Annotation: There is a model of extraction/re-extraction operations in the box-type extractors on the basis of differential equations of material balance and static with the boundaries the pHindex. The pH must be fixed within limits for the effective separation of hetero–extracting compounds. The algorithm of calculation is proposed for this dynamic model, which is shown in the cascade of box-type extractors.
