Abstract
The main aim of this study is investigation of the reactive dye removal efficiency from wastewater by using nanofibers functionalized with β-cyclodextrin(βCD) through the immersion method. At first, polyacrylonitrile(PAN) nanofibers for the removal of three reactive dyes of CI Reactive Blue 13, C.I. Reactive Blue 21 and C.I. Reactive Red 2 from simulated wastewater were used. The dye removal efficiency for the dyes mentioned was 4.7, 22.5 and 3.4 %, respectively. Then, PAN/βCD10 and PAN/βCD50 nanofibers, which had 10 and 50 wt% of βCD, respectively, were electrospun. It was found that dye removal efficiency of PAN/βCD10 nanofiber mats for the dyes mentioned was 8.3, 28.1and 10 %, respectively. Also, dye removal efficiency of PAN/βCD50 nanofiber mats was obtained to be 31, 49 and 25%. Based on the results, dye removal efficiency of reactive dye wastewater was increased due to the increase in βCD concentration. Increasing PAN/βCD50 nanofibers weight from 0.01 to 0.1 g tended to increase dye removal efficiency of C.I Reactive Blue 21 dye wastewater from 49% to 86.4%.
