| This study evaluates the effectiveness of natural adsorbents in removing water pollutants. Natural heulandite zeolite from Qom mines was sampled, prepared, and tested for the removal of methylene blue (MB) and methyl orange (MO) dyes from aqueous solutions. The zeolite was characterized using XRD, XRF, and ICP analyses, confirming its composition as Ca₁.₂₃(Al₂Si₇)O₁₈·6H₂O (or CaAl₂Si₇O₁₈·6H₂O), with heulandite as the primary component. The dye removal efficiency was measured via UV-Vis spectroscopy at wavelengths of 665.0 nm (MB) and 465.0 nm (MO). Results demonstrated removal efficiencies of 100% for MB (a cationic dye) and 43.7% for MO. The near-complete adsorption of MB suggests that heulandite zeolite is highly effective for cationic dye removal, potentially reducing energy consumption in water purification processes. | ||
