Removal of Erythrosine Using Bottom Ash as an Adsorbent

Abstract

This research explores the use of bottom ash, a byproduct of coal-fired power plants, as a cost-effective adsorbent to remove the hazardous dye erythrosine from wastewater. Erythrosine, commonly used in various industries, poses significant environmental and health risks due to its persistence and toxicity. Additionally, the disposal of bottom ash faces challenges due to limited disposal sites, creating potential environmental pollution concerns. This study aims to optimize the adsorption process by evaluating the effects of pH, dye concentration, and adsorbent dosage on removal efficiency.
