SEPARATION OF COPPER FROM ACIDIC ETCHING SOLUTIONS

Popis výsledku v původním jazyce

This study deals with the issue of copper separation from acidic etching solutions formed during the process of production of printed circuit boards (PCBs)fortheelectricaland electronic industries.The article describes the selected methods of copperseparation and summarizes the results of an experiment,in which the efficiency of copper recovery from the depleted acid solutions by the cementationand precipitation method was verified. In the process of cementation, iron in the form of metallicswarf was used as a precipitant. To verify the efficiency of the precipitation method, CaCO3limestone,Ca(OH)2calcium hydroxide and NaOH solution were used. During the measurement, the amount of Cu in the solution was observedfor both methods in dependence on time, temperature,and pH.
