Embodiment 1

[0029] Please refer to figure 1 , figure 1 It is a schematic flowchart of a bionic artificial mussel method for detecting seawater organic pollutants according to the present invention. A bionic artificial mussel method for detection of seawater organic pollutants, said method comprising the following steps:

[0030] Step S1, prepare four medium and low density polyethylene film tubes, according to multiple tests, the preferred medium and low density polyethylene film tubes are 22cm long, 5cm wide, and 50 μm in thickness, and the film thickness and film area of ​​this size can enrich organic matter The rate is high.

[0031] Step S2, use a pipette gun to add trioleate into the medium and low density polyethylene film tube of step S1; wherein, after adding trioleate into the polyethylene film tube, it needs to be spread flat on the table, with the help of a vessel Tape and squeeze to evenly distribute the trioleate throughout the polyethylene film tube except for 1 cm at bot...

Abstract

The invention relates to a mimetic artificial mussel method for detection of organic pollutants in seawater. The method comprises the following steps: S1, preparing four polyethylene film tubes; S2, adding trioleate into the polyethylene film tubes in the step S1 by the use of a pipette; S3, sealing two ends of each polyethylene film tube in the step S2 by the use of a plastic welding machine; S4, fixing the polyethylene film tubes obtained in the step S3 into a stainless steel wire filter cartridge; and S5, sealing the stainless steel wire filter cartridge in the step S4 by the use of mesh. The method has the following advantages: hanging and sampling are convenient and are not limited by natural conditions; biological silt influence is effectively minimized; differences caused by sex, growth cycle and robust degree of natural mussels and sea area conditions can be overcome; biochemical degradation effect in biological body also can be overcome; the defect that mussels cannot live due to serious pollution of a certain sea areas is avoided; test data has higher comparability; and the method has a good application prospect, and detection of organic pollutants in seawater can be carried out effectively by the method.

Description

technical field [0001] The invention relates to the technical field of bioprevention, in particular to a bionic artificial mussel method for detecting seawater organic pollutants. Background technique [0002] About 80% of the world's coastal waters are polluted by petroleum hydrocarbons, polycyclic aromatic hydrocarbons, organic chlorinated biphenyls, organic matter and eutrophication, among which petroleum hydrocarbon pollution and eutrophication are particularly prominent. [0003] The concentration of organic pollutants in seawater is very low, and it is very difficult to directly measure them. Traditional chemical determination methods need to spend a lot of time and financial resources to collect and process large volumes of water samples, and the substances to be analyzed are easily lost during the analysis process. In addition, the obtained results can not reflect the bioavailability of pollutants in water and their harm and degree to the ecological environment, let...
