The alkyl chain was introduced to the surface of silica gel. The new separation material which is loaded N,N-Bis-(2-hydroxyphenylmethyl)-N,N-bis(2- pyridylmethyl)-1.2-ethanediamine on the surface of silica gel was synthesized. The selectivity of metal ions was improved compared with the solvent extraction method when the Ga3+ and In3+ metal ions were separated from acidic solution using new separation material. The separation material was synthesized using silicate which had different length, and it was researched to the adsorption mechanism of Ga3+ and In3+ ions. As a result, it was understood that the relation is not seen in a pore size and the selectivity. The adsorption of Ga3+ and In3+ have been researched as an applied research. As a result, the adsorption mechanism of Ga3+ and In3+ from aqueous solution was similar to the solvent extraction system using C18g separation material, and different to use C12g separation material.
