Manganese/oxygen compound with arsenic adsorption
Abstract:
A novel technique that is able to efficiently remove, in addition to pentavalent arsenic, trivalent arsenic that has been considered to be difficult to remove. By using a manganese oxygen compound which is characterized by being a product of burning or heating which comprises an oxygen compound of bismuth and an oxygen compound of manganese and by containing manganese as a major component, an aqueous arsenic solution is treated to adsorptively remove the arsenic.
