“…reported in previous studies. 7,25 The overall adsorption time is relatively long, which is inuenced by the altered conditions of the soil aer inltration. To ensure the adsorption equilibrium, the batch adsorption experiment was chosen to be carried out for 48 h. The kinetic changes in 1,2-DCA adsorption in the presence of FA and HA are shown in Fig.…”

“…It may exist in several physical forms with varying bioavailability in natural waters, such as watersoluble state, associated state with suspended particles, and solubilized state with organics. [6][7][8] The interaction of pollutants and soil grains in the environment is an essential process for their environmental fate and signicantly inuences their removal from soil. The removal of the hydrophobic organics from soils is rather complex due to their low solubility and inclination to adhere to colloids and organic matter in the soil.…”

“…The data confirmed the prevalent role of the hydrophobic interactions in the humic acids-organic molecules interaction. Tang et al [98] analysed the sorption of benzene in function of temperature, pH, and ionic strength. The sorption isotherms showed that sorption of benzene on HA is exothermic and there was no obvious effect of ionic strength on benzene sorption, suggesting that the sorption process is not controlled by ion exchange or electrostatic interactions.…”

Sorption of Organic Pollutants by Humic Acids: A Review

et al. 2020

Humic acids (HA) are promising green materials for water and wastewater treatment. They show a strong ability to sorb cationic and hydrophobic organic pollutants. Cationic compounds interact mainly by electrostatic interaction with the deprotonated carboxylic groups of HA. Other functional groups of HA such as quinones, may form covalent bonds with aromatic ammines or similar organic compounds. Computational and experimental works show that the interaction of HA with hydrophobic organics is mainly due to π–π interactions, hydrophobic effect and hydrogen bonding. Several works report that sorbing efficiency is related to the hydrophobicity of the sorbate. Papers about the interaction between organic pollutants and humic acids dissolved in solution, in the solid state and adsorbed onto solid particles, like aluminosilicates and magnetic materials, are reviewed and discussed. A short discussion of the thermodynamics and kinetics of the sorption process, with indication of the main mistakes reported in literature, is also given.

“…The mass transfer of PAHs and BTEX in horizontal and vertical directions can be divided into three types of pollution: low (<200 μg kg −1 ), medium, and high pollution (>200 μg kg −1 ) areas. 2 At present, there are insufficient data to show the extent of contamination of these compounds in soils in different regions of the world. Manmi et al 3 collected soil samples from the vicinity and surrounding area of petrol stations and oil refinery companies in the city of Sulaymaniyah in north-eastern Iraq for contamination assessment.…”
