Embodiment Construction

[0019] A preparation method for borax synergistically modified silica-modified lobster shell adsorption microspheres, comprising the following steps:

[0020] (1) Put 25 parts by weight of lobster shells in a high-pressure steam sterilizer, set the temperature at 125°C and keep it warm for 8 minutes, take it out and add 70 parts by weight of 0.3mol / L sodium hydroxide aqueous solution, soak it at 23°C for 18 hours, then clean it with water Wash 3 times, dry in the air, crush in a press, and set aside;

[0021] (2) Dissolve the product obtained in step (1) in 120 parts by weight of ethanol, add 6 parts by weight of silicon dioxide and mix evenly, slowly add 4 parts by weight of borax under stirring conditions, ultrasonically react for 1 hour, and suction filter after cooling. Wash with absolute ethanol three times, dry at 45°C for 18 hours, and set aside;

[0022] (3) Add 8 parts by weight of bentonite to the result of step (2), stir at low speed for 18 hours, then add 180 part...

Abstract

The invention discloses a preparation method of lobster shell adsorption microspheres modified by borax combined with silicon dioxide. The preparation method includes: subjecting lobster shell to high-temperature treatment in a high-pressure steam sterilizing pot; adding the lobster shell into a sodium hydroxide solution for soaking, squeezing and crushing; dissolving in alcohol, and adding silicon dioxide and borax for modification; adding bentonite, stirring for a long time, and adding alkali and epichlorohydrin for reaction; mixing with paraffin and emulsifier, dispersing, emulsifying, and shaping to obtain the lobster shell adsorption microspheres. The adsorption microspheres are simple in preparation process, capable of quickly capturing and adsorbing harmful substances, low in cost and high in stability and adsorption capacity.

Description

technical field [0001] The invention belongs to the technical field of adsorption microspheres, and in particular relates to a method for preparing adsorption microspheres of lobster shells modified by borax and silica. Background technique [0002] In recent years, my country's crayfish industry has developed rapidly. While satisfying the national material life, it also produces a large amount of waste represented by shrimp shells. Chitin is a natural polymer material obtained by acid-base processing of shrimp, crab or insect shells, and chitosan is a derivative of chitin. [0003] Chitin, also known as chitin, chitin, polyacetylglucosamine, etc., is a linear polymer formed by condensation of N-acetylglucosamine. Its compact crystal structure makes it insoluble in water, dilute acids, alkalis, alcohols and other organic solvents. This limits its scope of application to some extent. However, chitosan, the product of deacetylation, has improved solubility due to the additi...
