Article Synopsis
- Ozone, a strong oxidizing agent, was used in this study to effectively degrade endosulfan (89% efficiency) and lindane (43%) at an optimal dosage of 57 mg min(-1)
- The degradation process was significantly influenced by pH levels, with a pH of 10 being optimal for endosulfan degradation (93% efficiency) and a pH of 12 for lindane (82% efficiency)
- Kinetic analysis showed that both compounds followed first-order kinetics, and gas chromatography mass spectroscopy identified degradation products, suggesting mechanisms like ring fission for the chemicals involved.
Article Synopsis
- The study evaluated a bimetallic system (Mg 0/ZnCl 2) for effectively dechlorinating the pesticides endosulfan and lindane in water.
- The addition of acetone improved the solubility of the pesticides, with optimal water-to-acetone ratios of 2:1 for endosulfan and 1:1 for lindane, enabling higher removal rates.
- The reactions, enhanced by H+ ions, achieved 96% and 98% removal for endosulfan and lindane respectively, with first-order kinetics observed across different concentrations and metal doses.
