摘要：NOVELTY - Preparing iron phosphate by precipitation reaction under normal temperature and mild pH conditions comprises (i) dissolving soluble iron salts in deionized water, stirring, adding oxalic acid, stirring and dissolving, (ii) adding iron, phosphorus into solution obtained in step (i), adding soluble phosphorus salt, adjusting pH with ammonia, flocculating, stirring, washing precipitate for 3 times with deionized water, filtering and drying to obtain iron orthophosphate precursor, and (iii) placing resulting iron orthophosphate precursor in a muffle furnace and then calcinating for a certain time. USE - The method is useful for preparing iron phosphate by precipitation reaction under normal temperature and mild pH conditions. ADVANTAGE - The iron phosphate: has high security; saves energy; and is suitable for industrial production and environmentally friendly. DETAILED DESCRIPTION - Preparing iron phosphate by precipitation reaction under normal temperature and mild pH conditions comprises (i) dissolving soluble iron salts in deionized water, stirring, adding oxalic acid, stirring and dissolving, (ii) adding iron, phosphorus into solution obtained in step (i), adding soluble phosphorus salt, adjusting pH with ammonia, flocculating, stirring, washing precipitate for 3 times with deionized water, filtering and drying to obtain iron orthophosphate precursor, and (iii) placing resulting iron orthophosphate precursor in a muffle furnace and then calcinating for a certain time to obtain final product.
