Considers the results of laboratory modeling on research of the adsorption properties of dispersed rocks in relation to heavy metals associated with technogenesis the example of nickel (Ni). It presents data on the adsorption element by samples of various lithological varieties of rocks that form the subsoil strata of Rostov-on-Don city. Are determined mobile forms of Ni; evaluated the intensity of the adsorption process, lists the factors that determine changes in the Ni content of the section. The obtained experimental scientific information is important in solving the environmental, health and social and engi-neering-geological problems.

The article presents the investigation of ultrasonic treatment influence on the size of the stearylamine floccules in the aminobutyric emulsion and on the stability of received emulsions. It was found that the amine floccules in the original aminobutyric emulsion have a bimodal size distribution with small particles predominantly 900 nm and large particles with size of 5500 nm or more. It was identified that ultrasonic treatment leads to decrease the stearylamine floccules size in 13-25 times, dimensions of obtained floccules are between 35 and 220 nm. The dynamics of size changes of stearylamine floccules was studied. The stearylamine floccules were obtained in aminobutyric emulsions after the ultrasonic treatment with an intensity of 15-30 W/cm2. It was found that after ultrasonic dispersion the process of amine floccules agglomeration takes place, the duration of this effect depends on the intensity of treatment.
