Abstract
A new compound represented by a composition formula FeO(OH)((SO), (HPO))(a+b=x, 1≦x≦1.75, 0<a≦1.658, 0.092≦b≦x) formed by adding a shwertmannite of a composition formula FeO(OH)(SO)(1≦x≦1.75) to a phosphoric acid solution of a pH value of 2-9 thereby achieving a stabilization by an adsorption of phosphoric acid, shows a very firm stabilization under conditions of 0<a≦1.253 and 0.497≦b≦x. The new compound has a high stability, can maintain a high adsorbing ability for arsenic and the like and a cleaning level for a necessary period or semi-permanently, and can adsorb arsenic and the like in polluted water or polluted soil.
