| Popis: | Materials by the modified proteic method based on calcium doped LaMnO3 and LaNiO3, with perovskite structure were prepared. The X-ray diffraction patterns revealed the presence of the perovskite phase in all materials, whose specific surface area values varied between 27 and 37 m2.g-1. The materials presented efficiency for the removal of Congo red dye and those with site B occupied by nickel presented better adsorptive efficiency. The incorporation of calcium on LaMnO3 or LaNiO3 materials caused an improvement in the performance of the materials for the dye removal from water. The materials maintained perovskite structure after the adsorption tests, allowing their reuse in new adsorption tests with high efficiency. |
