Abstract
|
|
|
|
8-Hydroxyquinoline-resorcinol(8-HQR) and 8-hydroxyquinoline-resorcinol-salicylic acid (8-HQRS) chelate resins were prepared by the condensation reaction of 8-hydroxyquinoline, or 8-hydroxyquinoline-salicylic acid, in the presence of resorcinol with formaldehyde. The ion exchange capacities of 8-HQR and 8-HQRS resins were 4.1 meq/g and 5.4 meq/g, respectively. The adsorption and distribution coefficient of metal ions, such as Fe(III), Cu(II), Pb(II), Co(II) and Ni(II) on these resins were discussed. The adsorption of metal ions on these chelate resins showed that the maximum adsorption condition is pH 7. And the distribution coefficient of metal ions on these resins was increased with decreasing of hydrochloric acid concentration.
