Determination of the Dynamics of Organic Solvent Extraction from a Porous Material in a Fixed Granular Bed

Equations describing the extraction dynamics of ethyl carbamate from a porous product using an organic solvent were derived. It is noted that the equations are an adaptation of the mathematical description of the adsorption and ion exchange process to the conditions of the solid-phase extraction process. It is concluded that the developed mathematical model will allow optimizing the process by reducing the amount of extractant and significantly reducing the duration of the process, while maintaining the structural and mechanical characteristics of the product.
