Application

TCE may be used as a metal cleaning or degreasing agent.
Tetrachloroethylene (TCE) was employed as solvent to investigate the NMR spectra of end functionalized cyclopentadienyl poly(ethylene) (PE-Cp).

General description

Tetrachloroethylene is a chlorinated ethene derivative mainly found in the contaminated groundwater due to its extensive use as a dry cleaning solvent. Its sorption and reduction kinetics with zero-valent iron has been determined in a closed, anaerobic batch system.
Tetrachloroethylene, a chlorinated ethylene, is a common industrial solvent. It is also one of the major contaminant found in groundwater supplies.

Bioelectrochemical systems (BESs) are regarded as a promising approach for the enhanced dechlorination of chlorinated aliphatic hydrocarbons (CAHs). However, the electron distribution and transfer considering dechlorination, methanogenesis, and other bioprocesses in these systems are little understood. This study investigated the
