The Research On The Extraction Ability Of Thiacalix[4]arene To Pb～(2+) And Cu～(2+) Ions

The extraction of thiacalix[4]arene to lead ion and copper ion was investigated and discussed in this paper, considering the influence of PH, extrant concentration and molar ratio of the two ions. The results turned out essential at explaining the mechanism and the function mode of the thiacalix[4]arene extraction.to heavy metal ion, and will theoretically support the developing of new medicine to get rid of Pb²⁺ and Cu²⁺ ions from human body.
