| Abstract: |
In this work, nanocellulose (NC), modified nanocellulose (pM-NC) and MOF composites (ZIF-8/pM-NC) were synthesized from Moringa olifera seed pod and were used for the dye adsorption. Samples were synthesized in aqueous media by one pot green methods. The prepared nanocellulose crystals were phosphorylated using orthophosphoric acid. Nano-sized cellulose ester derivatives having phosphoryl side groups were synthesized by the green phosphorylation of nanocrystalline cellulose, using water, then processed with phosphoric acid. Phosphorylated nanocellulose was added in the ZIF-8 precursor solution and sonicated to make MOF- nanocellulose composites. Structural investigation was performed using Fourier Transform Infrared Spectroscopy (FT-IR), which indicated the progressive removal of non-cellulosic constituents. Morphological study was conducted using Scanning Electron Microscopy (SEM). X-ray diffraction (XRD) analysis revealed the increased crystallinity with successive treatments. Removal efficiency of Rhodamine-B dye by nanocellulose, phosphorylated nanocellulose and ZIF-8/pM-NC was studied. Influence of dosage of the adsorbent, pH, temperature and time were analyzed for the cationic dye removal. Increase in pH 6–12 was accompanied by an increase in the rhodamine dye adsorption. Taguchi L9 orthogonal array have been used for designing the experiments and the most influenced factors were selected and modeled by the RSM (BBD) method to obtain the highest percentage of rhodamine dye removal.
