Latest Patents
Xueliu Xu holds a patent for a method titled "Method for regulating particle size of Prussian white." This method involves a series of steps to control the particle size of Prussian white through precise chemical reactions. The process includes adding a food-grade manganese sulfate solution and a complexing agent to a sodium ferrocyanide solution, which initiates a precipitation reaction to form Prussian white crystal nuclei. Subsequently, the food-grade manganese sulfate solution is replaced with an industrial-grade manganese sulfate solution, allowing the crystal nuclei to grow into a slurry. The slurry undergoes aging, solid-liquid separation, washing, and drying to yield a Prussian white product with a specific particle size. The regulation of particle size is achieved by controlling the timing of the addition of the manganese sulfate solutions.
