Uranium(VI) can be quantitatively precipitated from aqueous solution in the pH range 2.1-6.9 with pyridine-2,6-dicarboxylic acid in the presence of tetraphenylarsonium chloride. This provides a new rapid gravimetric method for uranyl ion as an organic chelate complex of high molecular weight. Sodium, aluminium, copper and nickel as well as nitrate, chloride… CONTINUE READING
