Abstract
Procedimiento para la regeneración de ácido clorhídrico por intercambio iónico, que consiste en la filtración en un lecho de arena-carbón de los baños ácidos de decapado, reteniéndose las partículas metálicas y las diferentes sustancias orgánicas incorporadas en el baño, efectuándose a continuación la retención del Zn mediante un lecho de resina aniónica para posteriormente oxidar mediante H{sub,2 O{sub,2 del efluente de salida de la primera columna oxidándose el Fe (II), reteniéndose en una segunda columna el producto obtenido empleándose una resina aniónica.Procedure for the regeneration of hydrochloric acid by ion exchange, which consists of filtering the acid pickling baths in a sand-carbon bed, retaining the metal particles and the different organic substances incorporated in the bath, and then retaining the Zn by means of an anion resin bed to subsequently oxidize by H {sub, 2 O {sub, 2 of the effluent from the first column leaving Fe (II) oxidizing, the product obtained using an anionic resin being retained in a second column.
