Abstract

The invention discloses a glass fiber modified biomass adsorbent. The glass fiber modified biomass adsorbent is characterized by being prepared from the following raw materials in parts by weight: corn straw, peanut shell, formaldehyde, a sulfuric acid solution, glass fiber, quartz powder, manganese nitrate, copper sulfate, 3- (methacryloyloxy) propyltrimethoxysilane, sodium diethyldithiocarbamate, sodium silicate, sodium acetate, anhydrous ethanol, dimethyl terephthalate, 1,2-propanediol, pentaerythritol, tetraisopropyl titanate, 2,2-dihydroxymethylpropionic acid, acetone, methanol and a proper amount of deionized water. The glass fiber modified biomass adsorbent has the characteristics of large particle size, low cost, environment friendliness, easy recycle and good adsorption.

Description

technical field [0001] The invention belongs to the technical field of adsorbents, and in particular relates to a glass fiber modified biomass adsorbent and a preparation method thereof. Background technique [0002] In recent years, the biological adsorption method using various natural biomass resources or derivatives as adsorbents has been developed rapidly. It is biodegradable and is an excellent green adsorption material. Biomass is used to adsorb metal ions in solution. On the one hand, due to its high porosity in physical structure and large specific surface area, it can physically adsorb with metal ions; on the other hand, biomass is mainly composed of cellulose. , hemicellulose, pectin, lignin, the structure of these components contains abundant functional groups, such as -COOH, -OH, -NH 2 etc., metal ions can be adsorbed by ion exchange, chelation, etc. [0003] In the article "Preparation and Adsorption Performance of Straw Biocarbonaceous Adsorbent" by Zhang J...
