著者：Parajuli, Durga; Kawakita, Hidetaka; Inoue, Katsutoshi; Ohto, Keisuke; Kajiyama, Kumiko.題名： Persimmon peel gel for the selective recovery of gold.発表情報： Hydrometallurgy 巻: 2007 ページ: 133-139キーワード：persimmon peel, gold, adsorption, selectivity概要：抄録：The use of persimmon peel gel for the recovery of Au(III) from aq. chloride medium was investigated. By comparing with the adsorption of some other metal ions, the gel was found to be selective only for Au(III). The XRD anal. and the digital micrograph of the gel taken after adsorption supported the formation of gold particles during adsorption process. High selectivity and capacity of the gel for Au(III) is assocd. with the redn. of Au(III) to elemental form. Comparative study of redn. of Au(III) by typical tannin rich materials, green tea and oolong tea, and by various org. acids clarified the involvement of polyphenolic groups in the redn. of Au(III) during adsorption. Innovative use of this novel adsorption gel can fulfill the need of cost effective and environment friendly mean for the recovery of valuable metals.英語フィールド
