Journal of the institution of engineers (India): Series ASummary: An eco-friendly, innocuous, inexpensive as well as effective treatment of fluoride-contaminated water has been an urgent need to resolve the water-related issues. So for the removal of fluoride, batch adsorption experiments were carried out to study the effect of pH (varied from 2 to 12), adsorbent dose (varied from 0.05 to 0.50 g/L) and initial fluoride concentration (varied from 5 to 20 mg/L) on saw dust adsorbent. The maximum removal of fluoride was found to be 88% at optimum conditions (pH 7, adsorbent dose 0.20 g/L and initial fluoride concentration 5 mg/L). Among the various kinetic models used, pseudo-second-order model best fitted the kinetic data and Langmuir isotherm was also best fitted. The maximum capacity of adsorption was found to be 16.5 mg/g.
