Kinetics and equilibrium study for the biosorption of lanthanum by .

Lanthanum (La) is a light rare-earth element that plays an essential role in manufacturing technological products, clean technologies, medical products, electron cathodes, scintillators, fluorescent lamps, and fertilizers. This study is the first investigation of La biosorption using inactive lyophilized biomass from INCQS 40,211. The maximum sorption capacity (q) for was 7.81 mg g. La biosorption followed the Freundlich model, where the biosorption system possibly multilayer coverage of by lanthanum ions. The kinetic data for the adsorption process obeyed a pseudo-second-order (  > 0.92), indicating chemical sorption. The results indicated that inactive lyophilized biomass from INCQS 40211are an excellent candidate for removing light rare-earth elements from aquatic environments.
