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.
