The aim of this present study is targeted to decide the fluoride removal capacity of Aluminium modified bentonite (Al-bent) clay as well asbentonite (bent) clay material. The bentonite clay was collected and dried in an oven at 1200C for 24hrs. The Al-Bent clay was prepared by 300ml of 10% solution of Al2SO4.18H2O was mixed with 500 gram of bentonite clay and dried in an oven at 120&
