Known methods of sorption extraction of radioactive and toxic contamination of soil, natural and industrial waters [Patent N 1814422, MKI G 21 F 9/12, B N 21, 1996, Patent N 1829718, MKI G 21 F 9/14, BI N 19, 1996 , Patent N 2062518, MKI G 21 F 9/12, B N 17, aceste sorbents of inorganic substances.

The disadvantage of these solutions is the low degree of purification of the soil, natural and industrial waters. The known method of sorption removal of radioactive elements from natural and industrial waters [Patent N 2065629, MKI G 21 F 9/12, B N 23, 1996], based on the extraction of the radioactive element using sorbent-vermiculite.

The disadvantage of this method is the low quality of purification from radioactive elements in the soil, natural and industrial waters with inorganic sorbent vermiculite and proprienitrile. However, in the publicly available information sources not detected description of sorption extraction method exactly thorium from the soil, natural and industrial waters. Therefore, the claimed invention has no analogues. The invention is aimed at improving the quality of sorption of thorium from the soil, natural and industrial waters. This is achieved due to the fact that the extraction of thorium is carried out using a porous composite material comprising vermiculite, activated carbon, glauconite, dextrin with an equal ratio of components.

An example of performing the method.

Plastic frame with two sides has a grid of polymeric materials with a cell of 0.1 mm, between which poured composite material comprising vermiculite, activated carbon, glauconite, dextrin with an equal ratio of components with a filter area of HH see the Top of the filter is closed with a lid that snaps on the side walls. The cover has a handle for lifting when changing filters. Connection filters each other is by using the tool joints. Experiments using this method of extraction of thorium from the soil, natural and industrial waters run directly on the infected area.

Comparative results are summarized in the table.
