    摘要： To provide a method for recovering a precious metal from a solution containing precious metal ions, an extracting agent or adsorbent used therefor, and a back-extracting agent or desorbent.
    An extracting agent or adsorbent in which precious metal ions are extracted or adsorbed, is brought into contact with a back-extracting agent or desorbent containing a sulfur-containing amino acid derivative represented by the following formula (I):

    wherein R 1 is a methyl group, an ethyl group, a vinyl group, a C 3-8 linear, branched or cyclic hydrocarbon group, or a C 6-14 aromatic hydrocarbon group, R 2 's are each independently a hydrogen atom, a methyl group, an ethyl group, a vinyl group, a C 3-8 linear, branched or cyclic hydrocarbon group or a C 6-14 aromatic hydrocarbon group, and n is 0 or 1, to obtain a solution containing the precious metal ions, which is subjected to a reduction treatment to obtain a precious metal.

    摘要： To provide a solid-liquid palladium ion adsorbent which has both extraction performance and selectivity of a liquid-liquid palladium extracting agent in a conventional solvent extraction method and which does not require use of an organic solvent, and methods for selectively separating and recovering palladium, using it.
    Palladium is selectively separated and recovered by using a palladium ion adsorbent comprising an amide-containing cyclic sulfide compound represented by the following formula (1) or (2), or a palladium ion adsorbent having the amide-containing cyclic sulfide compound represented by the following formula (1) or (2) fixed on a carrier:

    wherein R is each independently a hydrogen atom, a methyl group, an ethyl group, a C 3-30 linear or branched chain hydrocarbon group, a C 3-10 alicyclic hydrocarbon group or a C 6-14 aromatic hydrocarbon group, m is an integer of 1 or 2, n is each independently an integer of from 1 to 12, and L is each independently a methylene group, an ethylene group, a C 3-8 alkylene group or a C 6-14 arylene group;

    wherein R is each independently a hydrogen atom, a methyl group, an ethyl group, a C 3-30 linear or branched chain hydrocarbon group, a C 3-10 alicyclic hydrocarbon group or a C 6-14 aromatic hydrocarbon group, n is each independently an integer of from 1 to 4, and L is each independently a methylene group, an ethylene group, a C 3-8 alkylene group or a C 6-14 arylene group.
