Abstract
The present invention provides a kind of detection method for effectively measuring perfluoro caprylic acid content in plastics and textile.This method is that Soxhlet extractor extracts sample, is settled to 10mL with methane and is analyzed and tested, tested perfluoro caprylic acid is fully extracted, and substantially increases the accuracy of test result.
Description
Technical field
The present invention relates to a kind of detection method of perfluoro caprylic acid content in effectively measurement plastics and textile, belong to plastics and
Poisonous and harmful substance detection technique field in textile.
Background technique
Perfluoro caprylic acid, is abbreviated as PFOA, one of perfluorochemical organic acid, is white crystal under room temperature, main to use
Make surfactant, emulsifier.PFOA is difficult to degrade from environment, it is possible to enter human body by food, air and water.It may
Lead to fertility-rate decline and other disease of immune system.On October 27th, 2017, World Health Organization's international cancer research aircraft
The carcinogenic substance inventory edit reference that structure is announced, PFOA is in 2B class carcinogenic substance inventory.
PFOA is not easy to be degraded after entering atmospheric environment, and can be migrated or be transported at a distance, reaches ground with dried wet deposition,
Or enter water body or soil.Zoopery has shown PFOA to animal pest.PFOA can pass through intake, sucking, skin contact etc.
It is absorbed by the body, causes peroxisome breeding in human body to influence energy transmission, destruction cell membrane etc., to induce cancer, liver
The diseases such as enlargement.
Content for whether there is PFOA and PFOA in plastics and textile is how many, needs a kind of convenience, effectively inspection
Survey method detects.
Summary of the invention
For the content of PFOA in plastics and textile, the present invention provides one kind can effectively quantitative detection plastics and weaving
The method of PFOA content in product.
The present invention includes a kind of effective ways that PFOA content in plastics and textile is tested using Soxhlet extractor.
Detailed description of the invention
Attached drawing 1 is the operational flowchart of the embodiment of the present invention.
Specific embodiment
Below with reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.Those skilled in the art can understand easily advantages of the present invention and effect by the revealed content of specification.This
Invention can also be embodied or practiced by other different specific examples, and the various details in this specification also can be based on difference
Viewpoint and application.
The operational flowchart of the embodiment of the present invention is as shown in Fig. 1, takes 10cm × 10cm sample at room temperature, by sample
Product are cut into 5mm × 5mm, and are uniformly mixed (if the article of analysis is finished product, the various pieces of sample want proportion sample).
The running parameter of Soxhlet extractor is set, while carrying out blank assay at identical conditions.The sample handled well is placed on
In 150mL Soxhlet extractor paper tube, absorbent cotton is placed on upper layer, 80mL methanol, 70 ± 0.2 DEG C of extraction 1h, to make sample are added
Potential PFOA is sufficiently released in product.It is concentrated, is settled in 10mL volumetric flask after cooling, test solution passes through 0.22 μm of PTFE
It is transferred in sample injection bottle after filter membrane filtering.Preparing standard solution series, after establishing standard curve, is analyzed using LC-MS
Blank, sample solution are measured, quantitative analysis is carried out by content of the standard curve to PFOA in sample.
Above-described embodiment is merely illustrative the principle of the present invention and effect, and is not intended to limit the present invention.It is any
Those skilled in the art can reasonably modify above-mentioned implementation under the premise of without prejudice to spirit of that invention and scope
With variation.Therefore, all authority protection scope of the invention, should be using the range of claims as foundation.
Claims (2)
1. the detection method of perfluoro caprylic acid content in a kind of effectively measurement plastics and textile, it is characterised in that use Soxhlet extraction
Method tests the content of PFOA in plastics and textile.
2. the detection method of PFOA in a kind of effectively measurement plastics according to claim 1 and textile, it is characterised in that
Using Soxhlet extractor, the sample handled well is placed in 150mL Soxhlet extractor paper tube, absorbent cotton is placed on upper layer, is added
80mL methanol, 70 ± 0.2 DEG C of extraction 1h, so that potential PFOA in sample be made sufficiently to release.It is concentrated, is settled to after cooling
In 10mL volumetric flask, test solution is transferred in sample injection bottle after 0.22 μM of PTFE filter membrane filters and is analyzed using LC-MS.With
Reach efficient, accurate analysis.
