Removal of boron dissolved in water

Abstract

The study aimed to investigate boron adsorption on activated carbon, activated carbon impregnated with different substances, activated alumina, zirconium dioxide and silica-aerosil. The removal of boron from water was carried out in static and dynamic systems. Isotherms for boron adsorption from model aqueous solutions on various adsorbents were applied and Langmuir constants were calculated. The results indicate that the application of the impregnants increases the ability of activated carbon to adsorb boron. The first removal of boron using activated carbon impregnated with mannitol compared favorably with other impregnants. © 2007 American Institute of Chemical Engineers.
