Dissipation of Fluazolate in Water at Different pH Levels

A laboratory experiment was conducted to study the degradation of fluazolate (JV-485) in water at acidic, neutral and basic pH at the rates of 0.5 (T₁) and 1.0 (T₂) μg mL⁻¹. Water samples collected on 0(1 h), 2, 5, 8, 11, 14 and 17 weeks after treatments were processed for residues of fluazolate by GC-ECD capillary system. In 17 week study, dissipation was almost 99% at all the three pH levels in both the treatments. The degradation pattern of fluazolate in water samples indicated negligible effect of pH. The half-life periods observed were 18.3–18.8 days at pH 5.2, 17.8–19.0 days at pH 7.0 and 19.7–21.5 days at pH 8.2 for T₁ and T₂ doses, respectively. Dissspatton occurred in three distinct phases in water.
