Abstract
Tetrachloroethylene (TCE) is a chlorinated aliphatic hydrocarbon, used in many industries. Effective and efficient treatment of industrial
wastewater, containing TCE, is one of the environmental requirements. The purpose of this study was to determine the role
of alkaline environments in TCE removal rate from aqueous solutions, using copper-doped pumice. This experimental study was
performed, using granulated pumice stones with a mesh 4 (8.4 mm) in alkaline conditions; the samples were coated with copper.
Copper-doped pumice was prepared as a bed at doses of 1, 2, and 3 g/L; the study was performed at pH ranges of 3, 7, and 11. Based
on the results, copper-doped pumice showed good efficacy in TCE removal; in addition, its performance increased in alkaline conditions.
Therefore, use of this stone for the treatment of wastewater, containing TCE, is effective due to its availability and low cost.
Besides, it can be considered a good option, given its high efficiency in the absorption process.
