- Аннотация: Antibiotics, cyanotoxines, peptides have highly toxic effect on the environment. Currently, many studies are actively conducted on removal of antibiotics, including peptide antibiotics, and products of their biodegradation from water and waste water [1]. New adsorption techniques and new modern nanomaterials as adsorbents are using for this purpose [2]. In the study adsorption of antimicrobial animal peptides (arenicin and tachyplesin) [3] and polymyxin antibiotics B and M from aqueous solutions was performed using the new carbon nanomaterial Taunit M is represented by multilayer packet nanotubes predominantly conical graphene layers whose surface was under functionalization by COOH groups (OOO "NanoTecentr" Russia, Tambov) [4]. It was shown that drugs effectively adsorbed on Taunit M due to formation of ionic bonds between positively charged NH3 + groups in the structure of antibiotics and the negatively charged COO - groups on the surface of the nanotubes.
