Effectiveness of Kepok Banana Peels to Reduce Iron (Fe) in Laboratory Wastewater

Abstract

Introduction: Kepok banana peels contain fiber, cellulose, and lignin, which play a significant role in the adsorption process. These peels offer advantages as adsorbents due to their low cost, availability, and environmental friendliness. This study explores their potential as an alternative solution for treating Fe-contaminated wastewater.

Objectives: This study aimed to evaluate the effectiveness of Kepok banana peel as an adsorbent for removing iron (Fe) from laboratory wastewater.

Methods: The banana peels were processed into adsorbent material by chemical activation using 1 N HCl and sieving to 100 mesh. Various adsorbent dosages and stirring speeds were tested to determine optimal conditions.

Results: The adsorption process followed the Langmuir isotherm model, indicating monolayer adsorption with strong chemical interactions. Kepok banana peel is proven to be an effective and sustainable adsorbent for reducing Fe levels in wastewater.

Conclusions: The adsorption process followed the Langmuir isotherm model, indicating monolayer adsorption with strong chemical interactions. Kepok banana peel is proven to be an effective and sustainable adsorbent for reducing Fe levels in wastewater.
