Degradation of haloacetic acids with the Fenton-like and analysis by GC-MS: use of bioassays for monitoring of genotoxic, mutagenic and cytotoxic effects

A method was developed to evaluate the degradation of haloacetic acids in water by a heterogenous Fenton-like process catalyzed by cobalt-doped magnetite nanoparticles, extraction of the contaminants by liquid-liquid extraction, and analysis by gas chromatography-mass spectrometry

A method was developed to evaluate the degradation of haloacetic acids in water by a heterogenous Fenton-like process catalyzed by cobalt-doped magnetite nanoparticles, extraction of the contaminants by liquid-liquid extraction, and analysis by gas chromatography-mass spectrometry
The developed method was efficient in the degradation of HAAs, with the following degradation values: 63%, 62%, 30%, 39%, 37%, 50%, 84%, 41%, and 79% for monochloroacetic acid, monobromoacetic acid, dichloroacetic acid, trichloroacetic acid, bromochloroacetic acid, dibromoacetic acid, bromodichloroacetic acid, dibromochloroacetic acid, and tribromoacetic acid compounds, respectively
It was possible to verify the effectiveness of the developed method and its potential as a proposal for environmental remediation
