This Study Explains How the Pyrimidinyloxybenzoic Herbicide Bispyribac Sodium Can Be Broken
Down By Sunlight and Other Sources, Making It Safer For Use In Paddy Fields. Znona2s2o8 Was Studied As A
Photo Sensitizer Oxidant In an Aqueous Suspension to Determine Its Degradation. Bispyribac Sodium
Photocatalysis Was Investigated In Daylight Using Three Different Aqueous Buffer Solutions (Ph 4, 7, And
9). We Also Looked into How Bispyribac Sodium and Its Metabolites Impacted Green Algal Development In
This Study (Pseudokirchneriella Subcapitata). When Compared to Photolysis Experiments, the Results
Demonstrated That the Inclusion of a Photosensitizer Significantly Improved Pesticide Removal. This
Method Also Rapidly Increases the Reaction Rate. Compared to Using Just Zno, the Addition of the Oxidant
(Na2s2o8) Speeds Up the Reaction and Provides Additional Benefits. Degradation of Sodium Bispyribac
Occurs With First-Order Kinetics. Statistics Were Used to Calculate Green Alga Growth Rates (Er) and Yield
Percentages (Ey). There Was a Significant Decrease In Growth Rate Inhibition With Increasing Irradiation
Time.
