Sorption of Heavy Metals by Sediments in Soakaways

Sorption behavior of heavy metal species by soakaway sediment receiving urban road runoff from residential and heavily trafficked areas

“…The stable complexes were determined from the difference between the total dissolved and free ion and labile complex fractions of heavy metals. The pH, DOC, and heavy metal concentrations in HRD1, SED + HRD1 and SED + DW were reported by Murakami et al [30], and Fujita et al [34].…”

“…Ni, Cu and Zn were targeted because they were derived from traffic activities [33]. We previously used the samples of the soakaway sediment and the heavily trafficked road dust #1 for the sorption tests [30,34]. The heavy metal contents and the ignition loss were reported by Murakami et al [30,33] and Fujita et al [34].…”

“…d Heavy metal contents and ignition loss are given in [30,33,34]. 10 L/kg dry material and shaken for 16 h at a speed of 200 rpm at room temperature in the dark.…”
