METHOD OF CLEANING POLLUTED MEDIUM FROM ORGANIC SUBSTANCES Russian patent published in 2010 - IPC C02F1/58 C02F1/32 C02F101/30 

FIELD: chemistry.

SUBSTANCE: cleaning method involves preparation of an initial mixture, adding the mixture to the polluted medium and holding for seven days with natural illumination. The initial mixture is selected from: a nanocomposition No.1 which is a mixture of a powder of iron nanoparticles with particle size of 15-50 nm and powder of nanoparticles of an alloy of nickel and chromium with particle size of 15-50 nm dissolved in nitrobenzene, a nanocomposition No.2 which is a mixture of a powder of nanoparticles of an alloy of nickel and chromium with particle size of 15-50 nm and powder of nanoparticles of quartz with particle size of 50-100 nm dissolved in phenyl cellosolve, a nanocomposition No.3 which is a mixture of a powder of nanoparticles of an alloy of nickel and chromium with particle size of 15-50 nm and 10-20% micellar solution of copper in isooctane solvent with copper particle size of 3-12 nm, dissolved in chlorobenzene, a nanocomposition No.4 which is a mixture of a powder of nanoparticles of an alloy of nickel and chromium with particle size of 15-50 nm an a powder of quartz nanoparticles with particle size of 50-100 nm dissolved in benzonitrile, a nanocomposition No.5 which is a mixture of a powder of quartz nanoparticles with particle size of 50-100 nm and 10-20% micellar solution of silver in isooctane solvent dissolved in benzyl formate.

EFFECT: more efficient purification of water and silt deposits from any types of organic and inorganic pollutants.
