%X The removal of aniline blue dye from aqueous solutions using the A-site doped perovskite Ce<sub>1-x</sub>Bi<sub>x</sub>CrO<sub>3</sub> (x = 0, 0.5, 1) was investigated. The perovskite oxides were synthesised using Sol-Gel method and characterised by conventional powder X-ray diffraction technique. The X-ray diffraction measurements suggested that doping with Bismuth Ion influences both the crystal structure and the particle size of the oxides, and consequently affects the adsorption properties. It was found that both CeCrO<sub>3</sub> and Ce<sub>0.5</sub>Bi<sub>0.5</sub>CrO<sub>3</sub> compounds are orthorhombic and have approximate particle size of 87 and 36 nm respectively, whereas BiCrO<sub>3</sub> oxide has rhombohedral space group symmetry and the particle sizes are less than 49 nm. The batch mode study demonstrated that the removal capacities of Aniline Blue at 150 min and pH = 4.3 for Ce<sub>0.5</sub>Bi<sub>0.5</sub>CrO<sub>3</sub>, CeCrO<sub>3</sub> and BiCrO<sub>3</sub> are 779.67, 705.45 and 440.18 mg/g respectively. The results reflect the influence of the A site doping on the adsorption properties of the oxides. The removal of Aniline Blue was found to be negatively correlated with temperature and pH.
