В исходный раствор,, додержащкй 2,2 г/л меди и 10,2 г/л ЭДТА (рН 2), при перемгашваню ввод т конценгрирсжанную серную кислоту до общей кислотности раствора 3,1 г-экв/л., перемешивают в течение трех часов и отстаивают 8 ч.II p m e p. Into the initial solution containing 2.2 g / l of copper and 10.2 g / l of EDTA (pH 2), with distilled sulfuric acid, the total acidity of the solution is 3.1 g / eq / l and mixed for three hours and defend 8 hours
При этом из раствора кристаллизуетс в виде белых кристаллов. Из исходного раствора объемом 1,5 л получено 15,3 г ЭДТАAt the same time, the solution crystallizes in the form of white crystals. 15.3 g of EDTA were obtained from the initial 1.5 l solution
