DETERMINATION OF ADSORPTION OF BLUE DYE USING SUGARCANE BAGASSE IN AN AQEOUS SOLUTION

Abstract

This research provides valuable insights into using raw sugarcane bagasse (SB) as an adsorbent for dye removal from wastewater. Various activation and modification methods for SB were explored, including physical, chemical, and biological treatments, as well as composite formation and grafting. The study examined the effects of different optimization conditions on the adsorption process, such as adsorbent dosage, initial dye concentration, pH, and contact time. Key findings include an equilibrium contact time of 30 minutes for methylene blue dye, resulting in an 86% removal rate. The optimal pH for dye removal was identified as pH 6, achieving an 84% removal rate. The study also found that the optimum dye concentration for removal was 10 ppm, with a 70% removal rate, and the optimal adsorbent dosage was 0.4g, resulting in an 81% removal rate. These results demonstrate the effectiveness of raw sugarcane bagasse in adsorbing methylene blue dye under specific conditions, highlighting its potential as a low-cost and efficient adsorbent for wastewater treatment.
