Evaluation of matrices for the sorption and biodegradation of phenanthrene

Static and dynamic sorption of phenanthrene in mangrove sediment slurry

“…The present study together with previous research proved that the Freundlich model was a better model to illustrate the static sorption behavior of PAHs onto soil/sediment than linear or Langmuir isotherm models [8,9,12,13]. This may be due to the fact that adsorption of PAHs was mainly due to physico-chemical binding onto heterogeneous surfaces of organic matter and clay in soil/sediment.…”

“…The static sorption behavior of PAHs onto soil/sediment has been described by three models. They are the linear model [6,7], the Freundlich model [8,9] and the Langmuir model [10,11]; and these models were evaluated under different situations [12,13]. Salinity was found to be one of the significant factors affecting the biodegradation of PAHs [14][15][16][17].…”

Adsorption of phenanthrene on activated carbon increases mineralization rate by specific bacteria

“…A previous study [19] has shown that the presence of AC improved PHE mineralization by a Burkholderia sp. strain compared to treatment without AC.…”

“…Solution activity was measured by liquid scintillation counting on 1 ml of solution mixed with 10 ml of Ultimagold ® (PerkinElmer) on a Tricarb 1900CA (Perkin-Elmer). The contact time between the PHE solution and AC was 48 h [19]. Glass tubes closed by Teflon stoppers were used for all experiments.…”

Desorption experiments and modeling of micropollutants on activated carbon in water phase: application to transient concentrations mitigation

“…In this case, major contaminants are hydrocarbons (BTEX, PAHs), chlorinated solvents and phenolic derivatives (Leglize et al 2006). Very few researches have been reported on desorption of a fixed-bed column caused by the variation of contaminant loading in water phase.…”
