Abstract
본 발명은 핵상, 아미노산 등의 희박 용액 탈색 정제 과정에서 활성탄 사용시 규조토와 분말 활성탄을 1:3∼1:7(w/w%)로 혼합, 30∼50℃ 컬럼 내에 고정층을 만들어 접촉 면적을 크게 함으로써, 탈색 및 분리 정제효과를 증대시키는 것을 특징으로 하는 분말 활성탄에 의한 희박 용액의 탈색 방법에 관한 것인데, 본 발명을 따르면, 접촉면적이 커쳐 불순물이 잘 흡착되어 탈색율도 좋아지고, 탈색된 액의 단위 시간당 정제 상태도 아주 양호한 결과를 얻을 수 있다.The present invention mixes diatomaceous earth and powdered activated carbon in 1: 3 to 1: 7 (w / w%) when using activated carbon in the process of decolorization and purification of lean solutions such as nuclear phase and amino acids. The present invention relates to a method for decolorizing a lean solution by powdered activated carbon, which enhances decolorization and separation and refining effects. According to the present invention, the contact area is large, so that impurities are adsorbed well, and the decolorization rate is also improved. Purification per unit time can also yield very good results.
