Abstract:

Photocatalytic study was conducted to determine the decontamination deeds of propaquizafop in acidic buffer (pH 4), neutral buffer (pH 7), basic buffer (pH 9) and Milli Q water by ZnO nanoparticle. Photocatalytic reaction was conducted under direct solar light. Propaquizafop residues in water was determined by HPLC-UV detector and calculated the rate constant, DT50 and DT90 values obtained from the data. Consequence of photo catalysis on pH, on amount of photocatalyst, at light intensity, on radical quencher, on sensitizer was studied. ZnO nanoparticle was greatly decontaminating the propaquizafop in water and observed first order reaction rate.
