Abstract
n the present study As(V) was removed bycitrus paradisi (grape fruit) peel.Kinetics of the adsorption reaction was analyzed by the Pseudo second order and Morris-weber equations. Freundlich and Langmuir isotherm models were utilized for understanding of the relationship between the arsenic ions and citrus paradisipeel adsorbent. The maximum measured uptake capacity of citrus paradisiwas 37.76 mg.g-1 at pH 4. FT-IR characterization of unloaded and As(V)loaded citrus paradisipeel adsorbent showed the participation of carbonyl (CO) and hydroxyl (OH) groups in adsorption process. The proposed citrus paradisipeel adsorbent with optimized parameters was used for the removal of arsenic from arsenic contaminated real water samples.
