Method for simultaneously extracting and enriching four typical odor substances and three algal toxins in quantitative water

The invention discloses a method for simultaneously extracting and enriching four typical odor substances and three algal toxins in quantitative water, belongs to the technical field of extraction of pollutants, and aims to solve the technical problems that an existing method is poor in repeatability and high in organic solvent consumption, emulsification is generated in the extracting process, and enriching and extracting cannot be simultaneously performed. The method includes the steps: firstly, performing pumping and filtering on target water samples, and adjusting the target water samples to acidity; secondly, activating and cleaning solid-phase extraction columns; thirdly, spraying and eluting the odor substances; fourthly, spraying and eluting the algal toxins; fifthly, concentrating the odor substances and the algal toxins. According to the method, the consumption of the organic solvents is reduced, emulsification is omitted in the treating process, and the method is short in use time and high in effic
