Synthesis of N-Methyl-D-Glucamine Modified Chitosan Nanofibers for Boron Adsorption
摘要
The N-methyl-D-glucamine modified chitosan nanofiber was synthesized using chitosan nanofiber. It was synthesized by reacting chitosan nanofiber with D-glucose and NaBH3CN to obtain D-glucamine-modified chitosan nanofiber, followed by the reaction with formic acid and formaldehyde. After swelling with water, the contained boron was removed by condensing with NaHCO3. The maximum value of boron adsorption was 12.8 mg g−1 (equilibrium concentration, Ce = 179 ppm) and the value was higher than non-nanofiber N-methyl-D-glucamine modified chitosan obtained in the previous study.
