AMINE GRAFTED CHITOSAN NANOFIBER, METHOD FOR PREPARATION THEREOF AND ITS USE IN HEAVY METAL ADSORPTION

The present invention relates to an amine grafted chitosan nanofiber having the formula (I) wherein R1 to R5 are independently selected from linear or branched C1-C20 alkandiyl C6-C24 arenediyl; k and m are independently selected from 1 to 10, wherein, in case that k and/or m are >1, each R4 and...

Beschreibung
Zusammenfassung:	The present invention relates to an amine grafted chitosan nanofiber having the formula (I) wherein R1 to R5 are independently selected from linear or branched C1-C20 alkandiyl C6-C24 arenediyl; k and m are independently selected from 1 to 10, wherein, in case that k and/or m are >1, each R4 and R5 group can be independently selected; and 1 and n are independently selected from 50-3000, a method for the preparation thereof and its use in heavy metal adsorption.
