Synthesis and Adsorption Performance of Carbon Materials for the Removal of Iron (III) from Aqueous Solution

Abstract:

Carbon nanofibers prepared from Ni catalyst supported on activated carbon and pre-treated activated carbons show the potential in removing borderline and soft metal Fe (III) ions in single solutions over a wide range of concentrations. The morphological and textural properties of the carbon material were studied using the Scanning Electron Microscope (SEM) and Nitrogen adsorption isotherm method. Continuous column adsorptions were conducted to study the adsorption performance. The results showed that the percentage of Fe (III) removal starts to increase at the initial concentration of 10 mg/L. The percentage of Fe (III) removal continues to increase until it reaches the maximum removal at 60 mg/L. The value of correlation (R²) indicates that the data on carbon-based adsorption of Fe (III) may be concluded to perfectly fit the Langmuir isotherm model confirms the monolayer adsorption. Thus, this study is relatively useful in considering an appropriate technology for designing a suitable wastewater treatment plant.
