  • Carbon supported activated alumina absorbent useful for the removal of fluoride ions from water and a process for the preparation thereof
    Patent number: 8242051
    Abstract: The present invention provides a novel adsorbent carbon supported activated alumina (CSAA) which posses both the advantageous characteristics of carbon and alumina viz., the high specific surface area associated with activated carbon and high sorption capacity of alumina towards F? Carbon supported activated alumina has an added advantage of its usage in the neutral pH unlike alumina and alumina impregnated carbon which are found to be efficient only in acidic pH. It is more efficient compared to carbon in terms of its sorption capacity towards F? and is therefore useful for the efficient removal of fluoride ions from water.
