A Facile Route for Removal of Reactive Dye Red 195 by Using Geopolymer Based on Bentonite.

Abstract

The fundamental circulation of life on earth depends on water. Clean water resources have suffered as a result of increased industry and urbanisation. The water resources have been contaminated by a variety of pollutants, including pesticides, heavy metals, and dyes. The most widely used method for removing heavy metals, dyes, and other contaminants from wastewater is adsorption because it is efficient, easy to use, and affordable. In the current work, the possible utility of bentonite based geopolymer as a low-cost adsorbent to remove reactive red 195 dye from wastewater was thoroughly examined. The pH value, duration, geopolymer dose, and dye concentration are the different parameters used to defines the reactive red 195 dye's adsorption mechanism.
