摘要：

A new spherical macroporous epoxy-melamine chelating resin was synthesized simply and rapidly and used for the preconcentrating and separation of trace of Ga(III), In(III),Bi(III), Sn(IV)and Ti(IV) ions from sample solutions. The ions analyzed can be quantitatively enriched by the resin at a flow-rate of 2ml/min at pH4,and quantitatively desorbed with 10ml of 2mol/L HCl+0.2gCS(NH2)2 at a flow-rate of 1ml/min with recoveries of over 97%,The chelating resin can be reused 7times without obvious loss of efficiency.
