Problems solved by technology

However, there is no report on the preparation of traceable luminescent haze particles by combining luminescent nanoparticles and haze particles.
[0006] In addition, due to the complex composition of smog particles and their certain pathogenicity and toxicity, the existing technology generally uses model materials to study the process of smog particles invading the human body, but the preparation of model materials is complicated and the degree of simulation is not high. Therefore, there is an urgent need for a simpler and more efficient tracer method for haze particles

preparation example Construction

[0040] A method for preparing a traceable smog composite luminescent material, the steps are as follows:

[0041] 1) Soak the smog particles collected on the filter membrane of the atmospheric collector in an organic solvent, detect the acidity and alkalinity and retain the acidic smog particles, freeze-dry, and obtain the processed smog particles;

[0042] 2) Disperse and dissolve the inorganic luminescent particles into an organic solvent after heating, stirring, ultrasonic treatment, etc., to obtain a dispersion of inorganic luminescent particles, and add the treated haze particles into the dispersion of inorganic luminescent particles according to the proportion, and continue to stir and ultrasonically , to obtain traceable haze composite material solution;

[0043] 3) drying the traceable haze composite material solution to obtain the traceable haze particle composite material;

[0044] The haze particles collected on the filter membrane of the atmospheric collector are ...

Embodiment 1

[0053] 1) Soak the glass fiber filter membrane that collected PM2.5 smog particles with the atmospheric collector (MH1200, atmospheric particle sampler, Yancheng Tianyue Instrument Co., Ltd.) into ethanol for 12 hours, take out the filter membrane, and use acid Alkaline indicator detects the acidity and alkalinity of the soaking solution gained, and the acidic ethanol solution that is dissolved with smog particles is placed in a vacuum freeze-drying box (Scientz-ND, freeze-drying machine, Ningbo Xinzhi Biotechnology Co., Ltd.), Set the freezing temperature to -200°C, freeze-dry for 50 hours, and fully dry to obtain the processed smog particles;

[0054] 2) ZnGa prepared by solid-state method 2 o 4 : Cr 3+ (According to patent CN201510650991.2) Dissolve 0.1g of particles into 10ml of ethanol solvent, stir magnetically at room temperature for 1h to fully mix and disperse to obtain inorganic luminescent particle dispersion, add ZnGa to the treated haze particles according to th...

Embodiment 2

[0058] Using the same method as in Example 1, use the PM 10 and acidic haze particles collected by the atmospheric collector (MH1200, atmospheric particle sampler, Yancheng Tianyue Instrument Co., Ltd.) to make a traceable haze particle composite material .

[0059] The traceable smog particle composite material prepared in this example was used to characterize the properties of the sample, the particle size was at the micron level, and other performance test results were similar to Example 1.

Abstract

The invention relates to a composite capable of tracing haze particles and a preparation method of the composite. The composite capable of tracing the haze particles is prepared from acidic haze particles collected from air and an inorganic luminescent material with functionalized surface through covalent coupling based on hydroxyl bonds and hydrogen bonds. The composite with a micro-nano shell coating structure has properties of stable luminescence, traceability, high biological penetration and the like, and can be used as a biomaterial and a functional material for haze formation, hazards, defense simulation and pathological study in related fields.

Description

technical field [0001] The invention belongs to the field of biological materials, in particular to a traceable haze particle composite material and a preparation method thereof. Background technique [0002] With the rapid expansion of my country's economic scale and the acceleration of urbanization, atmospheric aerosol pollution is becoming more and more serious, and there are more and more incidents of visibility deterioration caused by aerosols. Smog has become one of the important reasons that endanger human public health. [0003] After the smog particles enter the lung tissue of the human body, how do the lungs resist the particle invasion and how are they excreted from the body? How do smog particles invade the alveoli and damage the respiratory system? These issues have been receiving much attention. The key to solving the problem is to clearly mark and trace the road map of haze particles invading the alveoli and exiting the body. [0004] Luminescent materials ...
