Preparation and Use of Aqueous Solutions Magnetic Chitosan / Nanocellulose Aerogels for the Sorption of Reactive Black 5

Abstract

For the disposal of Reactive Black 5 from aqueous solutions, the hydrophilic, magnetic, and extremely porous aerogels derived from rice straw waste have been synthesized. The first rice straw was made of nanocellulose crystals. Instant gelation and cross-linking processes were then used to prepare magnetic chitosan/nanocellulose aerogel beads. The aerogels have been distinguished by different technology, namely FT-IR, TEM, EDX, DLS and VSM. Results revealed the effective preparation of magnet chitosan / nanocellulose aerogels. Reactive Black 5 can be removed in acidic media and at a time of touch of 30 minutes. The aerogels absorbed color should be used as a dye color in textile printing. Secondary emission can be avoided. The future use of magnet chitosan / nanocellulose aerogels as an absorbent color can be based on its simple environment, using minimum precursor effort.
