摘要: Abstract The sequential extraction test, known as a BCR procedure, was used to assess leachability of heavy metals (Zn, Cd, Pb, Cu) from the metallo-organic sorbent—iron humate—loaded with these metals. test allowed discriminate between various fractions metals, namely acid-extractable fraction, fraction bound Fe oxides, and organic matter. It proven that are mainly oxides matter, thus they may be relatively hardly liberated into environment. exhibited very good repeatability, when it applied loaded sorbent—relative standard deviations were typically lower than 10%.
