Spent electroplating baths, waste pickle liquors, etching solutions and rinse waters from electroplating units and steel finishing operations are complex solutions containing acids and several hazardous metals. It is compulsory, for environmental and economic reasons, to treat these solutions for recovering acid, metals and\/or reusing these solutions\/waters. This article is a review on the characterization of the wastes that are generated in electroplating industry, steel processing and copper etching in printed circuit boards manufacture, as well as on the treatment and regeneration methods of such streams. Various techniques, such as neutralization, crystallization, evaporation, pyrohydrolysis, electrodialysis, ion exchange, classical solvent extraction and membrane-based solvent extraction are presented, their advantages and disadvantages being scrutinized.<\/jats:p>","DOI":"10.1515\/psr-2018-0024","type":"journal-article","created":{"date-parts":[[2018,4,12]],"date-time":"2018-04-12T08:48:16Z","timestamp":1523522896000},"source":"Crossref","is-referenced-by-count":7,"title":["Electroplating wastes"],"prefix":"10.1515","volume":"3","author":[{"given":"M.
