Abstract

This study explores the adsorption performance of acid-modified Philippine Natural Zeolites (PNZs) in treating industrial wastewater from Valenzuela City, Metro Manila. The adsorption capability of acid-modified zeolites (AZ+) was compared to the activated PNZ granules (Z) through the batch adsorption process. Kinetic models were employed to determine the adsorption mechanism of each sample. The results show that acid-modified PNZs follow a pseudo-second-order (PSO) kinetic model, implying that chemisorption, specifically ion exchange, is the primary adsorption process. The increased equilibrium adsorption capacity (q_e) of AZ+ granules with 91.5692% implies that acid-modified PNZ granules are viable materials for sustainable wastewater treatment in the region.
