Abstract/Executive Summary
In local communities, limited access to piped water services leads to reliance on natural sources such as lakes and rivers. However, these sources are increasingly polluted by industrial effluents, agricultural runoff, and improper waste management, posing significant threats to ecosystems, public health, and community well-being. This study explores the utilization of Mango Peel Activated Carbon (MPAC), derived from ripe mango (Mangifera indica) peels, as a biosorbent for removing Iron (III) from aqueous solution, which underwent a sequence of physical and chemical activation processes. This examined key parameters such as A: adsorbent dosage (0.025–0.1 g/L), B: contact time (15–35 minutes), and C: temperature (25–35 °C), in order to assess its potential as a sustainable clean water solution. Optimization of experimental parameters and statistical analysis was conducted using the JMP Pro 18 Software, applying the Box-Behnken Design (BBD), under Response Surface Methodology (RSM), to identify the most effective conditions for iron removal. The highest observed percentage removal was 29.02%, with optimization predicting a maximum of 12.9% efficiency under conditions of 0.0625 g/L dosage, 25-minute contact time, and 30 °C temperature, with a desirability score of 0.489. Analysis of variance (ANOVA) confirmed the statistical significance of the model (p = 0.0083), identifying adsorbent dosage and its interaction with temperature as the most influential factors. These findings align with prior studies on activated carbon and other modified adsorbents, which similarly demonstrate enhanced adsorption capacities at increased adsorbent dosages, extended contact times, and elevated temperatures.
