Preparation method of chitin/zinc compound bactericide

Abstract

A composite chitosan / Zn antibacterial agent with broad spectrum is prepared from chitosan and Zn ions through ionic coordination, depositing in the mixture of acetone and alcohol, washing and drying.

Description

Technical field

[0001] The invention relates to a method for preparing a novel antibacterial agent by using a metal zinc complex of natural renewable resource chitosan, and belongs to the field of renewable resource chemical biology. Background technique

[0002] Chitin is a natural polysaccharide extracted from the crustaceans of shrimps, crabs and other crustaceans and the cell walls of fungi. It is also the second largest biomass resource in nature after cellulose. Chitosan is a deacetylated derivative of chitin. It has good biocompatibility, biodegradability, natural non-toxicity and a variety of biological activities, especially spectral antibacterial properties, and because of its molecular chain has many amino groups Active groups such as, hydroxyl, etc. have high reactivity and are easily complexed with transition metal ions. In recent years, chitosan has received widespread attention as a natural antibacterial agent. However, compared with traditional antibacterial agent...
