METHOD FOR MANUFACTURING CATION SORBING AGENT

摘要

PROBLEM TO BE SOLVED: To provide a method for continuously manufacturing a large amount of a Prussian blue-containing sorbent rich in the sorbing properties of a cation such as Cs or the like so as to provide the sorbent with desired solubility and dispersibility to water.SOLUTION: An iron ion-containing aqueous solution and a hexacyano iron ion-containing aqueous solution are introduced into a flow channel to be met and reacted with each other in a flowing process to form Prussian blue fine particles to thereby manufacture a cation sorbent containing the Prussian blue fine particles. In this case, the supply amount of iron ions and the supply amount of the hexacyano iron ions are adjusted to provide the Prussian blue fine particles with desired solubility and dispersibility to water.
