  Abstract

In the present work, poly(vinyl alcohol)/silk sericin (PVA/SS) membranes were obtained with an easily procedure and removal of remazol black B (RBB) by the membranes was investigated. To synthesize PVA/SS membranes by solvent casting method, 5% SS solution (g/mL) and 10% PVA solution (g/mL) were mixed one to one ratio by volume, the mixture was transferred to a petri dish and incubated at 25 ºC for 24 h. Then, the obtained membranes were incubated at 150 ºC for 1 h for physical crosslinking. The obtained membranes were characterized with fourier transformed infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and thermogravimetric analysis (TGA). Then, for adsorption experiments, firstly, RBB adsorption capabilities of PVA/SS membranes were tested at pH ranging from 2 to 7. After that, the removal experiments were carried out at different incubation time, initial dye concentration and PVA/SS membrane amount to optimize the conditions for removal of RBB with the PVA/SS membranes. The obtained membranes removed high amount of RBB when the solution pH was 2 and the adsorption of RBB to the membranes reached equilibrium within 10 h. The maximum RBB adsorption ability of the PVA/SS membranes was found to be 15.27 mg/g when the initial RBB amount of the solution was 200 mg/L. These results show that PVA/SS membranes, which can be easily synthesized for large applications, have the capacity to be used to remove negatively charged pollutants such as RBB from liquid solutions.
