Sorption of selected polycyclic aromatic hydrocarbons on soils in oil-contaminated systems

Polycyclic aromatic hydrocarbons sorbed on soils: A short review of chemical oxidation based treatments

“…The sorption of hydrophobic organic compounds (as in the case of PAHs) onto soils has been widely investigated by a number of authors [4][5][6][7][8][9][10][11].…”

“…oils). The presence of sub-phases in the solid involves a complex mechanism of mass transfer phenomena that are normally studied at the macroscopic scale by means of static or dynamic experiments [9]. In the majority of cases the adsorption of PAHs on soils follows a linear isotherm [8], i.e., the sorption stage is similar to the partition of non-ionic substances between a hydrophobic and a hydrophilic phase.…”

Effect of dissolved organic matter from Guangzhou landfill leachate on sorption of phenanthrene by Montmorillonite

“…Comparing with biodegradation [3], adsorption of PAHs on mineral phases and mineral soil is an efficient remediation process that has decisive effects on their transport, bioavailability [4], and fate in natural environments [5,6]. Clay minerals have a high specific surface area and carry a charge, enabling them to bind and stabilize PAHs.…”

Degradation of anthracene, pyrene and benzo[a]-anthracene in aqueous solution by chlorine dioxide

“…In a word, the efficiency of bioremediation depends on environmental conditions and in general the process is slow. Due to the microbial resistance of most PAHs, remediation has generally been performed using alternative physico-chemical approaches, such as oxidation [12,13] , direct or ultraviolet photolysis [14,15] , ultrasonic treatment [16,17] and adsorption [18,19] , and so on.…”
