Determination of Tetrachloroethene and Trichloroethene in Water: Monitoring of Volatile Organic Pollutants

Why Determination of Tetrachloroethene and Trichloroethene?

What are Tetrachloroethene and Trichloroethene?

Tetrachloroethene (PERC): It is a colorless, volatile, chlorinated organic solvent widely used in industrial solvents. Uses include textile cleaning, metal cleaning and as a thinning component of solvent-based paints. It can cause groundwater and surface water pollution.
Trichloroethane (TCA): Used as a colorless, chlorinated, volatile solvent. It is used as a solvent in paints, varnishes and inks. It can cause environmental health problems by causing water pollution.

Methods for the Determination of Tetrachloroethene and Trichloroethane in Water

Gas Chromatography (GC): Tetrachloroethene and trichloroethene in water are passed into the gas phase of the sample with an initiator chemical. Gives precise and accurate results. Can detect even low concentrations.
Initiated Desorption (Solid Phase Microextraction - SPME): Tetrachloroethene and trichloroethene in water are adsorbed with SPME fiber and then analyzed in gas chromatography.
Liquid-Liquid Extraction (LLE): Tetrachloroethene and trichloroethene in water are extracted using an organic solvent and then analyzed by gas chromatography. Effective for heavy contaminants.
Headspace Gas Chromatography (HS-GC): Tetrachloroethene and trichloroethene in the vapor phase in water are measured by gas chromatography. Simplifies the sample preparation process. Offers high sensitivity in separation of compounds.

Why Determination of Tetrachloroethene and Trichloroethane is Necessary?

Environmental Impact: When these chemicals enter water supplies, they can be toxic to humans and other living organisms.
Water Safety: The presence of these contaminants in water treatment plants can affect the effectiveness of treatment processes and thus pose a drinking water safety risk.
Environmental Protection: Monitoring of organic solvents such as tetrachloroethene and trichloroethene is critical for water to be free of contaminants.

Tetrachloroethene and trichloroethene are important contaminants to monitor in environmental water supplies. Accurate and sensitive determination of these compounds in water is critical for water safety and environmental protection. Advanced gas chromatography methods are best suited for the detection of these compounds. Regular analysis is recommended to ensure and protect environmental water quality.
