Abstract

The invention discloses a method for determining a transfer volume of aromatic amine in paper and a paperboard. The method comprises the following steps: taking the modified polyphenyl ether as a simulant, conducting solvent extraction on the simulant, concentrating the extract liquor, and carrying out the GC / MS method to determine the transfer volume. The steps and the method provided by the invention can be effectively used for determining the transfer volume of the specific aromatic amine which is transferred from the paper and the paperboard to the dry food simulant; the method is feasible, simple to operate, accurate in method, high in sensitivity, and of value for popularization and application.

Description

technical field [0001] The invention relates to a method for measuring the migration of specific aromatic amines in paper and cardboard, specifically involving the use of improved polyphenylene ether (MPPO, Tenax) as a simulant, the simulant is extracted with a solvent, and the extract is concentrated and then subjected to gas chromatography-mass spectrometry Determination of migrating aromatic amines by GC / MS. Background technique [0002] As an important class of packaging materials, paper packaging materials are widely used, and these packaging papers are usually printed with patterns or characters, and it is possible to use coatings containing azo dyes. Some azo dyes will decompose and release aromatic amines under certain conditions. Many aromatic amines are harmful to human health and the environment, especially 2,4-dimethylaniline, 2-naphthylamine, p-chloroaniline, benzidine, 4- Aminobiphenyl, etc. are carcinogens. When paper packaging materials are in direct contac...
