Dynamic Preconcentration of Organic Substances on Nonpolar Adsorbents

The possibilities of using dynamic adsorption preconcentration in the determination of organic substances were discussed. The effect of thermodynamic and kinetic factors on the extraction of organic compounds from aqueous solutions was considered. The main classes of adsorbents were presented, and the relationship between the adsorbent properties and the efficiency of preconcentration was discussed. Examples of using dynamic adsorption preconcentration for the determination of a wide spectrum of substances were given.
