Exploring The Potential Of Cacao Pod Husk As An Adsorbent Of Simulated Water Pollutants

This study evaluated the levels of heavy metals, namely cadmium, lead, and mercury, from key aquatic fauna and sediments from seven strategicotentials of the Philippines.The researchers explore the potential of activated carbon using cacao pod husk, using only a single chemical agent to successfully achieve the toxic metal pollution.The results indicate that the 50% KOH concentration yielded the highest mean adsorption efficiency (0.66 ppm), followed by the 70% KOH (0.38) concentration (0.58) concentration, and lastly, the absence of KOH resulted in the lowest average amount of Lead (Pb) and Cadmium (Cd).The computed pvalue (2.920) and coefficient of variation (C.V = 0.53) indicate that there is no statistically significant difference in adsorption efficiency across the different concentrations.These findings highlight how using chemicals to activate the carbon improves its ability to absorb these metals, making it a practical and ecofriendly option for cleaning up polluted water.
