Abstract

The invention discloses a kind of application of waste and old agricultural polyethylene mulch in absorption hydrophobic organic pollutant, the hydrophobic organic pollutant is phthalate compound or brominated flame-retardant.Present invention materials are waste and old agricultural mulching, develop the new application of agricultural mulching, environmental protection and economy, and have higher adsorption efficiency than Plain PE film.

Description

A kind of application of waste and old agricultural polyethylene mulch in absorption hydrophobic organic pollutant
One, technical field
The present invention relates to a kind of application of waste and old agricultural polyethylene mulch in absorption hydrophobic organic pollutant.
Two, background technique
Agricultural mulching is introduced since late 1970s China, with the development of agricultural, mulch is more and more extensive Ground is applied in agricultural production, its application is greatly promoted the raising of farm output and benefit.Currently, China is in the world Agricultural mulching production and the most country of usage amount.Plastic film mulching cultivation area in 2014 is just more than 0.25 hundred million hm2, mulch year 142.8 ten thousand t of sales volume.
Common agricultural mulching is using polyethylene, polyvinyl chloride as primary raw material, by adding antioxidant, ultraviolet radiation absorption Organic compound material made of agent etc. has good translucency and mechanical ductility.Its molecular structure is highly stable, is difficult Light degradation and thermal degradation are carried out under natural conditions, also not easily pass through the degradation of the biological modes such as bacterium and enzyme, under normal circumstances, residual film It can retain in the soil 200~400 years.
But while agricultural mulching is widely used, the fragment remained in arable soil has become China's farming One of main pollution problem in area.The Chinese Academy of Agricultural Sciences's monitoring data show, at present the farmland of the long-term overlay film in China, every 667m2 Mulch residual quantity is in 5~15kg in farmland.Remaining mulch amount is accumulated year by year in farming land, caused by pollute and be on the rise. Used plastic collection is the very wise move prevented and remedied pollution, but due to China's mulch thickness ultrathin, recovery efficiency is low the problems such as, give recycling and reusing It has caused great difficulties.And recycling and reusing inefficiencies, secondary use approach are also less.
Three, summary of the invention
In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a kind of waste and old agricultural mulchings dredges in absorption Application in aqueous organic pollutant.
The technical solution adopted by the invention is as follows:
A kind of application of waste and old agricultural polyethylene mulch in absorption hydrophobic organic pollutant, the hydrophobicity are organic Pollutant is phthalate compound or brominated flame-retardant.
Further, the phthalate compound is preferably DBP (dibutyl phthalate), BBP (adjacent benzene Diformazan acid butyl benzyl ester) or DEHP (phthalic acid (2- ethylhexyl) diester).
Further, the phthalate compound is most preferably DBP (dibutyl phthalate).
Further, the brominated flame-retardant is preferably hexabromocyclododecane.
Further, the application are as follows: clean up waste and old agricultural polyethylene mulch with clear water, successively in methylene chloride With impregnated for 24 hours respectively in methanol, then cleaned up with ultrapure water, and dry and then fixed by copper wire, it is organic to be placed in hydrophobicity It is adsorbed in pollutant, the concentration of the hydrophobic organic pollutant is 0.1~10mg/L.
Further, 30~45 DEG C of the drying temperature.
Compared with prior art, the beneficial effects of the present invention are: draw materials as waste and old agricultural mulching, develop agricultural mulching New application, environmental protection and economy, and than Plain PE film have higher adsorption efficiency.

Five, specific embodiment
Below by specific embodiment, the present invention is described further:
Embodiment 1
Phthalate (PAEs) in adsorption aqueous solution.
(1) copper wire of one section of 10cm of clip cuts an agreement that contracts a film or TV play to an actor or actress 5cm × 5cm and discards agricultural polyethylene mulch, cleaned with clear water Completely, it successively impregnates for 24 hours in methylene chloride and methanol, then is cleaned 3 times with ultrapure water respectively, film is fixed on copper after drying On silk, being placed in 100mL concentration is 1mg/L respectively to carry out Static Adsorption in the aqueous solution of DBP, BBP and DNOP (comparative example) Experiment, every 30min sampling are primary.Film after absorption is cut into fragment, with reference to USEPA 3510c method, uses 7mL, 5mL bis- respectively Chloromethanes liquid liquid ultrasonic extraction 2 times, combining extraction liquid, which is blown with 0.22 μm of organic phase filter filtering in 35 DEG C of nitrogen, to be volatilized, and uses chromatography Grade methanol (be purchased from α Cygni friend) constant volume is to 1.5mL.Using Ultra Performance Liquid Chromatography instrument (HPLC) (model Series 200, Perkin Elmer) analysis detection, specific adsorpting data is shown in Table shown in 1~table 3, and specific adsorption curve is shown in Fig. 1, adsorption equilibrium value See Fig. 2.
Table 1:1mg/L DBP adsorption experiment related data
Table 2:1mg/L BBP adsorption experiment related data
Table 3:1mg/L DNOP adsorption experiment related data
Embodiment 2
With the comparison of common polythene adsorbent: the exhaust gas agricultural polyethylene mulch in embodiment 1 being replaced with common poly- Vinyl film is thin, and experimentation is identical, and obtained adsorpting data is shown in Table 4, and specific adsorption curve is shown in Fig. 1, adsorption equilibrium Value is shown in Fig. 2.
4 1mg/L DBP adsorption experiment related data of table
From table 1~4 and Fig. 1~2: waste and old agricultural polyethylene mulch has very strong adsorption capacity to DBP and BBP, Every 5cm × 5cm discards agricultural polyethylene mulch and respectively reaches 0.0335 and 0.0239mg to the adsorption saturation amount of DBP and BBP, and It is better than Plain PE film to the adsorption capacity of DBP, and common polythene film adsorbs 0.0233mg to the saturation of DBP.
3 films of embodiment-water partition coefficient KPE,wMeasurement:
The aqueous solution for the DBP that concentration is 0.1,1,5,10mg/L is respectively configured, carries out Static Adsorption extremely saturation (for 24 hours), Remaining experimentation is the same as embodiment 1.C in following formula (1-1)PEThe concentration ng/g, C being enriched on sampling film when to balanceWWater when to balance In Freely dissolved concentration ng/mL.Using subtract poor method calculate take out film after in water DBP concentration be CW.With CWFor abscissa, CPE For ordinate mapping, slope is film-water partition coefficient KPE,w.This model equation can be used for calculating organic dirt in practical water body Contaminate object concentration.
Test condition are as follows: C18Chromatographic column, 30 DEG C of column temperature, mobile phase is methanol: water=90:10, detection
Wavelength 218nm, sample volume 20 μ L, flow velocity 0.2mL/min, standard curve linear equation are
