ZnO-modified activated carbon derived from rambutan ( Nephelium lappaceum ) peel and seeds for efficient methylene blue removal: adsorption mechanism and artificial neural network modeling
Abstract
= 0.921; RMSE = 5.86). Sensitivity analysis identified temperature and adsorbent dosage as the most influential factors, consistent with thermally activated adsorption and active-site accessibility inferred from surface and thermodynamic analyses. Regeneration trials indicated maintained performance during initial cycles, followed by a noticeable decline upon repeated use, while structural features remained preserved. Dual-precursor compositional control and ANN-assisted analysis establish a framework for understanding structure-performance relationships in ZnO-carbon systems, while providing a basis for future evaluation under more complex wastewater conditions.
