Title (EN) METHOD FOR ELUTING SILVER AND METAL ADSORBED BY ACTIVATED CARBON, AND METHOD FOR RECOVERING METAL AND SILVER EMPLOYING SAME
(FR) PROCÉDÉ D'ÉLUTION DE L'ARGENT ET DU MÉTAL ADSORBÉS PAR DU CHARBON ACTIF, ET PROCÉDÉ DE RÉCUPÉRATION DE MÉTAL ET D'ARGENT L'UTILISANT
(JA) 活性炭に吸着された金及び銀の溶離方法及びそれを用いた金及び銀の回収方法
Abstract:
(EN) Silver and metal adsorbed by activated carbon are effectively eluted. A method for eluting silver and metal adsorbed by activated carbon, in which metal and silver are eluted from activated carbon that has adsorbed at least metal and silver, using a thiosulfate aqueous solution maintained at a pH of less than 7.
(FR) De l'argent et du métal adsorbés par du charbon actif sont efficacement élués. L'invention concerne un procédé d'élution de l'argent et du métal adsorbés au moyen de charbon actif, le métal et l'argent étant élués à partir de charbon actif qui a adsorbé au moins du métal et de l'argent, à l'aide d'une solution aqueuse de thiosulfate maintenue à un pH inférieur à 7.
(JA)  活性炭に吸着している金及び銀を効率的に溶離する。少なくとも金及び銀が吸着した活性炭に対し、pH7未満に保持したチオ硫酸塩水溶液を用いて金と銀とを溶離させる活性炭に吸着された金及び銀の溶離方法。
