Using Sorbents modified by gold nanoparticles in chromatography

Resumo

The use of sorbents modified by metal nanoparticles in HPLC for the separation of various organic substances is discussed. Authors’ data on the synthesis and study of silicas modified by gold nanoparticles stabilized by organic ligands are summarized. A possibility of the successful separation of nitroaniline, aminopyridine, hydrazines, water-soluble vitamins, β-blockers, and their enantiomers on the synthesized sorbents is shown.
