Adsorption Kinetics of Acid Red on Activated Carbon Web Prepared from Acrylic Fibrous Waste

Popis výsledku v původním jazyce

In this work, activated carbon (AC) web was prepared using physical activation under the layer of charcoal in high temperature furnace. The carbonization of acrylic fibrous waste was performed at different temperatures (800 ◦C, 1000 ◦C and 1200 ◦C) with heating rate of 300 ◦C hr-1 and at different holding time. At 1200 ◦C, the heating rate of 300 ◦C hr-1 and no holding time provided better results of surface area as compared to carbonization at 800 ◦C and 1000 ◦C. The activated carbon web (AC) prepared at 1200 ◦C was used for removal of Acid Red 27 dye from aqueous media by varying different parameters like initial concentration of dye, stirring speed, adsorbent dosage and pH. The results were evaluated by using non-linear forms of Langmuir and Freundlich isotherms. The Freundlich isotherm was found to describe the results more effectively because of nonhomogenous surface of activated carbon web. Further, the kinetics of adsorption was examined by using linear and non-linear forms of pseudo 1st order and pseudo 2nd order.
