GB/T 33285.2-2024 Leather and fur—Determination of alkylphenols and ethoxylated alkylphenols—Part 2:Indirect method
Basic Information
Scope
This document describes the experimental methods for determining alkylphenols (nonylphenol and octylphenol) and alkylphenol polyethylene glycol ethers (nonylphenol polyethylene glycol ether and octylphenol polyethylene glycol ether) in leather and fur using high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GCMS). This document is applicable to the determination of alkylphenols and alkylphenol polyethylene glycol ethers in leather, fur, and their products. It is also applicable to the determination of alkylphenols and alkylphenol polyethylene glycol ethers in leather and fur processing aids. Note: The methods specified in this document (indirect method) use different extraction solvents from those used in the direct method, so the test results of the two methods may have similar trends, but they are not absolutely identical.
