AbstractAbstract
[en] A method of increasing the degree of boron concentration durino. its sorption from solutions using styrene copolymer with divinyl-benzol with aminomethane tris-(oxymethyl) groupings as a sorbent, is suggested. Sorption is performed on the sorbent preliminary treated by methanol taken in the amount of 2-3 volumes per 1 volume of sorbent or 1-2 hours. Desorption is performed by 0.3-0.4 N solution of H2SO4 at the volumetric ratio of H2SO4 degree of boron absolute solution: sorbent being equal (2:-3):1. The degree of boron absolute concentration by the above method is 0.004 at 98-100% degree of boron extraction
