    • Disclosed is a boron adsorbent having an excellent adsorbing ability against boron contained in a solution, which is inexpensive and has haigh general versatility. Also disclosed is a boron removal method which can remove boron efficiently in a simple manner. An amide derivative represented by the general formula (1) is added to a boron-containing water under alkaline conditions to cause the adsorption of boron to the amide derivative. Then, a cation source having two or more valencies is added to the water to cause the aggregation of the amide body. The aggregated amide body is removed from the water. In the general formula (1), m represens 1 or 2; X represents -CH 2 OH, -CHO or -COOH; n represents an integer of 2 to 5; X are independent from each other and n are independent from each other when m represents 2; and Y represents a monovalent hydrocarbon group having 6 to 16 carbon atoms when m is 1, and represents a divalent hydrocarbon group having 8 to 18 carbon atoms when m is 2.
    • 本发明公开了一种对溶液中所含的硼具有优异的吸附能力的硼吸附剂,其价格便宜且通用性高。 还公开了能够以简单的方式有效地去除硼的硼去除方法。 在碱性条件下将通式(1)表示的酰胺衍生物加到含硼水中,使硼吸附到酰胺衍生物上。 然后,将具有两个或更多化合价的阳离子源添加到水中以引起酰胺体的聚集。 聚集的酰胺体从水中去除。 在通式(1)中,m表示1或2; X代表-CH 2 OH,-CHO或-COOH; n表示2至5的整数; X彼此独立,当m代表2时,n彼此独立; Y表示m为1时的碳原子数为6〜16的一价烃基,m为2时表示碳原子数为8〜18的二价烃基。
