Kinetics, isotherm and thermodynamic studies on the adsorption of methylene blue dye by iron doped activated carbon

The present study details the synthesis and characterisation of iron (Fe) doped activated carbon from Alstonia Scholaris (AS-Fe) natural wood waste. Investigation addresses the utilization of natural wood waste for useful and potential high temperature Alstonia Scholaris activated carbon (HT-AS). Iron doped activated carbon (AS-Fe) is used for the treatment of industrial waste water. Activated carbon and utilization performances are well attributed to the preparation methods and hence a range of characteristic interpretation like Fourier transform spectroscopy (FTIR), X-Ray powder diffraction, UV-Vis spectra, Field emission Scanning Electron Microscopes (FE-SEM) and EDAX analysis are evaluated. The result of AS-Fe is well distinguished by comparing the features with the porous high temperature Alstonia Scholaris activated carbon (HT-AS). High-performing iron doped activated carbon (AS-Fe) developed from natural wood waste reveals a distinct advantage in the adsorption approach for the removal of organics such as synthetic textile colours from industrial wastewater.
