Separation of amines by ligand exchange. Part IV ligand exchange with chelating resins and cellulosic exchangers

Abstract

Chelating, sulfonic and cellulosic exchangers were compared in ligand exchange chromatography. Chelating resins retain metal ions the best, but have a low ligand binding capacity. Cellulosic exchangers show excessive metal leakage. Sulfonated polystyrene resins loaded with nickel ions give best results in most cases. Data are presented on ligand exchange chromatography of simple aliphatic amines, hydrazine and substituted hydrazines, purine and pyrimidine bases. © 1967.
