摘要： Chelating agents on which metals such as uranium have been adsorbed are brought into contact with an eluent of aqueous solution containing reducing agents and basic compounds, until the metals are eluted. The elution is effected with large speed without degradation of the chelating agents. Preferred chelating agents are rather stable under basic conditions but not under acidic conditions, for example, those having = NOH group in their molecules. The reducing agents and basic compounds in the eluent are, for example, sulfurous acid or salts thereof and sodium hydroxide, respectively.

摘要： Rare metals are recovered in high yields by contacting a strongly acidic solution containing at least one rare metal selected from the group consisting of gallium, uranium, molybdenum, rubidium, cesium, strontium, yttrium, niobium, tantalum, tungsten, ruthenium, osmium, rhodium, iridium, palladium, platinum, thallium and europium with a chelate resin having at least one phosphorus atom-containing functional group selected from phosphine group, phosphonium salt group, phosphinic acid group, phosphinic acid ester group, phosphonic acid group, phosphonic acid ester group and metal salts of these acids.
