Project summaryThe project aim is:
To study sorption properties of natural flins and “flint" water on removal of radionuclides and toxic substances from natural waters and organisms.
Atomic weapon tests carried out on a substantial scale in 50s-60s of the past century, disaster at Chernobyl atomic power plant have stimulated the scientists to develop the medicine capable to remove the radioactive nuclides from the human body.
Of all the variety of developed medicine, the complexons play special role in the binding of radioactive nuclides. The complexons are multidentant chelating compounds to constitute from cycle structures.
Analysis of chemical formulas of these compounds shows, that free valencies of oxygen and nitrogen are formed in the complexons and they bind the radioactive nuclides.
However there are a number of limitations for the use of the complexons. The point is that whenever the radioactive nuclide penetrates into the human body there is a primary depot of radioactivity: lungs and digestive tract under inhalation entry, gastrointestinal tract under peroral pollution, and polluted tissues of the wounds.
Resorption of the radioactive isotopes from primary depot may be increased substantially by the use of the complexons, removing radioactive substances from the places of the primary accumulation. Thus it is impossible to take the complexons internally before radiator is removed from the gastrointestinal tract. There are some other restrictions to use such medicines.
At the same time the long-term investigations of the “flint” water properties, carried out by our laboratory, demonstrated that considerable effect in removing of the radioactive cesium and strontium from the human body was possible without any other negative effects in vital functions, although this binding effect is not that strong as the one due to the complexons.
Teams of the scientists participating in the project are experts in various areas of the theory and practice of water-treatment - in the field of theoretical and applied researches of water structural characteristics; in the field of biotesting water on alive organisms; in the field of analytical chemistry of water. Research laboratories of organizations - executors of the project are equipped with sufficiently modern scientific and technical equipment, allowing to solve the tasks posed in the project.
The project duration is three years; at project implementation the following tasks will be solved:
1.1. Investigation of natural flint deposits in Kyrgyzstan, Tajikistan and in Ukraine.
1.2. Sampling and investigation of mineral content and structural characteristics of natural flints from volcanogenic and flint rocks of different deposits.
2.1. Development of methods on refine of flint and on obtaining the sorbents with the given sizes of micropores.
2.2. Study of sorption properties of dispersed flints.
3.1. Working out the methods of obtaining of two kinds of flint water and development of pilot installation for production of two kinds of flint water.
3.2. Tests of flint water activity on removing of radionuclides and toxic elements from biological objects.
The offered project meets to ISTC basic purposes, as more 50 % of scientists and the experts participating in research activity within the framework of the project, have been connected to the weapon.
The project gives scientists and to experts from Republics of Tajikistan, Ukraine and Belarus, connected with development of the weapon, an opportunity for reorientation of the efforts to peace activity.
The project is devoted to the decision of scientific and technical problems of a world level, therefore the project promotes integration of scientists of Tajikistan, Kyrgyzstan and Belarus in the international scientific community.
Area of researches of the project - applied and basic researches in the field of geology, hydrology and meteorology.
Developed as a result of performance of the project approaches, technical decisions and the scientific information can become a subject of patenting and sharing with the countries participating in financing of works and foreign collaborators. It is supposed cooperation with foreign collaborators on issue of an exchange of the scientific and technical information in a way of carrying out of workshops and joint conference; joint testing of the received samples and preparation of joint publications are possible also.
