METHOD FOR PRODUCING A RADIOPROTECTOR

摘要

The inventive method relates to the production of a substance having radioprotecting properties. Water solutions of hydroxycarboxilic acids exuded from a natural raw material and contained in said substance are treated with ammonium molibdate. Humic substances can be exuded by treating a humified material with alkaline solutions at standard conditions. Composts, sapropels, moss peat and transition peat, the humus horizon of various soils can be used as the humified material. The humic substances can be produced from oxidised wood lignin by treating it with an oxygen-containing gas in an alkaline medium at a temperature equal to 170+/-20 DEG C and a pressure ranging from 1.9 to 2.5 MPa during 1-3 hours, aftercooling the stock, separating a solid phase from the solution and acidulating it till pH=2-3 is obtained. The treatment with the ammonium molibdate is carried out at a temperature of 40+/-5 DEG C and can be also carried out by exposing to the action of ultrasound having a radiation power of 40 W/cm2, and a frequency of 22 kHz during 4-8 minutes.
