| titleOfInvention | A method of perfluorooctane sulfonate and the own sulfonic acid of perfluor in measurement crop edible part |
| abstract | The invention belongs to pollution determination technical fields, disclose a kind of method for measuring perfluorooctane sulfonate and the own sulfonic acid of perfluor in crop edible part, key step are as follows: sample will be used as after the freezing of crop edible part, dry, crushing, internal standard compound is added into sample to mix, then dissociation agent is added and carries out dissociation reaction, tetrabutyl hydrogen sulfate ammonia and sodium carbonate buffer are added, methyl tertiary butyl ether(MTBE) is added after mixing well and carries out ultrasonic extraction, obtains extraction matter；Matter is extracted after the WAX pillar Solid phase extraction equipped with graphitic carbon black, obtains sample detection liquid, then sample detection liquid is measured using HPLC-MS-MS method.The method of the invention rate of recovery is high, precision is good, high sensitivity, and anti-complex matrices interfere, at the same suitable for cereals, root vegetables, leaf vegetables, fruit vegetables perfluorooctane sulfonate and the own sulfonic acid of perfluor measurement. |
