Immobilization of Bacillus subtilis bacteria into Biohybrid Crosslinked Chitosan-glutaraldehyde for acid red 88 Dye Removal: Box-Behnken Design Optimization and Mechanism Study
Herein, a novel biomaterial of crosslinked chitosan-glutaraldehyde combined with Bacillus subtilis biomass (CHS-GLU/BCL) was synthesized via hydrothermal synthesis to effectively remove the anionic dye (Acid red 88; AR88) from synthetic wastewater solution. The physicochemical properties of the CHS-...
