ADSORPTION PROPERTIES OF ACTIVE MgO FOR THE REMOVAL OF DYE POLLUTANTS FROM WASTEWATER

摘要

Active MgO was employed as an adsorbent to explore its capacity and cycle performance of removing azo dye reactive brilliant red X-3B from solution. Experimental results indicate that active MgO has a good adsorbent capacity. The percent removal of reactive brilliant red X-3B increases to about 99.5% with increasing the dose of active MgO to some extent. Adsorption capacity of active MgO was not reduced after ten cycles as recyclable material. The experimental results showed that active MgO was a promising adsorbent to treat wastewater containing the dye.
