Title
(EN) METHOD FOR PREPARING ORGANOSILICA HAVING FERROCYANIDE FIXED THERETO
(FR) PROCÉDÉ DE PRÉPARATION D'UNE ORGANOSILICE SUR LAQUELLE EST FIXÉ UN FERROCYANURE
(KO) 페로시안이 고정된 유기 실리카의 제조방법
Abstract
(EN) The present invention relates to a method for preparing an organosilica having a ferrocyanide fixed thereto, and more specifically, to a method for preparing a cesium-selective absorbent by combining a powder-type ferrocyanide to silica into which an ethylenediamine functional group is introduced. To this end, the present invention synthesizes the organosilica by using dodecylamine, which is a nonionic surfactant, tetraethylorthoslicate (TEOS), and [3-(2-aminoethylamino)propyl]-trimethoxysilane, and then combines the ferrocyanide to the ethylenediamine functional group.
(FR) Cette invention concerne un procédé de préparation d'une organosilice sur laquelle est fixé un ferrocyanure, et plus spécifiquement, un procédé de préparation d'un absorbant sélectif vis-à-vis du césium par combinaison d'un ferrocyanure de type pulvérulent à une silice dans laquelle un groupe fonctionnel éthylènediamine est introduit. Pour ce faire, la présente invention synthétise l'organosilice à l'aide de dodécylamine, qui est un tensioactif non ionique, de tétraéthylorthosilicate (TEOS), et de [3-(2-aminoéthylamino)propyl]triméthoxysilane, puis combine le ferrocyanure au groupe fonctionnel éthylènediamine.
(KO) 본 발명은 페로시안이 고정된 유기 실리카의 제조방법에 관한 것으로, 보다 상세하게는 파우더 형태의 페로시안을 에틸렌디아민 기능기가 도입된 실리카에 결합하여 세슘에 대한 선택성을 가지는 흡착제를 제조하는 방법에 관한 것이다. 상기 목적을 달성하기 위해 본 발명은 비이온 계면활성제인 도데실아민(dodecylamine)과 테트라에틸오르소실리케이트(tetraethylorthoslicate, TEOS), [3-(2-아미노에틸아미노)프로필]-트리메소시실란([3-(2-aminoethylamino)propyl]-trimethoxysilane, AAPTMS)을 이용하여 유기 실리카를 합성한 다음, 에틸렌디아민기능기에 페로시안을 결합하는 것을 특징으로 한다.
