Bentazone degradation efficiency and mineralization in water solutions using chlorine dioxidetreatment were evaluated. Double distilled water and a river water sample spiked with bentazonewere studied and compared after chlorine dioxide treatment. Degradation efficiency was determinedusing high-performance liquid chromatography (HPLC). Daphnia magna toxicity testing andtotal organic carbon (TOC) analysis were used to ascertain the toxicity of the degraded solutionsand mineralization degree. Bentazone degradation products were identified using gas chromatographywith a triple quadrupole mass detector (GC-MS-MS). A simple mechanistic scheme for oxidativedegradation of bentazone was proposed based on the degradation products that wereidentified. Decrease in D. magna mortality, high degradation efficiency and partial bentazone mineralizationwere achieved by waters containing bentazone degradation products, which indicatethe formation of less toxic compounds than the parent bentazone and eff...ective removal of bentazonefrom the waters. Bentazone degraded into four main degradation products. Humic acid fromSava River water influenced bentazone degradation, resulting in a lower degradation efficiency inthis matrix (about 10% lower than in distilled water). Chlorine dioxide treatment of water todegrade bentazone is efficient and offers a novel approach in the development of new technologyfor removal of this herbicide from contaminated water.
