の含水ゲルよりも劣っているなどの難点があった。(b) Conventional technology Traditionally, as adsorbents for uranium, there have been inorganic adsorbents such as hydrous titanic acid, and organic adsorbents such as chelate resins (amidoxime type, etc.); Since the substance is originally fine particles, it must be molded and granulated when used as an adsorbent, and this molding and granulation operation reduces the adsorption rate and weakens the mechanical strength of the granulated product. There was a drawback. On the other hand, organic adsorbents such as chelate resins have relatively high adsorption capacity, but their adsorption speed is slow and these adsorbents are extremely expensive, so they have drawbacks such as high recovery costs for the target metal. there were. On the other hand, inorganic materials such as porous glass are available as adsorbents for iron-containing organic substances such as hemoglobin and organic acid iron, but these materials are expensive and their adsorption performance is inferior to that of the hydrogel of the present invention. There were some difficulties, such as:

It has a convenient adsorption capacity,
The purpose of this invention is to obtain an adsorbent by an inexpensive and simple manufacturing method, and to use the adsorbent to recover nuclear fuel elements and iron-containing organic substances.

せると、このＩＲ吸収線は消失する。(d) Measures to solve the problem Kakishibu is usually available in liquid or powder form, but since it is extremely soluble in water, it cannot be used as an adsorbent for nuclear fuel elements such as uranium in this form. . Therefore, as shown in the examples, persimmon juice can be mixed with an aqueous solution of an aldehyde such as glutaraldehyde, glyoxal, formaldehyde, acetaldehyde, or salicylaldehyde, or sulfuric acid,
A new water-insoluble hydrogel composition was obtained by reacting with an aqueous solution of an acid such as phosphoric acid, acetic acid, or propionic acid. The specific gravity of the obtained composition (Example 1) was 1.08, and the IR spectrum was as shown in FIGS. 1 and 2.
3350.1350.1 due to phenolic OH group
Absorption near 220.770-740 cm' is observed. Further, the IR spectra of the gel composition obtained with persimmon tannin and an aldehyde aqueous solution and the gel composition obtained with persimmon tannin and a sulfuric acid aqueous solution both show similar patterns. On the other hand, when uranium is adsorbed to a hydrogel composition consisting of persimmon juice, aldehyde, and water, an absorption line due to o=u=o is observed near 910 cm'' (Figure 3). When the hydrogel composition is treated with dilute acid to desorb uranium, this IR absorption line disappears.

示すものと考えられる。(E) As shown in Functional Examples (1) to (5), the obtained persimmon astringent-based hydrogel composition exhibits an extremely excellent ability to adsorb nuclear fuel elements. For uranium, this material contains 1.
It can adsorb 71 g of uranium, and this uranium adsorption value is the highest of any uranium adsorbent published to date. The reason why this gel composition exhibits an extremely high adsorption capacity for nuclear fuel elements is that persimmon juice contains a significant amount of polyphenol compounds such as tannins and flavonols, and these compounds contain a large number of polyphenols. This is thought to be because the hydroxyl group forms a chelate compound with elements such as uranium. In addition, by gelling persimmon tannin, a 3D structure is created in which the polyphenolic hydroxyl group, which is an adsorption functional group, easily coordinates with nuclear fuel elements such as uranium, and this gel is an extremely hydrophilic substance.
This material is thought to exhibit extremely high ability to adsorb nuclear fuel elements such as uranium.
