| titleOfInvention | Method for measuring PPCPs in environmental soil |
| abstract | The invention relates to a method for determining PPCPs in an environmental soil sample, which comprises the steps of sample extraction, enrichment purification, separation purification and analysis detection, wherein the step of sample extraction further comprises the step of adding N isotope internal standard extracting solutions, wherein N is an integer more than 1 and less than or equal to 16, preferably 4-16, and more preferably 8-15. The invention relates to the field of PPCPs detection, in particular to a method for determining the content of 16 PPCPs in soil and sediment samples. According to the invention, the original analysis method is improved, the multi-isotope internal standard analysis method is established, most target objects have corresponding isotope markers as internal standards, corresponding target objects which cannot purchase the isotope markers are realized, and the isotope markers of substances with similar structures and properties are selected as the internal standards. And establishing an analysis method of the multi-isotope internal standard with higher sensitivity, lower detection limit and stronger stability. |
