摘要: The extractability of Cd, Co, Cr, Ni and Pb was evaluated using ammonium chloride, calcium strontium chloride DTPA extractants in this research. eight surface soils were used to assess plant available metals with different extraction methods. amounts metal extracted related pseudototal contents, determined aer microwave digestion HNO 3 . Quantification dissolved by ICP-MS matrix-matched stan - dards. obtained results indicated a high variability depending on procedure, source pollution, nature the soil. showed that for calcareous best DTPA. In comparison salts, higher efficiency these found.
