Fractions and solubility of heavy metals cadmium cobalt chromium nickel and lead in soils


Fractions and solubility of heavy metals cadmium cobalt chromium nickel and lead in soils



Geoderma 16(1): 55-69



ISSN/ISBN: 0016-7061

A successive fractionation of heavy metals-Cd, Co, Cr, Cu, Ni and Pb-as water soluble, 0.01 N NH4Cl-exchangeable and 0.01 N NaOH-extractable was carried out, in order to determine their chemical forms in soils. Ionic activities of the heavy-metal compounds expected in equilibrium soil solutions were calculated and are presented in a solubility diagram as a function of pH. The ionic activities in soil solutions show an undersaturation with respect to heavy metal-oxide, carbonate, sulfate, chloride and phosphate compounds. The ionic activities of the elements studied are pH dependent; the correlation coefficient for pH vs pCd reaches a value 0.66 (significant at the 1% level. Significant correlations between ionic activities and NH4Cl-exchangeable fractions were found for Cd, Co, Ni and Pb with correlation coefficient values of 0.88, 0.89, 0.97 and 0.79, respectively. Desorption and adsorption phenomena are responsible for the regulation of heavy-metal behavior in soils. The NaOH-extractable fraction of the heavy metals does not show any relationship to the organic matter in the soils.
