Abstract:
This study aims to explore the removal analysis of Methylene Blue (MB) and Brilliant Green (BG) dyes from aqueous solutions through adsorption on modified activated carbon. The activated carbon was prepared by chemically activating coconut shells, eucalyptus trees, corn cobs, and flamboyant pods. Remarkably, the highest percentage of Methylene Blue removal was achieved with 95.0% for coconut shells, 93.2% for eucalyptus trees, 99.9% for corn cobs, and 99.7% for flamboyant pods, all with an adsorbent dosage of 5g per 0.003mL. Similarly, the maximum percentage of Brilliant Green removal was observed as 97.0% for coconut shells, 98.2% for eucalyptus trees, 99.6% for corn cobs, and 99.6% for flamboyant pods, using the same adsorbent dosage.
The adsorption isotherms for this process were investigated, with the Freundlich model demonstrating the best fit for the equilibrium data. To optimize operational conditions, we conducted experiments examining the effects of contact time, adsorbent dosage, and pH using a two-level factorial experimental design approach. Interestingly, the adsorbent dosage emerged as the most significant factor, falling below a 95% confidence level with P = 0.0008 for Methylene Blue and P = 0.0069 for Brilliant Green. These results hold great promise, as the activated carbon derived from these agricultural waste sources played a pivotal role in effectively adsorbing the dyes.
