Abstract (in english)
   Sediments and soils have a high capacity for binding heavy metals from contaminated waters. However, these sediments become a potential source of water contamination by subsequently releasing the metals into the water when environmental conditions change. Samples of typical sediments from the Vienna Basin were collected for the experimental study of Cu, Cd, Zn, and Hg release from sediments to water. These sediments were characterized using chemical analysis, XRD analysis, the measurement of sediment sorption parameters, grain and pore analysis, and sequential analysis. Initially, a set of sediment samples was placed into batch reactors, each containing 0.1Msolution of CuSO4, CdSO4, ZnSO4, or HgCl2, and kept there for two months. These artificially contaminated sediments were subsequently leached by distilled water in flow-through reactors.
