College, Kota, Rajasthan (INDIA) <p>Dye stuff production units have always had a pressing need for techniques that allow economical pretreatment for color in the effluent. Reactive black 5 dye (RB5), a remazol type dye, used in various industries has eco-toxic hazardous effects and is a major cause of pollution in waste water system.</p> <p>In this study fly ash from coal burning power plant was activated chemically, used as a low cost adsorbent for the removal of reactive black 5 dye. The activated fly ash was characterized by XRD. Results showed that activated fly ash due to increased amorphous property possesses more activity over surface to act as a suitable adsorbent for the removal of dye waste from industrial effluents. The adsorption kinetics is well represented by first order kinetic model.</p> https://journalofchemistry.org/paper/610/ Reactive black 5 dye fly ash alkali activation adsorption.
