AB  - This study was aimed at evaluating the possible use of oil-rich sludge as adsorbents for dye removal. The sludge-adsorbents were prepared through treatment using HCl and KOH andwere then characterized according to BET surface area and surface functional groups. Rhodamine B was selected as model dye andbatch equilibrium adsorption of dyewas performed with the treated and untreated adsorbents. The result shows that the BET surface area for KOH-treated adsorbent is the highest (2.08 m<SUP>2</SUP> g<SUP>&#150;1</SUP>) compared to the other two samples. The equilibrium adsorption capacity was well correlated with the specific surface area of adsorbents. Also, the Langmuir model was well-fitted to the adsorption data, suggesting that the adsorption is monolayer in nature and is possibly of a chemical-type. With suitable treatment, oil-rich sludge could be a promising adsorbent for dye removal from water.
