Embodiment Construction

[0023] A detailed description of the specific implementation of the present invention is given below.

[0024] The detection method of the inductively coupled plasma atomic emission spectrometry of the present invention for measuring the migration amount of harmful elements in plastic packaging containers for food includes the following steps:

[0025] 1. Sample preparation method

[0026] 1. Migration test

[0027] According to the expected use and use conditions of the sample to be tested, in accordance with the migration test method and test conditions specified in GB / T 23296.1-2009, add appropriate food simulants to the container to be tested to 4 / 5 volume for migration test. After thoroughly mixing, take part of the food simulant test solution for analysis.

[0028] 2. Treatment of food simulant test solution

[0029] 2.1 Water simulant test solution or acetic acid simulant test solution can be directly measured.

[0030] 2.2 Ethanol simulant test solution

[0031] Pipette 10.00mL et...

Abstract

The invention relates to a detection method of harmful element migrated masses in a plastic packaging container for foods, in particular to a detection method for simultaneously measuring migrated masses of lead, cadmium, chromium, arsenic, antimony and germanium in a plastic packaging container for foods by an ICP-AES (inductively coupled plasma emission spectrometry) method. The detection method comprises the following steps: 1, carrying out a migration test; 2, carrying out a blank test; and 3, carrying out measurement by an inductively coupled plasma emission spectrometer. The ways of RF (radio frequency) power amplification (for a 3% acetic acid simulacrum test solution), ethanol removal (for a 10% ethanol simulacrum test solution) and microwave digestion (for a delicate olive oil test solution) are used to efficiently, simply and quickly measure the migrated masses of various harmful elements in four simulacrums in the plastic packaging container for the foods simultaneously.

Description

Technical field [0001] The invention relates to a method for detecting the migration of harmful elements in plastic packaging containers for food, and in particular to a method for simultaneously determining lead, cadmium, chromium, and chromium in plastic packaging containers for food using inductively coupled plasma atomic emission spectrometry (ICP-AES method) Detection of migration of arsenic, antimony and germanium in four food simulants. Background technique [0002] Plastic is a kind of high molecular material made of high molecular polymer-resin as the basic component, and adding some various additives to improve its performance. Plastics used for food containers include polyethylene (PE), polypropylene (PP), polystyrene (PS), polycarbonate (PS), polyethylene terephthalate (PET), melamine formaldehyde resin ( Melamine resin MF) and so on. According to different uses and processing requirements, plastics should be added with toxic stabilizers such as lead compounds, cadm...
