Abstract

The present invention relates to a kind of preparation method of the adsorption material of halloysite nanotube bonded with feather fiber, the method comprises the following steps: (1) prepare the feather fiber of surface modification: dissolve surfactant, reducing agent in distilled water, add clean Feather fiber, after shaking in a heating bath for 30 minutes, add an absolute ethanol solution in which a modifier is dissolved, shake and rinse to obtain a surface-modified feather fiber; (2) Halloysite bonded to the surface of the feather fiber: After the halloysite nanotubes are ultrasonically dispersed in distilled water, the surface-modified feather fibers are added, the reaction is shaken in a heating bath, cooled to room temperature, washed and dried, and the feather fibers with surface-bonded halloysite nanotubes are obtained. The method of the invention is simple, the production cost is low, and the obtained feather fiber bonded halloysite adsorption material has the characteristics of cheapness, non-toxicity, and environmental friendliness, etc., which not only broadens the application of feather fiber in the industrial and medical fields, but also improves the waste natural high The utilization value of molecular materials.

Description

technical field [0001] The invention relates to the field of natural polymer materials and the field of water treatment, in particular to a preparation method of a halloysite nanotube adsorption material bonded with feather fibers. Background technique [0002] Among various pollutants, dye wastewater is considered to be one of the most difficult pollutants to deal with. In textile, printing, paper making, cosmetics, food processing and other industries, the discharge of dye wastewater is particularly serious. Due to the high content of organic matter, high toxicity and refractory degradation, dye wastewater can cause many diseases, such as cancer, anemia and respiratory disorders. At present, the treatment methods of dye wastewater include adsorption method, biological oxidation method, electrochemical method, photocatalytic method and so on. Among them, the adsorption method has attracted much attention because of its low energy consumption and easy operation. Therefore,...
