Comparative Study of Chitosan and Silk Fibroin Staple Microfibers on Removal of Chromium (VI): Fabrication, Kinetics and Thermodynamic Studies

Popis výsledku v původním jazyce

Short staple microfibers (SSM) based on chitosan (CS) or silk fibroin (SF) were fabricated via the wet-rotate-spinning technique and employed to adsorb hexavalent chromium from aqueous solution. Adsorption efficiencies of CS and SF-SSM were systematically investigated and the physicochemical and morphological properties of CS/SF-SSM were evaluated before and after adsorption of Cr(VI) using different techniques like ATR-FTIR, TGA, XRD, XPS, and SEM. CS and SF-SSM showed removal efficiency (> 90 %) toward Cr(VI) ions. Pseudo-second order kinetic and Langmuir isotherm models could describe the Cr(VI) ions uptake process. Considering the inexpensive, sustainability and higher adsorption capacity of CS, and SF-SSM hold great promising applications as natural adsorbent materials for removing different hazardous metals from aqueous medium.
