Behavior of Beryllium Sulfate in Hard and Soft Water

Abstract

The interaction of beryllium with hard and soft water represents the first phase of a study of beryllium effects on water and fish. The pH of BeSO4 in soft water is significantly lower than in hard water over the concentration range from 0.01 to 100 mg/l Be(2+). An insoluble complex forms only in hard water within a limited beryllium concentration range. Water hardness per se is a significant determinant of the pH of beryllium solutions. The amount of NaHCO3 needed to buffer varying amounts of concentrated (acidic) beryllium solutions is compared on a molar basis between soft and hard water. Beryllium has no effect on the hardness or dissolved oxygen content of either test water, but shows greater changes in conductivity of soft water than hard water.
