钯离子吸附剂以及使用了该吸附剂的钯的分离回收方法
摘要：
本发明提供一种固-液型钯离子吸附剂，及使用了该吸附剂的钯的选择性分离方法以及回收方法，所述固-液型钯离子吸附剂兼具现有的溶剂提取法中液-液型钯提取剂的提取性能以及选择性，且不需要使用有机溶剂。使用由下述通式(1)或(2)所示的含酰胺的环状硫醚化合物形成的钯离子吸附剂，或使用将下述通式(1)或(2)所示的含酰胺的环状硫醚化合物固定到载体上而获得的钯离子吸附剂，选择性地分离回收钯。[上述式(1)中，R分别独立地表示氢原子、甲基、乙基、碳原子数3～30的直链或支链状的链式烃基、碳原子数3～10的脂环式烃基或碳原子数6～14的芳香族烃基，m表示1或2的整数，n分别独立地表示1～12的整数，L分别独立地表示亚甲基、亚乙基、碳原子数3～8的亚烷基或碳原子数6～14的亚芳基]。[上述式(2)中，R分别独立地表示氢原子、甲基、乙基、碳原子数3～30的直链或支链状的链式烃基、碳原子数3～10的脂环式烃基或碳原子数6～14的芳香族烃基，n分别独立地表示1～4的整数。另外上述式中，L分别独立地表示亚甲基、亚乙基、碳原子数1～8的亚烷基或碳原子数6～14的亚芳基]。
摘要（英）：

Provided are a palladium ion adsorbent for solid-liquid adsorption which has both the extraction performance and selectivity of a palladium extractant for liquid-liquid extraction used in conventional solvent extraction methods and which does not require the use of any organic solvent and a method for selectively separating and recovering palladium using the adsorbent. Palladium is selectively separated and recovered using a palladium ion adsorbent comprising an amide-containing cyclic sulfide compound represented by general formula (1) or (2) or a palladium ion adsorbent comprising a support and, immobilized thereon, an amide-containing cyclic sulfide compound represented by general formula (1) or (2). [In formula (1), Rs each independently represents a hydrogen atom, methyl, ethyl, a C3-30 linear or branched hydrocarbon group, a C3-10 alicyclic hydrocarbon group, or a C6-14 aromatic hydrocarbon group; m is 1 or 2; ns each independently is an integer of 1-12; and Ls each independently represents a methylene group, an ethylene group, a C3-8 alkylene, or a C6-14 arylene.] [In formula (2), Rs each independently represents a hydrogen atom, methyl, ethyl, a C3-30 linear or branched hydrocarbon group, a C3-10 alicyclic hydrocarbon group, or a C6-14 aromatic hydrocarbon group; ns each independently is an integer of 1-4; and Ls each independently represents a methylene group, an ethylene group, a C1-8 alkylene, or a C6-14 arylene.]
