Determination of Acrylonitrile: Precise and Accurate Analysis Methods

Why is Acrylonitrile Determination Important?

What is Acrylonitrile?

Acrylonitrile is a colorless, volatile organic chemical compound that is commonly used as a raw material in the production of plastics, fibers and other synthetic materials. It is also an important component in the production of some chemical reagents. Acrylonitrile can be released into the environment during industrial processes and can be found in environmental media such as air, water and soil. This compound, which is toxic to human health, can cause harmful effects in both acute and chronic exposures, especially adverse effects on the nervous system and lungs.

Why is Acrylonitrile Determination Important?

The determination of acrylonitrile is of great importance for determining the concentration of this compound in environmental and workplace conditions. In both industrial and environmental settings, determining the presence of toxic compounds such as acrylonitrile is essential to control the release of this compound and minimize potential health risks. Exposure to acrylonitrile can cause chronic health problems, genotoxicity and cancer. Therefore, the accurate and sensitive determination of acrylonitrile is a critical step in protecting human health and complying with environmental regulations.

Methods and Analysis Process

The determination of acrylonitrile is usually done using techniques such as gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Here are the details of these analysis methods:

1. Air or Water Sampling: For the determination of acrylonitrile, gas-phase sampling is usually performed. This involves taking the concentration of acrylonitrile from air or water samples. Using active or passive sampling methods, it is determined how this compound is dispersed and concentrated in this environment.
2. Collection of Samples: Air sampling is usually done with tubes or devices containing activators. Sampling is carried out with the help of a pump or with passive samplers based on atmospheric pressure. For water samples, acrylonitrile is determined by passing the water into the gas phase. This is usually done by headspace sampling or evaporation of acrylonitrile from the water sample.
3. Extraction and Cleaning: The collected samples are usually extracted using solvents. Acrylonitrile is soluble in organic solvents and purified by extraction from these solvents. Cleaning processes are applied to rid the extracted sample of unwanted components. This ensures high purity analysis.
4. Gas Chromatography / Mass Spectrometry (GC/MS): The extracted acrylonitrile is separated by gas chromatography and then the structure is confirmed by mass spectrometry. GC-MS provides accurate identification and quantitative analysis of acrylonitrile. Mass spectrometry provides confirmation of the chemical structures and concentrations in the sample.
5. Calibration and Quality Control: Analysis processes are validated using calibration standards and quality control materials. This ensures reliability of results and accurate analysis.

Related Regulations and Standards

The determination of acrylonitrile is carried out in many countries in accordance with environmental regulations and occupational safety rules. In Turkey, Ministry of Environment and Urbanization regulations such as the “Water Pollution Control Regulation” and the “Workplace Air Quality Regulation” require monitoring of toxic compounds such as acrylonitrile. At the international level, OSHA (American Occupational Safety and Health Administration) and EU REACH (Registration, Evaluation, Authorization and Restriction) regulations mandate the monitoring and safe use of chemicals such as acrylonitrile.
