Claims (1)

Предлагаемый безопасный, энергосберегающий способ извлечения (или очистки) тиоцианата из большого количества сточных вод (или водного раствора, содержащего тиоцианат) с помощью обратной осмотической мембраны, которая удерживает от 10 до 70% хлорида натрия, заключается в извлечении тиоцианата из сырья без снижения концентрации.The proposed safe, energy-saving method of extracting (or purifying) thiocyanate from a large amount of wastewater (or an aqueous solution containing thiocyanate) using an osmotic membrane that holds from 10 to 70% sodium chloride is to remove thiocyanate from the raw materials without reducing the concentration.
