Abstract

This study investigated the performance of sorghum and canola as cheap natural adsorbents in fluoride (F) removal from water. The natural materials were dried, crushed, screened, and bicarbonate-treated. The effect on adsorbent performance of various parameters, such as pH, adsorbent dose, contact time, and F concentration, were investigated. The F concentration was measured by spectrophotometer at λmax=570 nm. The isotherms and kinetics of adsorption were determined. The results indicated that F removal by both adsorbents increased with increasing contact time and adsorbent dose. However, the removal rate reached a constant amount with an 10 g/L dose of canola and sorghum after 90 and 60 min respectively. For an initial F concentration of 10 mg F/L, the F removal efficiency by the activated stalks of sorghum and canola was 94% and 79%, respectively. Maximum F removal was obtained at pH=5. The adsorption data followed the type 2 Langmuir isotherm and the pseudo-second-order kinetic. The studied adsorbents can potentially be used as low-cost media for removal of F from, for example, industrial effluents. © 2015 The International Society for Fluoride Research Inc.
