Extraction by barium salts of heavy metals from two Chilean soils



Extraction by barium salts of heavy metals from two Chilean soils



Soil Science Society of America Journal 48(6): 1240-1243



Extraction of Cd, Cu, Ni, and Zn by BaCl2 and Ba(ClO4)2 solutions from El Recuerdo (Vertisol) and Puerto Octay (Andept) soils was used to measure the amounts of metals remaining extractable during a 60-d storage period under air-dry and wet conditions. The El Recuerdo soil with an original pH of 7.3 sorbed about twice the amounts of metals sorbed by the Puerto Octay soil with an original pH of 5.5.
