متن کاملEquilibrium, kinetics and breakthrough studies for adsorption of fluoride on activated alumina
Contamination of drinking water due to fluoride is a severe health hazard problem. Excess of fluoride (>1.5mg/l) in drinking water is harmful to the human health. Various treatment technologies for removing fluoride from groundwater have been investigated in the past. Present investigation aims to remove fluoride by activated alumina. Adsorption isotherm has been modeled by Langmuir equation an...
متن کاملStudy of Equilibrium Adsorption of Orthophosphate on Alumina Adsorbents
This work is a part of a comprehensive study on economic re-utilization of a phosphate contaminated industrial water stream in a typical petrochemical plant in the Kingdom of Saudi Arabia. The experimental study is primarily the adsorption of orthophosphate at equilibrium conditions on 28x48 mesh Alcan Alumina AA 400G. A fixed amount of orthophosphate solution containing 10 mg/L of phosphorus i...
