Adsorption of SO2 on Wool Fiber: An Experimental and DFT Study
MetadataShow full item record
In this study, the washed-combed wool fiber and the washed-combed-dyed wool fiber were used to investigate pollutant gas sorption capacity of wool fibers. Sulfur dioxide (SO2) was selected as the pollutant gas since it is one of the mostly found pollutants in air content. The wool fiber samples were tested with gaseous pollutant for different time periods and gas adsorption values were measured. Furthermore, SO2 adsorption was studied theoretically by density functional theory (DFT) calculations with B3LYP 6-31 G (d,p)/method on amino acids were found to be in good agreement with experimental data.
