Title:
ANIONIC TREATMENT AGENT, METHOD OF PRODUCING ANIONIC TREATMENT AGENT, AND METHOD OF REGENERATING ANIONIC TREATMENT AGENT
Document Type and Number:
Japanese Patent JP2022161597
Kind Code:
A
Abstract:
To provide an anionic treatment agent that removes the disadvantages of an anionic treatment agent using a layered double hydroxide as a raw material and improves the anion exchange ability, and is suitable for inventory management.SOLUTION: An anionic treatment agent A is a product produced by mixing a layered double hydroxide 1 having anion exchange ability and a feldspar clay 2 that maintains its shape even in water by drying, and subjecting the mixture to the steps of rolling and granulating, drying, and classifying. The layered double hydroxide 1 includes a chlorine type, a carbonate type, or the like depending on the anion species contained in the layer, and when an anionic treatment of an ionic fluorine, nitrogen, or phosphorus compound is intended, it is desirable to use a chlorine type layered double hydroxide having excellent anion exchange selectivity as a raw material. The feldspar clay 2 is obtained by grinding feldspar, which is a type of a tridimensional techtosilicate containing an aluminosilicate such as an alkali metal or an alkaline earth metal as a main component, to form a powder having a size of 5 μm or less.SELECTED DRAWING: Figure 1
