Chemical Speciation of Zn, Cd, Cu, and Pb in Pore

Knowledge of trace metal speciation in soil pore waters is important in addressing metal bioavailability and risk assessment of contaminated soils. Numerous analytical methods have been utilized for determining trace metal speciation in aqueous environmental matrixes; however, most of these methods suffer from significant interferences. The Donnan dialysis membrane technique minimizes these

Environmental contamination of Zn, Cd, Ni, Cu, Eleven surface soil samples from calcareous soils of industrial areas in Hamadan Province, western Iran were analyzed for total concentrations of Zn, Cd, Ni, Cu and Pb and were sequentially extracted into six fractions to determine the bioavailability of various heavy metal forms. Total Zn, Cd, Ni, Cu and Pb concentrations of the contaminated soils were 658 (57–5,803), 125.8 (1.18–1,361 A Comparison of ICP-OES and UV-Vis Spectrophotometer for Zn >0.01 and ≤0.1 213.856 [8] As a comparison, the HACH DR5000 UV-Vis Spectrophotometer [16] (Hach, Colorado, USA) was also used for detection of heavy metals such as Cd, Cr, Co, Cu, Fe, Pb, Mn, Ni and Zn in wastewater and soil samples. The specifications of HACH DR5000 UV Vis Spectrophotometer

Phytoextraction of Cu, Zn, and Pb Enhanced by Phytoextraction is a green remediation technology for clean-up contaminated soils. The effect of chelator application including EDTA, EDDS, and citric acid on phytoextraction of Cu, Zn, and Pb into high biomass vetiver ( Vetiveria zizaniodides ) was investigated in the hydroponic experiment and the pot experiment. In the hydroponic test, EDTA induced the most significant toxic symptom on
