Catalytic Effects of Different Metal Salts on Cotton Waste Textiles by Pyrolysis: Pyrolysis Behavior and Properties of Activated Carbon
This study was conducted to explore the catalytic effects of different metal salts on the pyrolysis behavior of cotton waste textiles (CWTs) and the properties of their activated carbons (ACs). The decomposition characteristics of CWTs with Zn, Fe, and Cu salts were studied by thermogravimetric anal...

| description | This study was conducted to explore the catalytic effects of different metal salts on the pyrolysis behavior of cotton waste textiles (CWTs) and the properties of their activated carbons (ACs). The decomposition characteristics of CWTs with Zn, Fe, and Cu salts were studied by thermogravimetric analysis (TGA) to analyze the catalytic effects. The physical and chemical characteristic differences of the ACs were detected with SEM-EDS, BET, FTIR, and XPS. The results show that metal salts reduced the decomposition temperature of the CWTs and improved the pore structures and specific surface areas of the activated carbons (ACs). The ACs produced abundant acidic surface functional groups on their surfaces, which facilitated the selective adsorption of pollutants. This study indicates that cotton waste textile biochar treated with metal salts may be a promising adsorbent for the removal of heavy metals and organic pollutants. |
