Abstract: front page image
(EN)Disclosed is a boron removal method which can remove boron from a boron-containing aqueous solution satisfactorily by using a small quantity of a chemical agent, and which hardly produces any precipitate. Also disclosed is a boron-removing agent which is easy to handle and has excellent boron-adsorption ability. A xorogel of an organic polymeric compound having a cis-type diol structure and a water-soluble salt of an alkali earth metal are added to a boron-containing water under alkaline conditions.
(FR)L'invention concerne un procédé de retrait du bore qui peut retirer le bore d'une solution aqueuse contenant du bore de façon satisfaisante à l'aide d'une petite quantité d'un agent chimique, et qui ne produit presque pas de précipité. L'invention concerne également un agent de retrait du bore qui est facile à manipuler et qui a une excellente aptitude à l'absorption du bore. Un xérogel d'un composé polymère organique ayant une structure diol de type cis et un sel soluble dans l'eau d'un métal alcalino-terreux sont ajoutés à une eau contenant du bore dans des conditions alcalines.
(JA) 少ない薬剤の使用量で、ホウ素含有水溶液中からホウ素を十分に除去することができ、沈殿物の生成量が少ないホウ素除去方法、及び取扱の容易性に優れ、ホウ素吸着能に優れたホウ素除去剤を提供する。cis型のジオール構造を有する有機高分子化合物の乾膠体と、水溶性アルカリ土類金属塩を、アルカリ条件下、ホウ素含有水に添加する。
