Competitive sorption between 1,3-dichlorobenzene or 2,4-dichlorobenzene or 2,4-dichlorophenol and natural aromatic acids in soil organic matter

Aromatic acids and other small natural organic molecules appear to govern the fate, transport and bioavailability of anthropogenic organic compounds in the environment by occupying and hindering the adsorption sites in soil organic matter (SOM). The selected five aromatic acids namely vanillic, ferulic p-hydroxybenzoic acid, trans-cinnamic and p-coummaric acids yielded nonlinear isotherms yielded nonlinear isotherms, revealing a distribution of site energies in SOM.
