LIGAND-EXCHANGE CHROMATOGRAPHY OF AROMATIC-AMINES ON RESIN-BOUND COBALT ION

The use of cobalt metal for the selective separation of aromatic amine s is completed with a chemically bonded diamine and glyoxime functiona l groups onto Lycopodium clavatum, Grimes and amines are excellent com plexing agents for transition metal ions. Cobalt(II) metal ions can ea sily be immobilized on bis-diaminoethyl-glyoximated sporopollenin (bDA EG-sporopollenin). The ligand-exchange behavior of modified Lycopodium clavatum with respect to aromatic amines was investigated. This will permit the evaluation of bDAEG-sporopollenin ligand exchangers for the ir utilization as sorbents in the recovery, pollution control, and eli mination of amines from wastewater.
