摘　　要：A complex additive has been synthesized from maleic acid, sodium hypophosphite and Zn 2+ dodecyl-polyglucoside. It was used to prepare α-FeOOH by alkaline method with different concentration of additive oxidation of Fe 2+ has been discussed. The result showed that particle pattern of α-FeOOH was better when additive concentration was 1 0×10 -3 g/L. The γ-Fe 2O 3 powder with perfect comprehensive quality was prepared from α-FeOOH by dehydration, roast, reduction and oxidation.A complex additive has been synthesized from maleic acid, sodium hypophosphite and Zn 2+ dodecyl-polyglucoside.
