In the present study, adsorptive removal of rhodamin-B (RMN-B) from aqueous solution was investigated by using nano Zn–Al–Fe{sub 3}O{sub 4} incorporated sodium alginate (SA) beads. SA is a natural polysaccharide, non toxic and biodegradable material. The incorporation of Zn–Al–Fe{sub 3}O{sub 4} into SA was done by ionic polymerization method using CaCl{sub 2}. A batch mode study was used for the adsorption of RMN-B onto Zn–Al–Fe{sub 3}O{sub 4}/ alginate beads. The adsorption efficiency of RMN-B was investigated by the following modeling equations like Freundlich, Langmuir, Pseudo-first order, Pseudo-second order, Intraparticle diffusion, Gibbs free energy, Enthalpy and Entropy. The predicted experimental results of various modeling equations were implied that the process follow Langmuir and pseudo-second order equations. The intraparticle diffusion parameters indicate that the diffusion between RMN-B and nano beads were predominant in throughout of process. The surface morphology of nano beads of before and after adsorption were show that RMN-B is strongly adhered on whole surface of the nano material. The FTIR spectrum indicates that the RMN-B strongly adsorbed on the surface and TGA study reveals that the alginate/Zn–Al–Fe{sub 3}O{sub 4}/Ca material has an excellent temperature withstand capacity.
