Adsorption of Hydrogen Fluoride on Alumina
In the smelting of aluminium, HF fumes are produced that are subsequently trapped by absorption onto alumina. The factors that affect the adsorption capacity of alumina have been studied previously and are weU established, but the mechanism by which HF adsorbs onto the alumina surface is not well understood. In this study, x-ray photoelectron spectroscopy (XPS) was used to investigate the natur...
متن کاملRemoval of fluoride from drinking water by adsorption onto Activated Alumina and activated carbon
The ability of activated alumina and activated carbon to remove Fluoride from aqueous solution has been investigated. The studies were carried out as functions of contact time, concentration and pH. The data indicate that activated alumina surface sites are heterogeneous in nature and that fits into a heterogeneous site binding model. The optimum pH for complete removal of Fluoride from aqueous...
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 کاملCompetitive adsorption between fluoride and natural organic matter onto activated alumina
Natural organic matter (NOM) is a major water constituent that affects the performance of drinking water treatment processes and the quality of drinking water. Besides, several studies have shown that NOM can be adsorbed on the surface of oxides being thereby able to compete with other ions. The overall goal of this study was essentially to investigate the competitive adsorption between fluorid...
متن کاملFluoride Removal from Water by Adsorption on a High Alumina Content Bauxite
Drinking water contamination by fluoride is recognized as a major public health problem in many parts of the world. In fact, although fluoride is an essential trace element for animals and humans, excessive fluoride intake may cause adverse health effects. In this study we investigated the potential of a natural, high alumina content, bauxite for the removal of fluoride from contaminated water....
