The alkyl chain was introduced to the surface of silica gel. The new separation material which is loaded extraction reagent on the surface of silica gel was synthesized. The selectivity of metal ions was improved compared with the solvent extraction method when the transition metal ion was separated using new separation material. It was considered that the reason of improving selectivity of metal ions was a hole of silica gel. The separation material was synthesized using silicate which had different pore size, and it was researched to the adsorption of metal ions. As a result, it was understood that the relation is not seen in a pore size and the selectivity. The adsorption of Ga and In have been researched as an applied research. As a result, the adsorption mechanisu of Ga and In from aqueous solution was similar to the solvent extraction system.

将烷基链引入硅胶表面。合成了硅胶表面负载萃取剂的新型分离材料。采用新型分离材料分离过渡金属离子时，与溶剂萃取法相比，金属离子的选择性有所提高。认为硅胶的孔是提高金属离子选择性的原因。以不同孔径的硅酸盐为原料合成了分离材料，并对其对金属离子的吸附性能进行了研究。结果，可以理解的是，在孔径和选择性中看不到该关系。作为应用研究，对Ga和In的吸附进行了研究。结果表明，该体系从水溶液中吸附Ga和In的机理与溶剂萃取体系相似。
