ASTM D7678 Petroleum Ether Hydrocarbons Test in Water
The ASTM D7678 test method is designed to determine the concentration of petroleum ether hydrocarbons in water samples. This is a critical analysis for environmental monitoring, especially in sectors such as wastewater treatment and industrial discharge. The test measures total petroleum-like organic matter (TPOM) present at a specific temperature, which can help identify sources of contamination and ensure regulatory compliance.
The procedure involves extracting hydrocarbons from the water sample using petroleum ether under controlled conditions. After extraction, the solvent is evaporated, leaving behind only the petroleum-like compounds. The weight of this residue directly correlates to the concentration of TPOM in the original water sample. This test method is particularly useful for assessing the effectiveness of treatment processes and monitoring environmental impacts.
The ASTM D7678 test is applicable to a wide range of water types, including surface waters, groundwaters, and wastewater from various industries such as petrochemicals, refining, and manufacturing. The test helps in identifying hydrocarbon pollution sources that could impact aquatic ecosystems or human health.
The testing process typically starts with the collection of a representative water sample. Once collected, the samples are brought to our laboratory for analysis. Our team follows the ASTM D7678 procedure meticulously, ensuring accurate and reliable results. The precision and accuracy of this test depend significantly on the quality of the sample prep and adherence to the standard method.
The acceptance criteria for ASTM D7678 are based on the recovery rates and repeatability checks. A successful test will show consistent recoveries across multiple samples, indicating that the extraction process is effective. The results are reported in milligrams per liter (mg/L) of TPOM. These values can be used to assess compliance with environmental regulations or to evaluate the performance of wastewater treatment facilities.
| Application | Description |
