The Research on the Extraction Ability of Thiacalix[4]arene to Pb～(2+) and Cu～(2+) Ions

Extraction method detailed study the thiacalix [4] arene at different pH , extractant concentration and mixed systems of different lead , copper ratio of Pb ^{2 Cu ion extraction role . For the study thiacalix [4] aromatics extraction of heavy metal ions extraction mechanism and mode of action of the law , and development of new drugs used in the Excretion drive copper provides a theoretical basis .}
