Removal Of Reactive Blue 19 From Aqueous Solution And Industrial Wastewater Using Activated Carbon And Iron Modified Activated Carbon

In this research, iron modified activated carbon (FeAC) was prepared through chemical activation method to enhance the adsorption potential of activated carbon (AC) towards the removal of Reactive Blue 19 (RB 19) dye in industrial wastewater and aqueous solution. The adsorbents were characterized by...
