It is observed that ignited beryllium oxide was soluble in concentrated aqueous solutions of beryllium sulphate to the extent of 1 mole of oxide per 2 moles sulphate, saturation being virtually complete within 6 hours at 80 °C. Since the molar solubility of aluminum oxide is much lower under similar conditions, it is suggested that partial resolution of oxide mixtures might be made on this basis.

Among the various heavy metals, arsenic is frequently found in abandoned mine drainage and the environmental fate of arsenic in real aqueous solutions can be highly dependent on the presence of co-existing ions. In this study, removal of arsenate through adsorption on the reused aluminum oxide or through precipitation was investigated in a single and in a binary system as a function of pH and concentration. Different removal behaviors of arsenate were observed in the presence of different cations as well as a variation of the molar ratios of arsenate to cations. Co-operative effects on arsenate removal by precipitation in solution occurred with an increase of copper concentration, while a decrease of arsenate removal resulted in increasing calcium concentration. It was observed that the arsenate removal in the presence of calcium would be highly dependent on the molar ratios of both elements.
