| titleOfInvention | Test method for textile poisoning |
| abstract | The invention discloses a method for detecting toxaphene for textiles. The pretreatment steps include: mixing a sample with a first specified amount of extractant, and performing ultrasonic treatment at a first specified temperature for a first specified time; The first filtrate is obtained by the second filtration, the first filter residue is mixed with the second specified amount of extractant, and the ultrasonic treatment is carried out at the first specified temperature for the second specified time; the second filtration is performed, and the second filtrate and all The first filtrate is mixed for dehydration and concentration treatment; the test substance after dehydration and concentration treatment is settled to a specified volume with n-hexane, centrifugation or the third filtration is performed, and the liquid phase of the centrifugation or the third filtration or To be tested. The invention adopts gas chromatography negative chemical ionization source mass spectrometer to detect toxaphene, which not only has higher sensitivity, the detection limit can reach 0.05 μg/g to meet stricter detection requirements, and also has good anti-interference due to selective ion monitoring. ability to improve test efficiency. |
