Abstract

С метода се преработват радиоактивни отпадъчни води, съдържащи борни съединения и радионуклиди. Отпадъчната вода се концентрира до сухо чрез изпарение. В следващ, междинен етап на реакцията, при прибавяне на излишък от нисш алкохол с по-дълга въглеводородна верига, например бутилов алкохол, се получава естер на борната киселина, който се отделя от другите остатъци. Съдържащите радионуклиди остатъци се отвеждат и водата, алкохолът и борната киселина се връщат обратно. 10 претенции, 1 фигура
