dc.description.abstract	2-naphthol is a hazardous chemical and its exposure is possible in our routine life. To minimize the effects of its exposure, its adsorption on suitable adsorbents is necessary. In this work, batch equilibrium studies have been conducted to remove the pollutant from aqueous solutions onto Amber lite XAD-4 resin. The effect of pH (2, 4, 6 and 8), shaking time (15, 30, 45 and 60 min), the concentration of substance (0.00 10, 0.0015, 0.0020, 0.0025, 0.0030 M) and the amount of adsorbent (0.5, 1.0 and 1.5 g) on percent adsorption of 2-naphthol has been investigated. The concentration of 2-naphthol has been monitored on a UV-visible spectrophotometer at 273 nm detection. From the experiment, the optimized condition for adsorption of 2-naphthol onto Amberlite XAD-4 are pH (2), agitation time (60 min), concentration (0.00 I OM) and amount of adsorbent ( 1.5 g). The data also fits to the sorption dynamic module (Lagergren equation and Morris-Weber equation) and sorption isotherm module (Freundlich isotherm, Langmuir isotherm, and Dubinin-Radushkevich (D-R) isotherm).	en_US
