Description
Technical field
The present invention relates to a kind of preparation methods of antibiont support type collagen fiber adsorption material, belong to sorbing material technology
Field.
Background technology
Collagenous fibres are the linear chain structure albumen of a kind of appearance white, transparent natural fiber, are largely present in lactation
The skin histology of class animal is tied in hoof tissue and bone tissue, and content accounts for about 25%~33% left side of animal vivo protein total amount
The right side is the most protein of animal in-vivo content, has very important effect to protection body, support organ.According to collagen
Fiber to the difference of animal body concrete function, can generally be classified as basement membrane collagen, non-dimension collagen, anchoring collagen, cross-film collagen,
Fento collagen, the netted collagen in six sides and collagenous fibres with other special roles etc..In α-peptide chain of collagenous fibres molecule
Containing a large amount of acid and alkaline amino acid residue, all there are carboxyl and amino in every peptide chain both ends, therefore collagenous fibres have
Certain isoelectric point is a kind of amphiprotic substance.In addition, also containing a large amount of-COOH ,-NH in collagenous fibres molecular side chain2、-
NH-CO- ,-OH isoreactivity group have very high chemism in aqueous solution, can be combined with water molecules hydrogen bond, hydrophilic insoluble
Yu Shui, in water in solvent swelling state, therefore the water absorbing capacity of collagenous fibres is very strong.In addition, peptide is existed simultaneously between collagenous fibres
Ionic bond, hydrogen bond, Van der Waals force, hydrophobic bond and intermolecular Aldehyde-ammonia Condensation, aldol condensation and aldehyde alcohol histidine between chain
The effects that power so that being completely embedded between tropocollagen molecule, the comprehensive strength for leading to collagenous fibres are higher.These knots of collagenous fibres
Structure feature determines the good characteristics such as its good mechanical strength and stronger biocompatibility, increasingly causes researcher's
Extensive concern.
Collagenous fibres are emerging with the research that its unique structure and biology performance increasingly cause absorption both at home and abroad to learn expert
Interest, and its application in Industrial Wastewater Treatment is also increasingly extensive, cannot be only used for the metal ions waste water such as Cr, Cu, Fe
Adsorption treatment, it may also be used for the substances such as the removing of tannin and Wastewater Dyes, enzyme, microorganism and protein in Chinese medicine preparation
Removal.In addition, pretreatment, chemistry are passed it through containing a large amount of collagenous fibres in the solid waste generated in leather making process
Industrial wastewater is handled as sorbing material after the processes such as modified, efficiently using for Leather Solid Waste can be not only realized, subtract
Few environmental pollution, and the processing cost of industrial wastewater can be also reduced, enhance economic benefit, there is higher researching value.But
Be existing collagenous fibres sorbent material due to being collagen-based materials, easily by microorganism and bacterial load, block absorption hole, lead
Sorbent material absorption property is caused to lower, absorption is invalid, so prepare a kind of sorbent material of effective antibiont load has very much
It is necessary.
