Phosphorous recovery study from anodized waste phosphoric acid
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.
