Abstract

The adsorption of organic content from produced water by acid treated castor oil (CO) biomass was investigated. Batch adsorption experiments were carried out as a function of pH, contact time and adsorbent dosage. Organic adsorption equilibrium was rapidly attained after 60 minutes of the contact time. The removal of oil reached 83.5% and 97.5% with 1.5 g dose, 120 min with pH = 3 at constant temperature (25 oC) for castor and modified castor oil. The aptitude of castor oil to adsorb oil was augmented subsequently by addition of different amounts at regular mixing time between 30 and 60 min. Freundlich and Langmuir models were rummage-sale aimed at the fitment of batch experimental data, then it was experiential that Freundlich model was originate to decide by the values got by research founded on reversion examination. Castor oil brand demeaning fully despite its high aptitude to adsorb organics from the produced water.
