Anodized Waste Phosphoric Acid was studied and reacted with hydroxyferroic oxide,which recovery phosphorous and synthetize iron phosphate,the optimal production conditions were determined with some single-factor-optimization-experiments.The results show that anodized waste phosphoric acid was diluted to a mass concentration of 8.00%phosphoric acid,the addictive amount of hydroxyferroic oxide was followed with that the mole ration of phosphorus and ferrum is 1.0∶1.1,the reaction temperature was 95 ℃,and the reaction time was 2 h,the recovery efficiency of phosphoric acid reached to 95.99%,the recovered iron phosphate can be used as a raw material for other high-value products.
