Предложен новый способ обработки травильного средства, обеспечивающий удобство операций, снижение стоимости содержания и сооружения, а также надежность и эффективность использования газообразного хлора, получаемого в закрытых системах. Способ состоит из следующих этапов. Обработка травильного средства, содержащего хлорид меди (I) или хлорид железа, содержащий медь, посредством электролиза с использованием диафрагмы для удаления осажденной в катодной камере меди; подача газообразного хлора, образующегося в анодной камере, в другое травильное средство, уже использованное в травильном процессе, и таким образом делая пригодным травильное средство к регенерации.A new method for treating an etching agent is proposed, providing convenience of operations, reducing the cost of maintenance and construction, as well as the reliability and efficiency of using chlorine gas produced in closed systems. The method consists of the following steps. Treatment of an etching agent containing copper (I) chloride or iron chloride containing copper by electrolysis using a diaphragm to remove copper deposited in the cathode chamber; supplying chlorine gas generated in the anode chamber to another etching agent already used in the etching process, and thus making the etching agent suitable for regeneration.
