Abstract

본 발명은 키틴(Chitin)질을 추출하는 방법에 관한 것이다. 좀더 구체적으로, 본 발명은 정수 침전지의 폐기물인 슬러지로부터 키틴질을 추출하는 방법에 관한 것이다. 본 발명의 추출방법은 정수 슬러지에 유기용매를 가하여 색소를 제거하는 공정 ; 전기에서 수득한 물질에 알카리를 가하여 얻은 잔류물을 과산화수소 수용액에 침지시켜 단백질을 제거하는 공정 ; 전기에서 수득한 물질에 산 수용액을 가하여 무기물을 제거하는 공정; 및, 전기에서 수득한 물질에 유기용매를 가하여 염을 제거하는 공정을 포함한다. 본 발명에 의하며, 폐기물인 정수 슬러기로부터 산업상 유용한 저분자량의 키틴질을 간단히 경제적으로 추출할 수 있는 동시에 환경오염 방지 면에서도 그 효과가 크다.The present invention relates to a method for extracting chitin. More specifically, the present invention relates to a method for extracting chitin from sludge which is a waste of purified sedimentation basin. Extraction method of the present invention is a step of removing the pigment by adding an organic solvent to the purified sludge; A step of removing proteins by immersing the residue obtained by adding alkali to the material obtained in the foregoing in an aqueous hydrogen peroxide solution; Removing an inorganic substance by adding an aqueous acid solution to the material obtained in the former; And a step of removing the salt by adding an organic solvent to the material obtained in the foregoing. Industrial Applicability According to the present invention, it is possible to extract economically useful low molecular weight chitin from wastewater purified sludge, and the effect is also great in preventing environmental pollution.
