Sorbția antibioticelor din mediu apos pe sorbenți naturali și sintetici [Articol]

Abstract

There has been studied the adsorption of ofloxacin from aqueous solution on natural tripol from the Sănătăuca deposit, Republic of Moldova. There has been determined that in the range of pH values between pH = 1,0 and pH = 7,0 sorption reaches a maximum at pH = 3,0. There has been established that with the increase of the antibiotic concentration, its sorption increases. The constants from Langmuir and Freundlich adsorption isotherms have been determined. The ofloxacin shows a high affinity towards tripol, and the sorption process is more appropriately described by the Freundlich model.
