Method for detecting hydrocarbons in water |
| abstract |
The presence of hydrocarbons in water is detected by contacting a water sample with an adsorbent material to extract hydrocarbons from the water sample and then contacting the adsorbent material with a solvent for the hydrocarbons. A developer such as a miscible nonsolvent liquid is mixed into the solvent to produce a test mixture. The turbidity of the test mixture is observed to determine the presence of hydrocarbons in the water sample. The nonsolvent may contain at least 0.5% salt, e.g., at least 1%, preferably 5% salt, and an emulsifier. Turbidity may be measured quantitatively by measuring light scattered at 90 DEG to a test light beam or by visual comparison to a reference scale. |
