| titleOfInvention | Method for evaluating concentration of perfluoroalkyl acid precursor in water body |
| abstract | The invention discloses a method for evaluating the concentration of a precursor of perfluoroalkyl acid in a water body, which comprises the steps of carrying out plasma conversion treatment on the water body to be evaluated by adopting a gas-liquid equal-phase discharge plasma generator; measuring the concentration of perfluoroalkyl carboxylic acid in the water body before and after the plasma conversion treatment; and then evaluating the concentration of the precursor of the perfluoroalkyl acid in the water body to be detected. The method can evaluate the total concentration of the perfluoroalkyl acid in various water bodies such as sewage, rainwater, surface water, underground water, rivers, lakes and the like, and the method adopts the plasma method to treat the perfluoroalkyl acid precursor, has higher generation rate of converting the perfluoroalkyl acid precursor into PFCAs, high conversion efficiency of the precursor and more accurate measurement result. |
