ABSTRACT
Cellulose and silk fibroin were dissolved in 1-Butyl-3-methylimidazolium chloride [Bmim][Cl] and regenerated with ethanol to form homogenous blend of regenerated cellulose/silk fibroin. The bioactivity of regenerated cellulose/silk matrix to assist calcium phosphate mineralization was studied in the current article. Cellulose/silk fibroin/calcium phosphate biocomposite was investigated by different characterization methods such as FT-IR, XRD, TGA, SEM and EDX. The potential of the prepared composite for removal of organic dyes, such as methylene blue (MB), was calculated. The prepared biocomposite exhibited high removal efficiency for MB (172.4 mg/g) compared to regenerated cellulose/silk fibrin blend which is 120.4 mg/g. The kinetic study and the isotherm results for the examined materials followed pseudo second order and Langmuir models, respectively. The regenerated cellulose/silk/calcium phosphate biocomposite, thus providing prospects for further research and application in the remediation of water from dye pollution.
