Abstract
A method for preparing nano iron phosphate with low sulfur content. The method may include: S: mixing a phosphorus source and an iron source to obtain a raw material solution, then adding alkali and a surfactant, adjusting a pH, and stirring and reacting to obtain an iron phosphate dihydrate slurry, S: adding phosphoric acid solution into the iron phosphate dihydrate slurry, adjusting the pH, heating and stirring for aging, and filtering to obtain iron phosphate dihydrate, S: adding water into the iron phosphate dihydrate for slurrying, and grinding to obtain a ground slurry; and S: adding the ground slurry into a washing solution to wash, carrying out solid-liquid separation, and calcining a solid phase to obtain the nano iron phosphate with low sulfur content.
