| titleOfInvention | Method for rapidly detecting trace halogenated biphenyl in water body |
| abstract | The invention discloses a method for rapidly detecting trace halogenated biphenyl in a water body, which comprises the following steps: dissolving sulfonated polystyrene-N-vinyl pyrrolidone copolymer in N-N dimethylformamide, and adding Fe 3 O 4 Performing ultrasonic oscillation on the powder to obtain a magnetic composite adsorbent; dispersing the magnetic composite adsorbent in a water body to be detected, magnetically attracting the magnetic composite adsorbent dispersed in the water body to be detected to the inner side wall surface of the container adjacent to the permanent magnet by using the permanent magnet, discarding the supernatant, ultrasonically eluting the magnetic composite adsorbent by using an organic solvent, drying the magnetic composite adsorbent by using nitrogen, and redissolving to obtain a detection sample; the detection sample is detected by GC-MS. The detection method can effectively enrich the halogenated biphenyl in the water body by utilizing the magnetic composite adsorbent, and the adsorbent enriched with trace halogenated biphenyl can be quickly separated from the water body, and the quick detection of the trace halogenated biphenyl in the water body is realized by combining the GC-MS technology. |
