Adsorption Kinetics of Chloroform from Aqueous Solutions onto Activated Lignite

Abstract: The lignite coal researched by this study was subjected to a two-stage activation process performed in the scope of obtaining active carbon from domestic resources. ''Activation'' and ''carbonization'' stages were used in the experiments. The modified lignite was produced by impregnating lignite with KOH and washing the activation product with 15% HCl solution after thermal treatment. Increasing KOH dosage also increased the removal efficiency. The variables investigated in adsorption experiments were contact … Show more

“…Starting from a concentration of pollutants equal to 20 mg/L and at pH 6 and 25 • C, 0.5 g/L of adsorbent was able to remove 93.9% of the compound after 60 min, till the complete adsorption within 90 min. Tongur and Aydin [49] eliminated chloroform from drinking water through adsorption onto activated lignite. To find the optimal operative conditions, they investigated different values of activation and carbonization time during the production of the adsorbent: in 180 min and 120 min, respectively, they removed 99.5% of the initial pollutant.…”
