Title:
PALLADIUM SOLID PHASE EXTRACTION MATERIAL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2017205745
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a palladium solid phase extraction material high in selectivity to palladium and a manufacturing method therefor, and a solid phase extraction process for separating and recovering palladium and platinum.SOLUTION: There are provided a novel palladium solid phase extraction material which is an adsorbent carrying extraction agent dialkyl sulfide extremely high selectivity to palladium on a graft chain to which an alkyl thiol is introduced as a hydrophobic group, not only palladium adsorption function by carried extraction agent, but also thiol part to which the graft chain is introduced becomes to involve in palladium adsorption and large adsorption volume and adsorption rate are obtained, and a manufacturing method therefor. There is provided a solid phase extraction process for separating and recovering palladium and platinum elements from a palladium and platinum mixed solution by eluting palladium from an adsorption material by using potassium thiocyanate from a solid phase extraction material to which palladium is adsorbed.SELECTED DRAWING: Figure 1
