To assess the mobilities of Pb, Cd, and Zn from a contaminated soil, the effects of redox potential and pH value on metal solubilities were investigated. Both redox potential and pH were found to greatly affect heavy metal solubility in the soil. Results showed that the soil suspension under continuous oxygen aeration for 21 days resulted in increases of redox potential from 290 to 440 mV and pH value from 6.9 to 7.0, respectively. Soluble concentrations of Pb, Cd, and Zn varied with time, and… Expand
Effects of redox potential and pH value on the release of rare earth elements from soil.
TLDR
It was found that alteration of pH value and redox potential might affect the change of La, Ce, Gd and Y species in the soil as well as the influence ofredox potential on Ce was more remarkable than on La, GD and Y. Expand
Effects of incubation on solubility and mobility of trace metals in two contaminated soils.
TLDR
Changes in concentrations of Fe(II), Pb, Cu and As in pore water with incubation time were similar to those in leachate, i.e. water soluble metals were positively related to exchangeable metals in the two contaminated soils. Expand
Trace Element Solubility in a Multimetal-Contaminated Soil as Affected by Redox Conditions
Redox conditions play an outstanding role in controlling the behaviour of trace elements in soil environments. They are not only sensitive to water saturation but also to soil temperature becauseExpand

Mobilization of heavy metals from urban contaminated soils under water inundation conditions.
TLDR
The results show that reductive dissolution of iron and manganese compounds was markedly enhanced by organic matter, however, mobilization of Fe and Mn was affected by the abundance of these metals in the soils. Expand

Effect of experimentally induced reducing conditions on the mobility of arsenic from a mining soil.
TLDR
The ability of two chemical reducing agents, sodium ascorbate and sodium borohydride, to produce different redox environments in a gold mining soil contaminated with arsenic was investigated and a method for estimating the release of contaminants from contaminated sites under reducing conditions is proposed.
