Abstract

Fundamental studies have been made on the uptake of Ni (II) by means of the adsorption with hydrous alumina supported on agar gel to improve the column and batch experiments. Various factors affecting the adsorption, such as pH, the content of hydrous alumina, the break-through capacity, etc, were examined. It was found that at pH 9.0 of the maximum adsorption the material was sufficient to be 2 ml for the complete adsorption of Ni (II) (200μg) by treating 100 ml of the solution, that the desirable content of hydrous alumina was 0.15 m mol/ml and that the break-through capacity for Ni (II) was 3.71 mg/ml. Effect of various kinds of foreign ion was examined. The adsorption percentage was nearly 100% in the range of low concentration-less than 0.05 M-of Na2B4O7, NaCl, Na2SO4, and NH4Cl, but it was decreased remarkably by increasing NH4Cl concentration because of the formation of soluble complex, while it was decreased slightly by other salts. This material may be applied to the uptake of heavy metals in waste water. Furthermore, it is expected that the material may be also employed a new material for column chromatography.
