Real Silk Degumming Wastewater Remediation: Simple Applicable Recovery of Sericin Micro and Nano powders
Author(s):
Abstract:
in this study, an effectual ecofriendly technique for recycling of sericin has been developed. Pure sericin powders in the range of micro to nano scale were prepared by processing of real silk industry wastewater. Sericin was extracted through different procedures using urea and ethanol incorporating by spray drying and rotary extraction to acquire the desired powders. The obtained powders were evaluated using UV-vis spectrophotometer and Field Emission Scanning Electron Microscope to choose the best in the aspect of size and morphology. Fourier transform infrared spectroscopy spectra of sericin showed an absorption band at 1650 cm−1 (amide I), indicating random coil conformation. The structural properties of the produced micro and nano sericin powders were investigated using Xray diffraction and differential scanning calorimetry analysis, which revealed that chemical precipitation can affect the secondary structure of sericin may arise from the intermolecular hydrogen bond changing.
