Embodiment 1

[0021] Dissolve 4g of sodium hydroxide in deionized water, immerse 2g of PE film in the sodium hydroxide solution, then put it into an ultrasonic reactor, control the temperature at 60°C for 8 hours, take out the PE film after the reaction, and wash it with deionized water Clean; add 25g of lignin iron into deionized water, immerse the cleaned PE film in the lignin iron solution, and react at a temperature of 50°C for 6 hours. After the reaction, take out the PE film, dry at 90°C to constant weight, and Rinse with water and dry at room temperature. After the dried PE film was sampled and digested, the total iron content in the reaction product was measured by inductively coupled plasma atomic emission spectrometry to be 50.7mg / g film, and the breaking force was 2.1N. The infrared spectrum of the reaction product is as figure 1 As shown, there is a significant change compared with the infrared spectrum of PE film, 2916cm -1 、2848cm -1 、1471cm -1 、717cm -1 The absorption pe...

Embodiment 2

[0023] Dissolve 4g of sodium hydroxide in deionized water, immerse 2g of PE film in the sodium hydroxide solution, then put it into an ultrasonic reactor, control the temperature at 70°C for 12 hours, take out the PE film after the reaction, and wash it with deionized water Clean; add 100g of lignin iron into deionized water, immerse the cleaned PE film in the lignin iron solution, and react at a temperature of 80°C for 10 hours. After the reaction, take out the PE film, dry at 110°C to constant weight, Rinse with water and dry at room temperature. After the dried PE film was sampled and digested, the total iron content in the reaction product was measured by inductively coupled plasma atomic emission spectrometry to be 759.6mg / g film, and the breaking force was 1.7N. The change situation of reaction product infrared spectrum is identical with embodiment 1.

Abstract

The invention discloses a PE film material containing lignin iron, and belongs to the technical field of functional polymer materials. According to the invention, a PE film is used as a material basicskeleton, and the PE film reacts with lignin iron, so that the lignin iron is grafted on the surface of the PE film, and a novel PE film material containing the lignin iron is obtained; the synthesismethod is simple in process, mild in reaction condition, free of high-pressure or high-temperature reaction, easy to control and capable of easily achieving large-scale production of materials, adopted chemical reagents are non-toxic or low-toxicity reagents, no toxic by-product is generated in the reaction process, and the method is environmentally friendly; when the PE film material is appliedto remediation of arsenic-contaminated soil, the pH value of the soil cannot be changed, and the convenient recovery performance of the iron-containing material is superior to that of an existing iron-containing material; and the PE film material not only has good mechanical properties, but also effectively improves the aerobic biodegradability of the basic framework material PE film.

Description

technical field [0001] The invention relates to a PE film material and a synthesis method thereof, in particular to a PE film material containing lignin iron and a synthesis method thereof, belonging to the technical field of polymer materials. Background technique [0002] Iron-containing materials are recognized as an ideal material for remediating arsenic-contaminated soils, with the advantages of high remediation efficiency and low cost. At present, the iron-containing materials used for arsenic-contaminated soil remediation are as follows: [0003] (1) Iron (hydroxide) oxide or iron salt or zero-valent iron (iron powder). Hu Liqiong et al. (Journal of Environmental Engineering, 2014, 8(4): 13-18) used FeCl 3 , FeCl 2 , Fe 2 o 3 , FeO significantly reduced the content of soluble arsenic and toxic leached arsenic in arsenic-polluted paddy soil; CN106001096A reported ferrate and divalent, ferric salt or zero-valent iron, adding precipitant to co-precipitate arsenic in...
