EPA 1664C Oil and Grease SGT Extractable Test in Water
The EPA Method 1664C is a critical analytical technique used to quantify the concentration of oil and grease that can be extracted from water samples using a solvent-based procedure. This method employs Supercritical Fluid Extraction Technology (SGT) for the extraction, followed by gas chromatography with flame ionization detection (GC-FID). The EPA 1664C test is particularly relevant in sectors dealing with industrial effluents and wastewater treatment.
The SGT process uses carbon dioxide as a solvent at high pressure and temperature to extract oil and grease components from water. This approach ensures that the extracted compounds are representative of those present in the original sample, thus providing accurate results for regulatory compliance purposes. The use of GC-FID allows for precise measurement of the extracted hydrocarbons.
The EPA 1664C test is widely used by industries such as petrochemicals, oil refining, and wastewater treatment plants to monitor discharge limits set under environmental regulations. Compliance with these standards is crucial for preventing contamination of water bodies and ensuring public health and safety.
Preparation of the sample involves the collection of a representative water sample, which is then filtered through a 0.45 µm filter before extraction. The extracted oil and grease are analyzed using GC-FID to determine their concentration in parts per million (ppm).
The precision and accuracy of this method make it an essential tool for environmental monitoring and compliance. It helps in identifying potential sources of contamination, thereby enabling proactive measures to mitigate pollution.
| Key Parameters | Values |
|---|---|
| Extraction Solvent | Carbon Dioxide (CO2) |
| Temperature | 31.1°C ± 0.5°C |
| Pressure | 74 atm ± 0.5 atm |
| Detection Method | Gas Chromatography with Flame Ionization Detector (GC-FID) |
The EPA 1664C test is designed to extract and quantify total petroleum hydrocarbons (TPH), which include aliphatic, aromatic, and cyclic compounds. This comprehensive approach ensures a thorough assessment of the oil and grease content in water samples.
Compliance with EPA regulations on oil and grease discharge limits is essential for maintaining clean water ecosystems. The results from this test can inform corrective actions to reduce contamination sources, ensuring that wastewater meets stringent regulatory requirements.
The process involves multiple steps: sample collection, filtration, extraction using SGT, and finally, analysis by GC-FID. Each step is critical in ensuring the integrity of the final analytical result.
By leveraging EPA 1664C, industries can effectively manage their environmental impact and ensure compliance with local and national regulations. This method provides a robust framework for assessing oil and grease levels in water samples, contributing to sustainable practices in industrial operations.
