further optimization using rotatable central composite design. The maximum
