Abstract

The effect of the acid treatment on the adsorption capacity of aluminum oxides for Mo was examined. The areas of the initial (v o) and limiting (v lim) saturation of neutral and acidic aluminum oxides with hydrochloric acid were determined. The Mo adsorption maximum is attained at the limiting saturation, with the subsequent exponential decrease on approaching the point in which the interaction of the oxide with the acid starts to decelerate, after which the adsorption drastically decreases. In the area close to vo, the Mo breakthrough to the eluate is observed at any adsorbed amount of Mo. The results obtained allow prediction of the acid amount required for the adsorption of the preset amount of Mo.
