degradation and adsorption behavior of dibutyl phthalate

DEGRADATION AND ADSORPTION BEHAVIOR OF DIBUTYL PHTHALATE IN

The degradation and adsorption behavior of dibutyl phthalate (DBP) in methanogenic phase refuse was investigated through laboratory microcosm experiments. The results showed that the half-life of DBP in the sterilized refuse was 5.9 times higher than in unsterilized samples, but that it decreased by 35.8% when dominant bacterial strains were added.

Sorption is a fundamental process controlling the transformation, fate, degradation, and biological activity of hydrophobic organic contaminants in the environment. We investigated the kinetics, isotherms, and potential mechanisms for the sorption of two phthalic acid esters (PAEs), dibutyl phthalate (DBP

Degradation and adsorption behavior of dibutyl phthalate in

The behaviors of organic compounds such as dibutyl phthalate (DBP) or dioctyl phthalate (DOP) on a Si substrate are investigated by gas chromatograph and mass analysis (GC–MS). DBP or DOP source is set in a chemically clean booth, and organic amount is measured in air and on the substrate.

Fe-Activated Peroxymonosulfate Enhances the Degradation of

Soil contamination by organic compounds has received worldwide concern for decades. Here, we found that dibutyl phthalate (DBP) could be degraded on moist quartz sand (QS, crystal, a typical soil constituent) during stirring, and the removal rate reached 57.2 ± 3.1% after 8 h of reaction. The introduction of peroxymonosulfate (PMS) and zerovalent iron (Fe0) substantially improved the
