Adsorption of reactive blue 49 onto cross-linked chitosan-based composites containing waste mussel shell and waste active sludge char

Cross-linked chitosan/waste mussel shell (C/WMS) and chitosan/waste mussel shell/waste active sludge char (C/WMS/WASC) composites were prepared from waste mussel shell, waste active sludge (WAS), and chitosan, and cross-linked with glutaraldehyde. The quantities of chitosan, WMS, and WASC used for t...
