Derivation and application of a generalised exchange-adsorption isotherm for the adsorption of hydrophobic compounds on soils

A general adsorption model able to provide a good description of the multilayer ions and molecular compounds under any circumstances is proposed in this paper. In order reach goal, form isotherm was deduced based on Gapon equation classical forms. The with diverse hydrophobicity acid-base characteristics were investigated validated new for four pesticides different soils. capacity energy estimated by found be related organic matter content soil. Great differences parameters (Ai, Ki, ni) among both soils here.
