Synthesis of Fe3O4 magnetic nanoparticles modifieded with sodium dodecyl sulfate and its performance on the removal of reactive dye Lanasol Blue (3R) from aqueous solutions

In this paper Fe2O3 nano-particles as sorbent was used to remove lanasol blue (3R) dye from aqueous solution in order to investigate its adsoption properties. Fe3O4 nono-particles were synthesisd by precipitation method and size is determined by Scaning Electron Microscope (SEM)[1]. The adsorption and removal of lanasol blue dye from Aqueous solution was studied in conditions lodoratory[2]. In this research various physic-chemical parameters were studied such as solution pH initial dye concentration amount of surfactant temperature contact time and salt (CuSO4 , Cd(NO3)2 , Pb(NO3)2 , CaCO3 , Mg(NO3)2 , NiCl2 and K2Cr2O7). The results showed an excellent adsorption capability for lanasol Blue (3R) dye in higher pH less contact time and room temperature. The results indicates that magnetit nono-particles have advantages such as high removal efficieny and short reaction time and cab be effectively used to remove color particle from wastewater containing dye.In this study, according to the results of an examination of the effective parameters in the adsorption process such as pH, contact time, the initial concentration of color and the effect of intruder ions on optimal conditions that for example in pH=3 and room temperature, optimum and maximum result were the absorption process.
