Catalytic peroxidation of acrylic acid from aqueous solution incorporated with highly active La_0.5Sr_0.5BO₃ (B=Cu, Fe and Ni) perovskite-like catalysts.

ABSTRACT: In the current study, catalytic behaviour of La_0.5Sr_0.5BO₃ (B=Cu, Fe and Ni) perovskite-like catalysts synthesized by sol-gel method were examined in catalytic peroxidation of acrylic acid as a model organic compound and further characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) with energy dispersive X-ray (EDX), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). The effect of various parameters such as catalyst dose, H₂O₂/acrylic acid molar ratio, temperature, pH and initial acrylic acid concentration on acrylic acid and COD removal was studied. The maximum acrylic acid and COD removal of 86.79% and 71.57% were observed at optimu
