Description

верхность 0,3 дм, и катодом из стали 1Х18Н10Т с такой же рабочей поверхностью.surface 0.3 dm, and a cathode of steel 1X18H10T with the same working surface.

Процесс электролиза ведут при плотности тока 20 а/дм и температуре 90°С в течение 2,1 час. Выход по току дл  реакции анодного растворени  меди составл ет 90%; степень катодного восстановлени  хрома (VI) в хром (III) составл ет - 2%. Дл  полного восстановлени  хрома (VI) до хрома (III) в нолученный фосфорнокислый раствор при температуре электролиза ввод т 45 мл 40%-кого раствора формальдегида. В результате получают 300 мл раствора однозамещенного ортофосфатахрома и меди с плотпостью 1,55 г/см.The electrolysis process is carried out at a current density of 20 a / dm and a temperature of 90 ° C for 2.1 hours. The current output for the anodic copper dissolution reaction is 90%; the degree of cathodic reduction of chromium (VI) to chromium (III) is 2%. To completely reduce chromium (VI) to chromium (III), 45 ml of a 40% formaldehyde solution is injected into the phosphoric acid solution obtained at the electrolysis temperature. The result is 300 ml of a solution of monosubstituted orthophosphate copper and copper with a density of 1.55 g / cm.

Аналогичный результат получают, дозиру  исходные реагенты из расчета получени  однозамещенного ортофосфата A similar result is obtained by metering the starting reagents at the rate of obtaining a monosubstituted orthophosphate.

Электрохимический способ получени  однозамещенных ортофосфатов xpOiMa и меди, о тличающийс  тем, что, с целью упрощени  технологии, металлическую медь раствор ют анодно в смеси ортофосфорной и хромовой кислот при плотности тока 10-50а/дм2, предпочтительно 10-40 а/дм, мол рном соотношении , ортофосфорной и хромовой кислот в пределах 2,4-8,4 : 1, предпочтительноThe electrochemical method of producing monosubstituted xpOiMa orthophosphates and copper, in contrast to the fact that, in order to simplify the technology, metallic copper is dissolved anodically in a mixture of orthophosphoric and chromic acids at a current density of 10-50 a / dm 2, preferably 10-40 a / dm, molar ratio, orthophosphoric and chromic acids in the range of 2.4-8.4: 1, preferably

3,3-6,0 : 1, :при температуре 18-100°С, предпочтительно 50-90°С.3.3-6.0: 1,: at a temperature of 18-100 ° C, preferably 50-90 ° C.
