Use of newly synthesized guar based chelating ion exchange resinin chromatographic separation of copper from nickel ions

摘要

Crosslinked guar functionalized with β-amino-a-methylphenethyl alcohol (AMPA) is found to be very efficient forseparation of copper from nickel ions in a mixture using column chromatography. The IR spectra of the resin and thenitrogen content data support the successful incorporation of chelating agent in the guar matrix. The moisture content,bulk density, bulk volume and ion exchange capacity were determined by standard methods. Distribution coefficientdata, determined at various pH for both metal ions, reveal an effective separation of Cu(II) from Ni(II) ions using thenewly synthesized guar epoxy ether ofβ-amino-a-methylphenethyl alcohol (GEE-AMPA)
