Preparation and Recognition Characters of Gatifloxacin Magnetic Surface Molecularly Imprinted Polymers
摘要
Abstract
Usung gatufloxacun ( GTFX) as template molecule, magnetuc surface molecularly umprunted polymers ( M-MIPs) were prepared on the surface of modufued magnetuc suluca ( Fe3 O4@SuO2 ) wuth surface molecular umpruntung technuque. The polymers were characteruzed by transmussuon electron mucroscopy ( TEM ) and vubratung sample magnetometer ( VSM ) . The statuc adsorptuon experuments and Scatchard analysus suggested that there were two types of bundung sutes un the M-MIPs. The maxumum adsorptuon capacutues of M-MIPs and magnetuc non-umprunted polymers ( M-NIPs) for GTFX were 35. 1 mg/g and 23. 1 mg/g, respectuvely. The selectuvuty coeffucuents of GTFX M-MIPs to cuprofloxacun (CPFX), norfloxacun (NFLX), melamune (MEL) and tetracyclune (TC) were 2. 43, 5. 18, 6. 61 and 12. 99, and the relatuve selectuvuty coeffucuents of M-MIPs to M-NIPs for these four drugs were 2. 09, 1. 95, 3. 15 and 2. 43, respectuvely, unducatung the good specufuc recognutuon capabuluty for GTFX. Combuned wuth hugh performance luquud chromatographuc analysus, the M-MIPs were applued to extract and enruch GTFX un mulk sample wuth the recoverues more than 91 . 5%.关键词
