Assessment of the relations between the spectroscopic characteristics of soils and their ability to adsorb organic pollutants

The inorganic components of the soils play an important role also in the absorption of the apolar compounds, and as the polarity (or polarizability) of the organic compound increases, the humic materials of the soil, or rather their polar functional groups take the dominant role in the absorption of the pollutant. The absorption and desorption of three apolar compounds were practically not influenced by the presence of other pollutants in the soil, and this phenomenon was also independent from the extracting agent. However, in the case of polar diuron, the presence of other pollutants can result in decrease of mobility.
