Abstract :
In this work La0.7Sr0.3MnO3 , one group of nanosized perovskite-type oxides were prepared by sol-gel method. The perovskite structure has been characterized by X-ray diffraction (XRD) , scanning electron microscopy (SEM) , energy dispersive X-ray spectrometer (EDX) and Fourier transform infrared (FTIR) . The nanoparticles showed the excellent adsorption properties towards reactive blue 4 (RB4) as a reactive dye. The adsorption studies are carried out at different pH values, different adsorbate concentrations, various adsorbent dosages, different temperature, and contact time in a batch experiments to find the optimum conditions.
