NiCl₂용액으로부터 γ-Alumina에 nickel을 함침시킨 후, 활성물질인 nickel의 농도분포를 electron probe microanalysis（EPMA）에 의하여 측정하였다. Nickel의 분포 및 담지량을 용액의 초기 pH, 농도 및 온도와 담체의 전처리 조건을 변화시킴으로서 조절될 수 있음이 실험적으로 밝혀졌으며 Ni/γ-Alumina계의 담지메카니즘은 세공내 용액의 용해도차에 의한 침적현상으로 만족스럽게 설명될 수 있었다.

After impregnating nickel from NiCl₂ solution onto γ-alumina, the concentration profile of nickel, an active material was measured by an electron probe micro-analysis（EPMA）. Experimental results showed that the distribution and amounts of nickel could be controlled by changing initial pH, concentration and temperature of the solution, and pretreatment conditions of the support. The impregnation mechanism of Ni/γ-alumina system could be explained satisfactorily by the deposition due to difference in solubilities of the active material in the solution which exists in the pore.
