Изобретение относитс  к технологии очистки кислых растворов от хлор-ионов, например промывных вод сол нокислого травлени .The invention relates to a process for the purification of acidic solutions from chlorine ions, for example, wash water of hydrochloric acid etching.

Известен способ очистки кислых растворов от хлор-ионов путем св зывани  хлор-ионов в труднорастворимую однохлористую медь рра обработке раствора порошкообразной металлической медью.A known method of purifying acidic solutions from chlorine ions by binding chlorine ions to the insoluble copper monochloride, PpA, to the treatment of the solution with powdered metallic copper.

Цель изобретени  - интенсификаци  процесса .The purpose of the invention is to intensify the process.

Дл  этого раствор подвергают электролизу с медными электродами при анодной плотности тока 2-15 а/дм температуре 10-80°С.For this, the solution is subjected to electrolysis with copper electrodes at an anodic current density of 2–15 A / dm at a temperature of 10–80 ° C.

Предложенный способ позвол ет обрабатывать растворы, содержащие до 10 г/л ионов хлора. Раствор, содержащий хлор-ионы, непрерывно пропускают через электролизер.The proposed method allows the treatment of solutions containing up to 10 g / l of chloride ions. The solution containing chlorine ions is continuously passed through the electrolyzer.

В процессе электролиза происходит анодное растворение меди преимущественно в виде одновалентной . На аноде образуетс  рыхлый белый осадок однохлористой меди, котора  самопроизвольно отваливаетс  от анода и скапливаетс  в нижней части электролизера.In the process of electrolysis, anodic dissolution of copper occurs predominantly in the form of monovalent. A friable white precipitate of copper monochloride forms on the anode, which spontaneously falls off the anode and accumulates in the lower part of the electrolyzer.

Па медном катоде выдел ютс  водород и избыточна  медь, не св завша с  с хлором. Hydrogen and excess copper, which are not associated with chlorine, are released from the copper cathode.

За счет выделени  водорода раствор подщелачиваетс , но это не приводит к нарушению нормального хода процесса, так как поступающий на электролиз раствор имеет реакцию или его подкисл ют до электролиза, например, серной кислотой.Due to the release of hydrogen, the solution is alkalized, but this does not disrupt the normal course of the process, since the solution entering the electrolysis has a reaction or acidifies it before electrolysis, for example, with sulfuric acid.

Г1редложенный способ обеспечивает высокую степень использовани  меди - 99,9%, расход электроэнергии при этом незначителен ввиду близости значени  анодного и катодного потенциала.The proposed method provides a high degree of copper utilization - 99.9%, while the power consumption is insignificant due to the proximity of the anodic and cathodic potential values.

Процесс  вл етс  непрерывным, очищенную воду можно использовать в оборотном водоснабжении .The process is continuous, the purified water can be used in the circulating water supply.

Предмет изобретени Subject invention

Способ очистки кислых растворов от хлорионов путем св зывани  хлор-ионов в труднорастворимую однохлористую медь, отличающийс  тем, что, с целью интенсификации процесса, раствор подвергают электролизу с медными электродами при анодной плотности тока 2-15 a/дм, температуре 10-80°С.The method of purification of acidic solutions from chlorins by binding chlorine ions to insoluble copper monochloride, characterized in that, in order to intensify the process, the solution is subjected to electrolysis with copper electrodes at an anode current density of 2-15 a / dm, temperature 10-80 ° C .
