Abstract

A method for extracting cellulose of Artemisia desertorum comprises steps as follows: step 1, Artemisia desertorum is cleaned after impurities are removed; step 2, the cleaned Artemisia desertorum branches are dried, crushed and sieved, and Artemisia desertorum powder is obtained; step 3, the Artemisia desertorum powder is soaked in distilled water and decolored, and the ratio of a material to a liquid is 1:10; a product is dried for standby use; step 4, a nitric acid mixed solution with 95% ethanol as a solvent is added to the decolored Artemisia desertorum powder, the mass percentage of nitric acid is 10%-40%, and the mixture is subjected to reflux extraction at the temperature of 60-100 DEG C; step 5, an extract is cooled and subjected to suction filtration, a filter cake is washed to be neutral and dried, and the cellulose of the Artemisia desertorum is obtained. The extraction method is simple, a reagent is recyclable, pollution-free and environment-friendly, and the cellulose has high yield and good purity.

Description

technical field

[0001] The invention belongs to the field of cellulose extraction, and in particular relates to a method for extracting cellulose from Artemisia annua. Background technique

[0002] With the increasing shortage of oil and natural gas energy, and the pollution of the natural world and the harm to human health by the products of combustion are becoming more and more serious, plant fiber, as a green and renewable resource, is one of the important topics in the study of sustainable energy development in the 21st century. one. Natural cellulose is the most abundant renewable resource in nature, inexhaustible and inexhaustible. Traditional sources of available natural cellulose are mainly wood, cotton stalks, etc. However, the limited wood resources in my country are in stark contrast to the increasing social demand, and many wood resources need to be imported. Therefore, in recent decades, Chinese experts have begun to shift their attention to herbaceous plants ...
