Araneda, C.; Basualto, C.; Sapag, J.; Tapia, C.; Cotoras, D.; Valenzuela, F. J. (2011)In this paper, the uptake of Cu(II) ions from an acidic aqueous solution using a continuous column packed with microcapsules containing the chelating extractant LIX-860 N-IC was examined. A simple, economical method was ...
