REMOVAL OF Cr(VI) FROM AQUEOUS SOLUTION BY ACTIVATED COAL FROM LIGNITE COAL
Activated coal produced from Ağaçlı Lignite coal was used to remove Cr(VI) from aqueous solutions. The adsorption of Cr(VI) was studied as a function of initial concentration, time, pH, adsorbent concentration and temperature. The adsorption data were found to fit to Langmuir and Freundlich isothe...

| Summary: | Activated coal produced from Ağaçlı Lignite coal was used to remove Cr(VI) from aqueous solutions. The adsorption of Cr(VI) was studied as a function of initial concentration, time, pH, adsorbent concentration and temperature. The adsorption data were found to fit to Langmuir and Freundlich isotherms. Lagergren equation was used to calculate the adsorption rate. The amount of Cr(VI) adsorbed was increased with decreasing pH and decreased with increasing temperature. |
