Removal of Acidic Dye (Acid Violet 4bs) From Aqueous Solutions Using Modified Forms of Adsorbents
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 10
Abstract
This research work deals with the application of using Sawdust (SD), Activated Carbon (AC) and PolyAniline coated SawDust (PAn/SD) produced from the plant of Calotropis Gigantea (CG) for the removal of Acid Violet 4BS dye from aqueous solutions. Adsorption experiments were carried out using batch mode technique. The effects such as adsorbent dose, initial dye concentration, pH and contact time were then studied. The maximum dye removal was found to be at natural pH for all the modified forms of adsorbents. A comparative study was made and it was found that the maximum percentage of dye removed by CGSD was 50.40%, for CGAC was 59.42% and for CGPAn/SD was 84.88%. Hence the study proved that CGPAn/SD is an efficient adsorbent compared to other forms for the removal of Acid Violet 4BS dye from aqueous solutions.
