9/11/2015· Mean concentrations (mg/kg dw) of heavy metals in the communities decreased in order of Zn (39) ˃ Cr (21) ˃ Pb () ˃ Cu () ˃ As () ˃ Ni () ˃ Co () ˃ Hg () ˃ Cd (). Correlations among heavy metals and soil properties indicated that soil organic matter could have substantial influence on the total contents of these

We applied geochemical (ICPMS, WDXRF, GFAAS, and AMA 254) and mineralogical (EPMA) studies of 137 samples to ore mineralization from MiddleTriassic sedimenthosted ZnPb (Mississippi Valleytype MVT) and Lower Zechstein sedimenthosted stratiform (SSC) CuAg (Kupferschiefertype) deposits in Poland. They contain a number of trace elements which are not recovered during the ore processing.

In a field experiment we investigated the efficiency of two hyperaccumulating species, four agricultural crop plants, and one woody crop, at phytoextraction of Zn, Cd, and Cu from a polluted calcareous soil. In addition, we examined the possibility to enhance the phytoextraction of these metals by application of nitrilotriacetate (NTA) and elemental sulfur (S8) to the soil.

The objective of this study is to immobilize Pb, Cu, and Zn in a multimetal contaminated soil using triple superphosphate fertilizer (TSP) and phosphate rock tailing (PR) materials, alone and in combination. The treatment effectiveness was evaluated with a column leaching experiment under simulated rainfall conditions. More than 90% of Pb and Cu were stabilized in the upper layer soil (010cm

This study presents the pH performance of six selected IX resins in extracting Cu 2+, Fe 2+, Pb 2+ and Zn 2+ from acetic, lactic and citric acid media simulated weak acid leachate. Acetic acid media displayed limited suppression of metal extraction, whilst lactic and citric acid media rendered MTS9100 ineffective.
