Biological bamboo cellulose extraction method

Abstract

The invention relates to a biological bamboo cellulose extraction method, and belongs to the field of biotechnology and cellulose extraction. The biological bamboo cellulose extraction method comprises following steps: reparing a cellulose extracting agent from water, sodium bicarbonate, ammonium tartrate, lauryl alcohol polyoxyethylene ether, calcium chloride, ammonia water, hydrogen peroxide, urea, lauryl sodium sulfate and polyoxyethylene sorbitan fatty acid ester-80; mixing a crude enzyme solution A and a crude enzyme solution B to obtain a mixed enzyme solution; removing leaves of moso bamboos, splitting, cleaning, cutting off, and boiling with water; crushing the treated moso bamboos to obtain moso bamboo powder; mixing and soaking the bamboo powder and the cellulose extracting agent, heating, carrying out solid-liquid separation, and collecting filter residues; adding the filter residues into the mixed enzyme solution for soaking; and carrying out solid-liquid separation on thesoaked bamboo powder, collecting filter residues, cleaning the filter residues with deionized water, and carrying out high-temperature drying to obtain bamboo cellulose. The biological bamboo cellulose extraction method is simple and feasible, cellulose is extracted from moso bamboos by using a biological method, the impurity content is low, and high energy consumption and environmental pollutionare avoided.

Description

technical field [0001] The invention relates to a method for extracting biological bamboo cellulose, which belongs to the field of biotechnology and cellulose extraction. Background technique [0002] Forest resources and agricultural resources are the most important resources related to people's livelihood in our country, and they are of various types and varieties. Among them, bamboo resources are one of the most widely distributed resources. my country has more than 400 kinds of bamboo plants, accounting for one-third of the world's bamboo resources. The existing bamboo forest area is about 5.4 million hectares, accounting for 2.8% of the national forest area. At present, bamboo resources are mainly used in the processing of bamboo shoots, the production of bamboo woven products such as bamboo mats and blankets, the manufacture of bamboo charcoal materials and bamboo composite materials, and many other fields. Bamboo fiber is a kind of natural fiber directly extracted ...

Problems solved by technology

Chinese patent CN108660836A provides a method of extracting cellulose by using straw. In this method, the straw is crushed first and then mixed with lye, and then the mixed solution is subjected to steam explosion treatment, and finally chlorinated Pyridine aqueous solution is processed to obtain cellulose. The steam explosion method used in this method requires professional equipment, the production cost is high, and the use of sodium hydroxide and potassium hydroxide is easy to pollute the environment.

Chinese patent CN105507049A provides a method for extracting cellulose from mung bean skin. The method obtains cellulose through pretreatment, microwave-ultrasonic combined assisted alkali treatment, sodium hypochlorite decolorization and dry crushing. The method requires conditions and equipment High, narrow application range
