Embodiment 1

[0018] A styrene detection reagent of this embodiment is prepared from the following raw materials by weight: 34 parts by weight of ethanol, 10 parts by strong base, 6 parts by phenanthroline, 19 parts by sodium nitrite, 9 parts by calcium chloride, and trichloro 10 parts of antimony, 6 parts of hydroxyethylidene diphosphonic acid and 16 parts of acetone. The strong base is beryllium hydroxide.

[0019] The preparation method of the styrene detection reagent in this embodiment is as follows: the above-mentioned components are mixed uniformly.

[0020] The method of using the styrene detection reagent in this embodiment is: suck the gas to be tested into the detection reagent, heat it to 45-50° C., stand for 15-20 minutes, and observe the color change. The color change proves that the styrene concentration in the gas to be measured is greater than 0.5 mg / m3.

Embodiment 2

[0022] A styrene detection reagent of this embodiment is prepared from the following raw materials in parts by weight: 30 parts by weight of ethanol, 6 parts by strong base, 2 parts by phenanthroline, 15 parts by sodium nitrite, 5 parts by calcium chloride, and trichloride 6 parts of antimony, 2 parts of hydroxyethylidene diphosphonic acid and 11 parts of acetone. The strong base is beryllium hydroxide.

[0023] The preparation method of the styrene detection reagent in this embodiment is as follows: the above-mentioned components are mixed uniformly.

[0024] The method of using the styrene detection reagent in this embodiment is: suck the gas to be tested into the detection reagent, heat it to 45-50° C., stand for 15-20 minutes, and observe the color change. The color change proves that the styrene concentration in the gas to be measured is greater than 0.5 mg / m3.

Embodiment 3

[0026] A styrene detection reagent of this embodiment is prepared from the following parts by weight of raw materials: 31 parts by weight of ethanol, 7 parts by strong base, 3 parts by phenanthroline, 16 parts by sodium nitrite, 6 parts by calcium chloride, and trichloride 7 parts of antimony, 3 parts of hydroxy ethylidene diphosphonic acid and 12 parts of acetone. The strong base is lithium hydroxide.

[0027] The preparation method of the styrene detection reagent in this embodiment is as follows: the above-mentioned components are mixed uniformly.

[0028] The method of using the styrene detection reagent in this embodiment is: suck the gas to be tested into the detection reagent, heat it to 45-50° C., stand for 15-20 minutes, and observe the color change. The color change proves that the styrene concentration in the gas to be measured is greater than 0.5 mg / m3.

Abstract

The invention discloses a styrene detection reagent and a preparation method thereof. The styrene detection reagent comprises the following raw materials in parts by weight: 30 to 34 parts of ethanol, 6 to 10 parts of strong base, 2 to 6 parts of phenanthroline, 15 to 19 parts of sodium nitrite, 5 to 9 parts of calcium chloride, 6 to 10 parts of antimony trichloride, 2 to 6 parts of hydroxyethylidene diphosphonic acid and 11 to 16 parts of acetone. The styrene detection reagent is used for on-site analysis and detection, is convenient to carry, easy to use, rapid and flexible and has advantages of intuitiveness, rapidness, trace amount, accuracy and high reproducibility; moreover, the preparation method is simple, the production cost is low, and the environmental protection is realized.

Description

technical field [0001] The invention relates to a detection reagent, in particular to a detection reagent for styrene in indoor air and a preparation method thereof. Background technique [0002] In recent years, my country has successively formulated a series of standards related to the indoor environment, from the use of building decoration materials to the limitation of pollutant content in indoor air, and strictly monitors the indoor environment in all directions to ensure the health of the people. Therefore, people often think that modern living conditions are constantly improving, and indoor environmental pollution has been controlled. Actually otherwise, people are far from reaching enough awareness to the harm of indoor environmental pollution. [0003] It should be noted that while my country's economy is developing rapidly, indoor environmental pollution caused by construction, decoration and furniture has become a major killer affecting people's health.
