- Abstract
Experiments were carried out to simulate the transformations of anaerobic freshwater chemistry at aeration. Quantitative characteristics of the passage from dissolved into suspended state in the course of aeration were obtained for Fe, Mn, Co, Ni, Cu, Zn, Cd, Ag, Rb, Cs, Sr, Ba, Be, Al, Ga, Cr, Ti, Zr, U, La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, B, V, Ge, As, Mo, and W. The decrease in the concentration of dissolved forms was found to be maximal for Fe and Mn, reaching 0.03 and 0.2 mg/L, respectively; these values correspond to the solubility of newly-precipitated oxihydrates of those elements. Among other elements, a high degree of removal is typical of elements-hydrolysates (Cr, Zr, Al, Ga, Be, Ti, and the majority of rare-earth elements), some heavy metals (Zn, Ag, Cd, and Co), and W.
