| titleOfInvention | Ferric arsenate powder |
| abstract | The present invention provides iron arsenate powder prepared from an arsenic containing solution with a very low elution concentration of arsenic. Iron arsenate powder is a powder of ferric arsenate, has a tetragonal crystal structure, and has lattice constants of a = 0.8950 to 0.8956 nm, b = 1.0321 to 1.0326 nm, and c = 1.0042 to 1.0050 nm at room temperature and normal pressure. The ferric arsenate powder is added with divalent iron ions to the arsenic-containing solution to make the molar ratio (Fe / As) of arsenic to iron in the solution to 1 or more, and heated to 70 ° C or more while reacting with an oxidizing agent, followed by reaction. It is obtained by solid-liquid separation and washing | cleaning solid content. |
