| Description | In some areas of developing countries, health effects have been feared because underground water contaminated with arsenic has been used as drinking water. Therefore it is desired that effective and inexpensive 'arsenic removal agents' should be developed and provided to reduced health risk. To develop the arsenic removal agents (arsenic adsorbents or flocculants), systematic experiments that focused on the components related closely to arsenic removal need to be carried out and also the fundamental data that obtained in the experiments need to be stored and organized. In this study, magnesium was focused as one of the components effective for arsenic removal. Arsenic removal tests were carried out using artificial arsenic contaminated water. Six types of magnesium salts (magnesium chloride, magnesium sulfate, magnesium oxide, magnesium hydroxide, magnesium carbonate (light) and magnesium carbonate (heavy)) were tested and arsenic removal performance was evaluated for each kind of magnesium salt. Magnesium chloride and magnesium sulfate could not remove arsenic at all. On the other hand, magnesium oxide, magnesium hydroxide and two magnesium carbonates (light and heavy) removed arsenic effectively. The arsenic adsorption behaviors on these four types of magnesium salts were represented approximately by Freundlich adsorption isotherm. | |||||||||||||||
