In the present study, the interactions of Bamboo Dust and its modified forms are investigated as adsorbents for the removal of Ffrom aqueous solution. A series of experiments were undertaken in a thermostat water bath batch agitator to assess the effect of different experimental variables such as solution pH, Fconcentration, time and amount of the adsorbents. The adsorption was dependent on the pH of the solution with Fremoval efficiency increased from pH 6.0 to pH 7.0, after which the trend slowly decreases. The adsorption process follows both Freundlich and Langmuir isotherm. The monolayer adsorption capacity obtained from the Langmuir equation increased from 8.01 mg/g for untreated adsorbents to 25.00 mg/g for acid-activated adsorbents. The kinetics of the adsorption was also studied for both first and second-order systems and were found to follow first-order kinetics.
