Abstract
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 m2 g–1) 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.
