Özet
The ability of brown coals (leonardites) to remove chromium(VI) from aqueous solutions was studied as a function of pH, contact time, adsorbent nature, and concentration of metal solutions. The adsorption of Cr(VI) was higher between pH 2.0 and 3.0 for all brown coals and maximum sorption was observed at pH 3.0. The Langmuir adsorption isotherm was used to describe observed sorption phenomena, and the constants were evaluated. The maximum adsorption capacity of 0.92 mmol of Cr(VI)/g for YK, 0.98 mmol of Cr(VI)/g for KK was found from experimental data. KK was the best among the selected adsorbents for the sorption of Cr(VI) at pH 3 and the sorption was 81% out of 100 ppm Cr(VI) after 120 min of stirring.
