Abstract/Executive Summary

Freshwater scarcity and pollution, exacerbated by industrial activities such as textile and cosmetic production, are critical global challenges, with synthetic dyes like methylene blue (MB) posing significant environmental and health risks. In the Philippines, the widespread pollution of water bodies from industrial effluents, including synthetic dyes, further worsens the situation, highlighting the need for innovative and sustainable water treatment solutions. This research aims to investigate the use of coconut shell-derived activated carbon as an adsorbent for MB removal from aqueous solutions, exploring the impact of factors such as dosage, initial pH, and contact time on adsorption efficiency. The primary objective is to optimize these parameters through a Box-Behnken Design to enhance the adsorption capacity of coconut shell-derived activated carbon. A series of controlled laboratory experiments will be conducted to assess the material's efficiency under varying conditions. Preliminary findings suggest that coconut shell-derived activated carbon can effectively adsorb MB, with optimal performance achievable under specific conditions. This research contributes to advancing low-cost, sustainable solutions for water purification, with significant implications for the treatment of polluted water in the Philippines and other regions facing similar environmental challenges.
