Abstract

The objective of this study was to clarify the possibility of adsorption trichloroethylene (TCE) of pretreated granular activated carbon (GAC). The chemical solution used for the acidic treatment was phosphoric acid. In addition, the effect of ultrasound on GAC assessed in this experiments. It was observed that the adsorption of TCE were different based on pH value of pretreated GAC. However, natural water such as groundwater has various factors like ionic strength and hardness etc. Therefore, more laboratory work is needed to study about pretreated GAC.
