Data-driven analysis of photocatalytic degradation of pararosaniline using green synthesized SrO nanoparticles

Pararosaniline is an extensively used carcinogenic dye whose presence in waterbodies poses serious health risk and hence its photocatalytic degradation is an environmentally relevant dataset. The data reported here highlights the synthesis, characterization and kinetics involved in photocatalytic behaviour of SrO during the degradation of cationic triarylmethane dye pararosaniline. SrO nanoparticles were synthesized by using Plant extract as green fuel from Leucas Aspera and characterized by X-ray diffractometers (XRD), Field emission scanning electron microscopes (FESEM), Fourier transform infrared (FTIR), and UV/vis spectrometer. XRD confirmed the crystalline character of SrO matching with JCPDS database card no. 06-520, FESEM shows the presence of nano-rod like structure with rounded edges having average particle size between 23.20nm-95 nm and FTIR confirming the stretching and bending vibrations of Sr-O bond. The Degradation of pararosaniline was spectrophotometrically examined in the presence of sun light by varying catalyst concentration, dye dosage and pH within 60 min. The highest degradation efficiency 89 % of Pararosaniline was obtained at pH=12 with concentration of catalyst 50 mg and concentration of dye 10 ppm. These findings show the potential application of synthesized SrO nanoparticles for environmental remediation.
