In these studies, a typical lignite coal found near Istanbul (Yeniköy) and its activated products were used to adsorb TCA from aqueous solutions. Particle sizes of coal samples and the concentrations of TCA solutions were chosen as parameters against the fixed amount of adsorbent. The maximum efficiency has been obtained for the coal having (-120 + 150) mesh size fraction activated by heating. As a result, it was shown that these kinds of lignite coals could be used as a good adsorbent. In addition, it was also proved that both the removal and recovery of TCA from some waste waters would easily be possible.
