Synthesis, Characterization and Ion-Exchanging Properties of a Novel Ion-Exchange Resin, Part II

A polyamine (PA) was prepared by condensation of 1,4-bischloromethyl benzene and 1,2-thanediamine. This PA was then treated with cyanuric chloride at 0°C followed by reaction with 5-amino-8-hydroxyquinoline in THF in conc. NaOH (PH 9-10) at room temperature for 8 h. The resultant polymer, designated as polyamine-s-triazine-5-amino-8-hydroxyquinoline (PATHQ), was characterized by elemental analysis, IR spectral studies, and thermogravimetry. The PATHQ was monitored for its chelating and ion-exchanging properties. The polymeric metal chelates of PATHQ with Cu2+, Zn2+, Mn2+, Ni2+, and Co2+ metal ions were prepared and characterized by metal:ligand ratio, IR and reflectance studies, magnetic properties, thermogravimetry and microbicidal activity. The batch equilibration method has been adopted for evaluation of ion-exchange properties.
