1 Scope

This standard specifies the method for the determination of alkylphenol in rubber shoes and rubber shoes by gas chromatography-mass spectrometry. This standard applies to rubber shoes and rubber shoes in the determination of alkylphenol (octylphenol and nonylphenol) content.

2 method principle

The octylphenol and nonylphenol in the sample were extracted by ultrasonic with methanol, determined by gas chromatography-mass spectrometry (GC-MS) Ionic confirmation, external standard method.
