Abstract
This study investigates the use of activated carbon derived from mango (Mangifera indica) seed coats for the removal of cadmium (Cd²⁺) from aqueous solutions. Batch experiments were carried out to examine the effects of varying initial metal concentrations (10–50 ppm) and adsorbent dosages (0.1–0.5 g) at a constant pH of 5. Residual cadmium levels were measured using atomic absorption spectroscopy (AAS).
Results showed that adsorption efficiency increased with higher initial concentrations, reaching 80.78% removal at 50 ppm with 0.5 g of adsorbent. In contrast, increasing the adsorbent dosage above 0.1 g at a constant 50 ppm showed minimal improvement, suggesting early site saturation. The activated carbon demonstrated strong affinity for cadmium, highlighting its potential as a low-cost, eco-friendly adsorbent.
Overall, mango seed coat-based activated carbon shows promise for effective cadmium
removal in water treatment.
