Nanotechnology is a field of fundamental and applied science and technology dealing with a combination of theoretical substantiation, practical methods of research, analysis and synthesis, as well as methods for the production and application of products with a given atomic structure through controlled manipulation of individual atoms and molecules. In the Address of the President of the Republic of Kazakhstan to the people of Kazakhstan Strategy "Kazakhstan-2050" New political course of the state, the leader of the nation, N.A. Nazarbayev, defines 10 tasks that Kazakhstan faces, one of which is the transition of Kazakhstan to the third industrial revolution. Nanotechnology is one of the branches of the industrial revolution. In the modern world, over the past few years, there has been a rapid development of nanotechnology. The peculiarity of nanotechnology lies in the possibility of their application in an unlimited sphere; therefore they are the basis for a completely new technological order of the economy. Сonsequently, its development in the country is regarded as a particularly important sphere of science. Usage of nanotechnology products will save on raw materials and energy consumption, reduce emissions to the atmosphere and, as a result, will contribute to sustainable economic development.

The object of the study was water and bottom sediments of the lake Balkyldak of Pavlodar region, contaminated by mercury wastes.The purpose of the work is the creation of innovative cost-effective technologies for deep cleaning of aqueous media from mercury to the level of 1-10 parts per trillion, which will be tested for the cleaning of the lake Bylkyldak facilities in Pavlodar region.
