Adsorption of zinc ions in water on natural and treated clay has been studied. Natural clay before and after activation was characterized using TGА/DTА techniques and chemical analysis.The effects of various parameters, such as an initial concentration, temperature, pH, contact time and adsorbent concentration, has been examined. It was shown that treated clay is a good adsorbent compared to natural clay for removing Zn2+ ions and can be used instead of expensive adsorbents.

A task about three-dimensional distribution of indignation of temperature in a lithosphere is taken to the decision of two-dimensional task. The equalizations and algorithms of their decisions got as a result of undertaken studies let to conduct the numeral design of the developed convection in the conditions of mantle of Earth, to investigate the thermal cooperating of convective mantle with a lithosphere, to restore distribution of temperature in overhead part of lithosphere of region.
