Description

Очищенный раствор содержит следы меди и кадми .The purified solution contains traces of copper and cadmium.

Пример. Цинковый раствор, содержащий 250 мг/л меди и 450 мг/л кадми , имеющий температуру 45°С и рН 4,4, пропускают со скоростью 0,15 м/сек через постель из цинковых гранул, с размерами от 1 до 5 мм.Example. A zinc solution containing 250 mg / l of copper and 450 mg / l of cadmium, having a temperature of 45 ° C and a pH of 4.4, is passed at a speed of 0.15 m / s through a bed of zinc granules with dimensions ranging from 1 to 5 mm.

Очищенный раствор после отсто  в течен.ие 2 мин имеет рН 5,2 и содержит следы меди и кадми .The purified solution after settling for 2 minutes has a pH of 5.2 and contains traces of copper and cadmium.
