AB  - The sorption behaviour of 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol 
      (2,4,6-TCP), 2,3,4,5-tetrachlorophenol (2,3,4,5-TeCP) and pentachlorophenol (PCP) 
      with an aquatic humic sorbent (HS) was examined in their single and mixed 
      solutions at different acidities (pH 3, 5.5 and 7). The binding capacities and 
      equilibrium coefficients (K(OC)) obtained were fairly close to the literature 
      values but still underline HS's structural and steric influence on the sorption. 
      The most acidic carboxylic (COOH) groups of the HS structure have unquestionably 
      an essential role in the sorption. The amounts of different chlorophenols bound 
      onto the constant quantity of the aquatic HS were in reality very low 
      demonstrating that the amount of the dissolved organic carbon (DOC) in the 
      environment plays a greater role than the value of K(OC). The ability of the 
      aqueous phase to force chlorophenols to associate with the HS becomes at more 
      neutral acidities weaker and weaker and other binding mechanisms become favoured 
      in comparison to hydrogen or hydrophobic bonds. Sorption isotherms were 
      constructed from sorption data, and conformity to a linear model, non-linear 
      Freundlich equation and Langmuir equation was checked.
