AbstractBatch adsorption of lignosulfonates using untreated powdered eggshell under the influences of mixing times, pH, particle size and dose of powdered eggshell was investigated. Adsorption isotherms of lignosulfonates onto powder eggshell were also studied. Eggshells were collected from the Balubur traditional market in Bandung, Indonesia, washed with distilled water, air dried, and then ground into powder of different particle sizes. Kinetic studies found that equilibrium time was as high as 90 minutes. From experiments carried out at different pH, it was observed that pH plays an important role in the adsorption of lignosulfonate compounds. The optimum dosage of powdered eggshell was 30 g/100 mL of 500 mg/L lignosulfonates solution. Adsorption isotherms studied through the use of graphical methods revealed that the adsorption of linosulfonates onto powdered eggshell follows the the Langmuir model.
