The influences of the oxidant( [Math Processing Error] ) on the FeOOH formation were studied with fixed [Math Processing Error] concentration (0.5M) and NaOH equivalent ratio(0.5). The characteristics of the synthesized powders were evaluateed by XRD, and equantitative phase analysis. [Math Processing Error] (Geothite) and/or [Math Processing Error] was promoted when [Math Processing Error] was used as a oxidant which is stronger oxidizing agent than [Math Processing Error] .

Keywords:ferrous sulfate;ozone oxidation
