Example Embodiment

[0034] Example 1

[0035] Preliminarily add 100 μl of immersion and absorption solution to the absorption layer in the passive sampler. Place a small piece of treated environmentally friendly particleboard on figure 2 The sealed space shown by a sealed sampling bottle 1 is placed under the passive sampler. Heat and seal the sampling bottle to 40°C. The material volatilizes organic acid, which is absorbed by the immersion absorption liquid on the absorption layer in the passive sampler to generate the test object. After sampling at 40°C for 4 hours, the absorption layer is taken out and placed in 5mL In a blank test polypropylene plastic bottle or glass bottle with ultrapure water, close the bottle cap tightly and ultrasonic for 15 minutes to extract the detected substance on the absorption layer, filter the obtained sample solution through a 0.22μm filter and use the ion chromatography system (Dionex-320) detection. The chromatographic conditions are: injection volume 25μL, an...

Abstract

The invention discloses a rapid detection method of volatile acid in exhibited materials collected by a museum based on passive sampling. The method comprises the steps of: putting the exhibited materials collected by the museum, which is to be detected, into a confined space, collecting the volatile acid diffused by the exhibited collected materials at certain temperature by using a passive sampling device, after collecting for a period of time, taking out a passive sampler, extracting an object to be detected by using ultrapure water, carrying out quantitative detection by applying an ion chromatography system, and carrying out evaluation on the volatile acid in the exhibited materials collected by the museum through conversion. By applying the passive sampling device, the invention designs a static semi-quantitative evaluation and analysis method specific to the volatile acid in the exhibited materials collected by the museum, which can better objectively evaluate the pollution condition of the volatile in the exhibited materials collected by the museum in the confined space such as the inside of the museum display cases, and moreover, the analysis detection method is simple and rapid and is convenient to large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of material testing, and relates to a rapid detection method for volatile acids in museum collection and exhibition materials, in particular to a rapid detection method for volatile acids in museum collection and exhibition materials based on passive sampling. Background technique [0002] With the continuous development of modern industry, there are more and more types of materials such as wood, plastics, textiles, paints, adhesives, polymer materials, composite materials, etc., and more and more materials can be selected for storage, display and decoration by museums. more and more. These storage, display and decoration materials can slowly release or degrade to produce various volatile components, such as formic acid, acetic acid, sulfur-containing compounds, olefins, carbonyl compounds, etc. In a closed display cabinet or warehouse, the concentration of these pollutants will be continuously released fro...
