Abstract
Изобретение относится к области защиты металлов от коррозии в воде и может быть использовано для ингибирования коррозии в замкнутых системах стальных трубопроводов. Способ защиты стали от коррозии в воде состоит во введении в коррозионную среду 10-30 мл/л водного экстракта щирицы Amaranthus retroflexus L., полученного путем экстракции сухой травы в воде при массовом соотношении 4:10 при температуре 70-90°С в течение 1-3 ч, с последующей фильтрацией.Технический результат изобретения состоит в повышении устойчивости к коррозии до 8,4 раз с использованием эффективного и экологически безопасного ингибитора на основе водного экстракта сухой травы щирицы.
