Removal of Reactive Dye from Aqueous Solution Using Coagulation–Flocculation Coupled with Adsorption on Papaya Leaf

Attempts were made to investigate the effectiveness of a combined process of coagulation–flocculation and adsorption for the removal of reactive dye (Reactive Red 3BS) from aqueous solution. The effluent obtained from the coagulation–flocculation process was the raw solution for the second step of...
