Abstract
The invention discloses a gas chromatograph method for detecting phthalate ester (PAEs) pollutants in plastic. The method comprises the following steps: cutting an external packing material, weighing about 0.5 gram of external packing material, placing the external packing material in a conical flask (100 mL), adding 100 mL of n-butane extracting agent, soaking the conical flask in a thermostatic water bath with a temperature of 60 to 80 DEG C for 30 to 60 minutes, carrying out extraction, filtering the extract, blowing the filtrate by nitrogen to concentrate the filtrate, diluting the filtrate to a constant volume, then carrying out gas chromatography. A proper amount of anhydrous sodium sulfate or anhydrous ethanol is added to remove water. To prevent the surface of glassware from being contaminated, all glassware for the experiment is washed by ultrasonic waves. The provided gas chromatograph method has the advantages that the extraction and analysis conditions of plastic package PAEs content measurement are optimized, and the method can satisfy the requirements of daily detection of basic labs.
Description
Technical field
The present invention relates to Material Field, the Gas Chromatographic Method of phthalate pollutant in a kind of plastics.
Background technology
Phthalic acid ester (phthalate ester) compound (PAEs) is a kind of plasticizer for plastic cement products, it is intended that increase product pliability, therefore to produce flexible PVC product be the most necessary a kind of raw material.Owing to its addition is not greatly and with covalent bond form and resin-bonded, under proper condition, constantly can discharge to surrounding, cause and soil, water body, food etc. are polluted widely, and invade human body by biological concentration and food chain, cause potential hazard.
Summary of the invention
It is an object of the invention to provide the Gas Chromatographic Method of phthalate pollutant in a kind of plastics.
The technical scheme is that and be achieved in that: the Gas Chromatographic Method of phthalate pollutant in plastics, about 0.5 g is weighed in 100 ml conical flasks after being shredded by its housing material, add 100 ml normal butane extractants, after 60-80 DEG C of constant water bath box soaks 30-60 minute, extract, extracting solution filters, and then blows concentration constant volume with nitrogen, then carries out gas chromatographic analysis.Add appropriate anhydrous sodium sulfate or dehydrated alcohol except water.For avoiding the pollution on glass drying oven surface, ultrasonic waves for cleaning all used by total Test glass drying oven.
The invention has the beneficial effects as follows: the present invention uses the content of the PAEs measured in plastics package, inquired into the condition optimizing in terms of extraction, analysis, to meet the demand of laboratories routine testing work.
Detailed description of the invention
The Gas Chromatographic Method of phthalate pollutant in plastics, about 0.5 g is weighed in 100 ml conical flasks after being shredded by its housing material, add 100 ml normal butane extractants, after 60-80 DEG C of constant water bath box soaks 30-60 minute, extract, extracting solution filters, and then blows concentration constant volume with nitrogen, then carries out gas chromatographic analysis.Add appropriate anhydrous sodium sulfate or dehydrated alcohol except water.For avoiding the pollution on glass drying oven surface, ultrasonic waves for cleaning all used by total Test glass drying oven.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope of present disclosure; according to technical scheme and inventive concept equivalent or change in addition thereof, all should contain within protection scope of the present invention.
