Bentazone degradation efficiency and mineralization in water solutions using chlorine dioxide
treatment were evaluated. Double distilled water and a river water sample spiked with bentazone
were studied and compared after chlorine dioxide treatment. Degradation efficiency was determined
using high-performance liquid chromatography (HPLC). Daphnia magna toxicity testing and
total organic carbon (TOC) analysis were used to ascertain the toxicity of the degraded solutions
and mineralization degree. Bentazone degradation products were identified using gas chromatography
with a triple quadrupole mass detector (GC-MS-MS). A simple mechanistic scheme for oxidative
degradation of bentazone was proposed based on the degradation products that were
identified. Decrease in D. magna mortality, high degradation efficiency and partial bentazone mineralization
were achieved by waters containing bentazone degradation products, which indicate
the formation of less toxic compounds than the pare...nt bentazone and effective removal of bentazone
from the waters. Bentazone degraded into four main degradation products. Humic acid from
Sava River water influenced bentazone degradation, resulting in a lower degradation efficiency in
this matrix (about 10% lower than in distilled water). Chlorine dioxide treatment of water to
degrade bentazone is efficient and offers a novel approach in the development of new technology
for removal of this herbicide from contaminated water.
