Banana blossom peels adsorbent for the removal of manganese in water

Manganese is one of the persistent heavy metals detected in surface water lately that has become an environmental concern because manganese poses negative impacts to the ecosystem and water supply. This study investigates the effectiveness of banana blossom peels (BBP) as an adsorbent for the remova...

This study investigates the effectiveness of banana blossom peels (BBP) as an adsorbent for the removal of manganese in water. The BBP adsorbent was activated via chemical treatment method.

FESEM-EDX analysis showed the morphology of BBP adsorbent was crimped with deeper dents, rough internals surface, and dense in nature, providing maximum surface area for the adsorption process.

Batch adsorption study evaluated the parameters affecting the adsorption process, which include pH, adsorbent dosage, initial manganese concentration, and contact time. The optimum condition was attained at pH 7, adsorbent dosage of 0.5 g, 10 mg/L initial manganese concentration, and 150 minutes contact time.
