Removal of methylene blue from aqueous solution by using iron impregnated activated carbon web from waste acrylic fibres

Popis výsledku v původním jazyce

In this study, the acrylic fiber waste was successfully converted into AC and iron impregnated activated carbon (FeAC) through physical activation in the presence of air by using thermal treatment process in the high temperature muffle furnace. The adsorption phenomenon in terms of adsorption capacity and dye removal percentage was investigated by varying dye concentration, FeAC dosage, different stirring speed and pH (2-10) values of solution. The results showed that dye removal time is increased when the concentration of dye is increased in solution. The results were analyzed using adsorption isotherms (linear and non-linear forms of Langmuir and Freundlich) and adsorption kinetics (linear and non-linear forms of pseudo 1st and pseudo 2nd order models). By comparing the results of pseudo first and second models, it is clear that nonlinear models give more reliable and close results with experimental values. On the basis of this study it is concluded that iron impregnation before carbonization can be effectively employed for the removal of cationic dyes from waste water. The current book is the THIRD in a series of manuscripts under “PROGRESS IN FIBROUS MATERIAL SCIENCE”. These books are collection of chapters dealing with state of the art technologies and the science of polymeric materials in specific.
