specific Embodiment approach 1

[0016] Specific embodiment one: the preparation method of the ultraviolet detection test paper of this embodiment is carried out according to the following steps:

[0017] 1. Add (80~120)mg polyvinylpyrrolidone into 2ml water, add (5~10)mg viologen, (10~20)mg polyoxometalate, stir well, then add (10~15)mg polyvinylpyrrolidone Sodium styrene sulfonate, then add (15-20) mg polyethyleneimine to obtain a mixed solution;

[0018] 2. Apply the mixed solution evenly on a filter paper sheet with a specification of 1cm×5cm, and let it dry naturally to obtain the ultraviolet detection test paper.

[0019] The general structural formula of viologen in the present embodiment is:

[0020]

[0021] The highly sensitive ultraviolet detection test paper prepared in this embodiment does not need to use complex ultraviolet intensity detection units, photoelectric conversion controllers, memory, input and output units, and power supply units when detecting ultraviolet intensity. A small 6w ...

specific Embodiment approach 2

[0022] Embodiment 2: This embodiment differs from Embodiment 1 in that the amount of polyvinylpyrrolidone added in step 1 is 90 mg. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0023] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the amount of viologen added in step 1 is 9 mg. Others are the same as those in the first or second embodiment.

Abstract

The invention discloses a preparation method for ultraviolet test paper, and relates to the preparation method of test paper. The invention is to solve the problems that the existing ultraviolet intensity detection method is complex in implementing device, tedious and high in cost. The method includes the steps of: adding polyvinylpyrrolidone into water, adding purpurine and polyoxometallate, mixing uniformly, adding sodium polystyrenesulfonate, then adding polyethyleneimine to obtain mixed liquor; uniformly coating the filter paper with the mixed liquor, airing naturally, and thereby obtaining the ultraviolet test paper. When the ultraviolet test paper with high sensitivity prepared by the method of the invention is used for detecting the ultraviolet intensity, no complex electric circuits and devices are needed, and color comparison can be achieved only by a 6w small ultraviolet lamp in fluorescent color comparison, thus being simple and easy to implement and meanwhile greatly saving in time; considering from the view of production, more than 90% cost can be saved compared with the current test facilities. The invention belongs to the field of preparation of test paper.

Description

technical field [0001] The invention relates to a preparation method of a detection test paper. Background technique [0002] The spectral range of ultraviolet (UV) radiation in the solar radiation spectrum is between 100-400nm, and its energy only accounts for 8% of the total solar radiation. According to the biological effects of different wavelengths of ultraviolet rays, it can be divided into three parts: ultraviolet rays Section A (UV-A), with a wavelength of 320-400nm, accounts for about 6% of the total solar radiation. This part has weak biological effects, mainly pigmentation. Ultraviolet B segment (UV-B), with a wavelength of 290-320nm, accounts for about 1.5% of the total solar radiation. This segment has a greater impact on the human body. Its main function is anti-rickets and erythema. One of the main causes of capacity decline. Ultraviolet C segment (UV-C), with a wavelength of 100-290nm, accounts for about 0.5 of the total solar radiation, and cannot reach th...
