Title (EN) HOLOCELLULOSE AEROGEL AND HEAVY METAL ADSORBENT USING SAME
(FR) AÉROGEL HOLOCELLULOSIQUE ET ADSORBANT DE MÉTAUX LOURDS L'UTILISANT
(KO) 홀로셀룰로오스 에어로겔 및 이를 이용한 중금속 흡착제
Abstract: front page image
(EN)A bead type holocellulose aerogel, which is prepared by a method of preparing a hollocellulose aerogel by dissolving holocellulose in an aqueous alkali-urea solution, has excellent heavy metal adsorption ability, and thus can be easily used as a heavy metal adsorbent for removing harmful heavy metal materials.
(FR)Cette invention concerne un aérogel holocellulosique de type bille, qui est préparé par un procédé de préparation d'aérogel holocellulosique par dissolution de l'holocellulose dans une solution alcali-urée aqueuse. L'aérogel holocellulosique selon l'invention possède une excellente capacité d'adsorption des métaux lourds, et peut par conséquent être facilement utilisé comme adsorbant de métaux lourds pour éliminer les matériaux de métaux lourds nocifs.
(KO)본 발명의 홀로셀룰로오스를 알카리-요소 수용액으로 용해시켜 홀로셀룰로오스 에어로겔을 제조하는 방법으로 제조한 비드형 홀로셀룰로오스 에어로겔은 중금속 흡착능이 우수하므로, 이를 유해 중금속 물질을 제거하기 위한 중금속 흡착제로 용이하게 이용할 수 있다.
