Analytical Letters, 21(2), 297-309.0003-2719https://hdl.handle.net/20.500.12395/16064Ion-exchange and ligand-exchange chromatography with the modified sporopollenin is a useful technique for the rapid separation of nucleosides, nucleotides, amino acids, amines and transit ion el emen ts . The sporopollenin has been modified for use as anion-, cation- and ligand-exchanger; diaminosporopollenin being the anion- exchanger form, sulphonated sporopollenin the cationexchanger form and carboxylated sporopollenin the ligand exchanger form. Sporopollenin was aminated by the trcatment with 1,: diruiiinothane for separation of nucleotides by anion-exchange; treatment with chlorosulphonic acid gave sulphonated sporopollenin for separation of amino acids by cation-exchange and treatment with brornoacetic acid gave carboxylated diaminosporopollenin for separation of nucleotides, nucleosides, amines and transition elements.eninfo:eu-repo/semantics/openAccessArticle212297309WOS:A1988M728200011N/A
