Activated Carbon Sorbents Prepared from Acrylic Fibrous Wastes

Popis výsledku v původním jazyce

Activated carbon web is prepared by controlled pyrolysis of acrylic fibrous waste under the layer of charcoal using physical activation in high temperature furnace. The carbonization was carried out at 1200 oC under different heating rate (i.e. 150 to 450 oC hour-1) with different holding time (i.e. 0 to 60 min) to decide optimum pyrolysis parameters. The heating rate of 300 oC hr-1 with no holding time revealed higher specific surface area of 280 m2g-1. The prepared activated carbon web was later employed as adsorbent for removal of methylene blue from aqueous media. The effect of initial dye concentration, adsorbent dosage, stirring speed and pH of solution was studied. The obtained results were later compared with adsorption isotherms (i.e. Langmuirand Freundlich). The Freundlich model was found to fit closely with results due to heterogeneous adsorption of dye molecules. Finally, virgin activated carbon and dye adsorbed activated carbon were tested for desorption behavior using di
