Abstract:
A sorbent material based on a hydrazone ligand, formaldehyde-2,4–dinitrophenylhydrazone was prepared by immobilizing the ligand into a silica sol-gel matrix. The capability of the sorbent material for the extraction of seven biogenic amines was investigated. Under the optimum condition, the sorbent material exhibited preferential selectivity towards the aliphatic (putrescine, PUT; cadaverine, CAD; spermidine, SPD) and the heterocyclic (histamine, HIS) over the aromatic (tryptamine, TRY; 2-phenylethylamine, PEA, tyramine, TYR) biogenic amines.
