The main chemical, biological and physical methods of deactivation of such natural disperse systems as soils and bottom sediments from charged and uncharged pollutants are analyzed. The impact of properties of natural disperse systems and the substances causing their contamination on the expediency of using some specific detoxication method is considered. The peculiarities of ex-situ and in-situ treatment are indicated.

The results are used to assess the applicability of a multistate model with more than two possible adsorption states. For the experiments with single drops, the depletion of surfactant molecules due to adsorption at the drop surface is taken into account.

The aim of the study was to evaluate the combined effect of two widespread xenobiotics, titanium oxide nanoparticles (TiO) and bisphenol A (BPA), on freshwater bivalve Unio tumidus. The specimens were exposed for 14 days to TiCl (Ti, 1.

A model of collision and collection of Brownian submicron particles based on the creation of a convective-diffusion layer near a bubble surface and overcoming the energy barrier created by particle/bubble interaction is developed. Simple analytical expressions describing the rate of collision and collection efficiency are obtained. The collision and collection minimums and the limits of theory applicability are analysed.
