Embodiment 1

[0040] The present embodiment provides a kind of colored substance rapid detection test paper based on porous metal-organic complex material, which comprises blank test paper, and its surface is coated with three kinds of porous metal-organic complex material strip coatings arranged at intervals, Polyvinyl alcohol hybrid coatings of Cu(APM), MIP-202(Zr) and UiO-66(Zr), respectively.

[0041] Cu(APM), MIP-202(Zr) and UiO-66(Zr) are all synthesized by existing technology, specifically, the following methods can be used for synthesis:

[0042] Preparation of Cu(APM): 2.56 parts by mass of aspartame and 4.5 parts by mass of copper sulfate were dissolved and dispersed in 20 parts by mass of methanol / water mixed solution, and placed in an oven at 80° C. for 24 hours. After cooling, wash off residual substances with water and methanol solvents, and then dry in an oven at 60°C.

[0043] Preparation of MIP-202(Zr): 2.8 parts by mass of L-aspartic acid and 2.33 parts by mass of zirconi...

Embodiment 2

[0048] In this embodiment, the test paper of Example 1 is used to detect 10 kinds of colored dye substances, and the adsorption effect of the three metal-organic complexes of the test paper on these 10 kinds of substances is tested.

[0049] Concentrations of 0.02mM algal red B, 0.02mM carmine, 0.05mM methyl red, 0.02mM amaranth, 0.03mM sunset yellow, 0.02mM tartrazine, 0.01mM brilliant blue, 0.5mM indigo, 0.04mM bromophenol blue , and 0.02mM methylene blue, the above 10 kinds of colored substance aqueous solution; will contain three porous metal-organic complex materials (blue powder material Cu (APM), white powder material MIP-202 (Zr) and white powder material UiO- 66 (Zr) test paper, respectively inserted into the above 10 kinds of colored substance aqueous solution; using the capillary effect, the solution soaks the test paper, and the three porous coating materials absorb the analytes in the solution.

[0050] The absorbance changes of the centrifuged supernatants at the...

Embodiment 3

[0058] This embodiment provides a method for constructing a colored substance identification database, taking the 10 colored dye substances in Example 2 as an example, such as figure 1 As shown, after the three adsorbent materials adsorbed 10 kinds of dye substances, the powder color has obvious difference, which is mainly due to the difference in the selective adsorption of different dyes caused by the properties of the surface of the material, which is finally reflected in the color change of the material. Identify the colors of the three materials after the colored substances are adsorbed, and convert them into RGB color values, as shown in Table 3. Finally, the RGB color values ​​of the three materials were converted into hexadecimal color codes, as shown in Table 4; and the database relationship between the hexadecimal color codes and the analytes was established. The process of constructing the identification database of colored substances is as follows: Figure 4 As sh...

Abstract

The invention discloses porous metal-organic complex material-based colored substance rapid detection test paper. The porous metal-organic complex material-based colored substance rapid detection test paper comprises blank test paper; the surface of the blank test paper is coated with a strip-shaped coating composed of three porous metal-organic complex material arranged at intervals, i.e., a polyvinyl alcohol mixed coating of Cu (APM), MIP-202 (Zr) and UiO-66 (Zr). The invention also discloses a detection method of the test paper and a method for constructing a colored substance identification database by using the test paper. According to the method, the three different adsorbents are used for selectively adsorbing dye molecules, and the color of the adsorbents has obvious anisotropy after the adsorbents adsorb colored substances, so that the method can be used for quickly identifying the colored dye substances at low concentration; meanwhile, color matrixes of the three materials are constructed and coded into computer languages, and the method can be used for development of related electronic detection equipment.

Description

technical field [0001] The invention relates to the technical field of detection of colored substances, in particular to a rapid detection test paper for colored substances based on a porous metal-organic complex material, a detection method and an application in the direction of dataization. Background technique [0002] The water body contains a large amount of organic pollutants, which are oxidizing or reducing, which reduces the dissolved oxygen content in the water and affects the ecosystem. Among them, organic dyes such as azobenzene dyes and phenothiazine dyes have strong bioaccumulation and persistence, and have blood toxicity, neurotoxicity and carcinogenic effects. Therefore, the detection of such organic pollutants is very important. However, at present, the detection of such substances mainly relies on large-scale equipment and instruments. The detection cost is high, the consumption of reagents is large, and the test time is long. It is urgent to develop new de...
