The sample was composed of small grains with an average size of 78 nm. This method could be a useful, inexpensive, and efficient tool for the preparation of Ni-doped CaTiO3 nano-powders. The prepared sample was used for the removal of Cd2+ from water media. Results indicated that Cd2+ removal by Ni-doped CaTiO3 nano-powders was very efficient (100% removal yield) when the pH was adjusted to 4.5, the catalyst dosage amounted to 0.05 g, and the Cd2+ solution concentration was 60 mg.L-1. A pseudo-second-order kinetic model described the kinetics of Cd2+ removal.}, keywords = {CaTiO3 Nano-powders,Ni-Doped CaTiO3,Cd2+ Removal,Wastewater,adsorption experiment}, url = {https://jpst.irost.ir/article_1206.html}, eprint = {https://jpst.irost.ir/article_1206_4e349f8f3314d7715861c36f7bc1ef85.pdf} }
