- Abstract
The present study reports a benign approach to prepare citrate capped iron particles using juice of a lemon fruit. Resultant particles were subjected to detailed adsorption studies for removal of arsenite aqueous solution of defined concentration. The planer reflection of XRD analysis suggested that iron particles were crystalline in nature. FT-IR study suggested that functional groups like -NH2, -NO2, -CO, and --CS were involved in arsenite ion sorption. The composite removal efficiency for As (III) was found to be 88.58%, at pH 4.5, with contact time of 30 min and temperature at 30°C. Data of adsorption were analyzed using various parameter like isotherm models, thermodynamic and kinetic models. Chemisorptions resulted in to formation of monolayer arsenite ions over the surface of prepared iron particles with maximum adsorption capacity; 55.53 mg/gm. Adsorbent hold good promises to remove arsenic from contaminated water.
