Description

Technical Field

[0001] The utility model relates to the technical field of fluorescence analysis equipment, and in particular to a portable fluorescence detection device based on a smart phone colorimetric platform. Background Art

[0002] As the amount of Cr(VI) discharged into the environment continues to increase, it has a negative impact on medicine, ecology and the environment. However, the commonly used methods for detecting Cr(VI) require a long sample preparation process, complex operations and expensive equipment. In contrast, smartphone-based fluorescent visual detection methods have received great attention as a portable on-site sensing application platform due to their high sensitivity, good selectivity and easy operation. Specifically, the smartphone-based fluorescent sensing system converts the RGB (red, green, blue) component values ​​of the image into fluorescence intensity. Although great achievements have been made in the visual detection of heavy metals, there is still a lot of room for exploration and improvement, such as the relationship with Cr(VI) has not yet been widely used.

[0003] Furthermore, by combining fluorescence detection technology with smartphones, smartphones can be used to identify the RGB values ​​corresponding to the fluorescence detection materials, and a linear relationship between the pollutant concentration and the RGB value can be established, thereby achieving rapid and quantitative detection of pollutant concentrations on site. Based on the above, it is urgent to develop a portable and highly applicable fluorescence detection device based on a smartphone colorimetric platform. Summary of the invention

[0004] The purpose of the utility model is to solve the problems existing in the prior art and to provide a portable fluorescence detection device based on a smart phone colorimetric platform.

[0005] A portable fluorescence detection device based on a smartphone colorimetric platform comprises a box body, a top plate, a smartphone and an ultraviolet lamp, wherein left and right sliding doors are provided on the front side panel of the box body, the ultraviolet lamp is located inside the box body and fixedly arranged on the back side panel of the box body; the smartphone is arranged outside the box body and aligned with the left and right sliding doors, and the top plate is movably arranged on the box body.

[0006] Support rails are arranged between the left and right sliding doors and the box body.

[0007] Black card paper is arranged on the bottom plate of the box body.

[0008] The box body and the top plate are made of opaque and non-reflective black material.

[0009] The wavelength of the ultraviolet lamp is 365 nm.

[0010] The working process and working principle of this utility model:

[0011] The fluorescent material that has captured pollutants is placed on black cardboard, which is then placed on a base plate. The ultraviolet light is then turned on, and the position of the smartphone is adjusted according to the position of the fluorescent material on the base plate, and photos are taken from the front observation port. The specific RGB values ​​of the photos of the fluorescent material are analyzed by the smartphone colorimetric platform, thereby establishing a standard curve corresponding to RGB values ​​and pollutants of different known concentrations. The curve can be used to quickly calculate pollutants of unknown concentrations from the measured RGB values, thereby achieving the purpose of rapid and real-time quantitative on-site analysis of pollutant concentrations.

[0012] The utility model is in a darkroom state, effectively avoiding the influence of the external environment on the detection results. In order to verify the fluorescence detection effect of the utility model, the fluorescence effect of Cr(VI) in water is detected by using the core-shell hybrid fluorescent MOG@COP / sodium alginate composite microspheres, and the colorimeter App on the smartphone can accurately analyze its RGB value to ensure the accuracy of the photo results.

[0013] Beneficial effects of the utility model:

[0014] The utility model utilizes a smartphone colorimetric platform in combination with fluorescence detection technology, captures the RGB values ​​during the fluorescence detection process through the smartphone digital camera, and establishes a standard curve of pollutant concentration and RGB value. It can quickly and quantitatively analyze on-site pollutant concentrations in real time. It is easy to carry, simple to operate, less affected by the environment, and has a wide range of applications, making it convenient for inspectors to conduct on-site analysis and detection.
