A SPINEL ALKALINE EARTH METAL FERITE IMPREGNATED ACTIVATED ALUMINA ADSORBENT FOR EFECTIVE DEFLUORIDATION OF WATER AND A PROCESS FOR THE PREPARATION THEREOF

摘要

The present invention relates to a spinel magnesium ferrite impregnated activated alumina adsorbent for effective defluoridation of water and a process for the preparation thereof. The invention provides a newly modified activated alumina (spinel magnesium ferrite impregnated activated alumina) to improve the defluoridation capacity 2: 2 times. The invention provides a spinel ferrite composition which can be prepared .from their cost effective and less toxic precursors for impregnation purpose.
