چکیده
|
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.
