Embodiment 1
[0021] A kind of toluene detection reagent of the present embodiment is made from the following raw materials in parts by weight: 34 parts of ethanol, 10 parts of strong base, 6 parts of p-sulfonamide benzoic acid, 19 parts of sodium iodide, 9 parts of phenanthroline, α - 10 parts of ketoglutaric acid, 6 parts of sulfonamide benzoic acid and 16 parts of acetic acid.
[0022] The strong base is beryllium hydroxide.
[0023] The preparation method of the toluene detection reagent in this example is: mix the above components evenly.
[0024] The method of using the toluene detection reagent in this embodiment is as follows: absorb the gas to be tested and pass it into the detection reagent, heat it to 45-50°C, let it stand for 15-20 minutes, and observe the color change. The change of color proves that the concentration of toluene in the gas to be tested is greater than 0.5mg / m3.
Embodiment 2
[0026] A kind of toluene detection reagent of the present embodiment is made from the following raw materials in parts by weight: 30 parts of ethanol, 6 parts of strong base, 2 parts of p-sulfonamide benzoic acid, 15 parts of sodium iodide, 5 parts of phenanthroline, α - 6 parts of ketoglutaric acid, 2 parts of sulfonamide benzoic acid and 11 parts of acetic acid.
[0027] The strong base is beryllium hydroxide.
[0028] The preparation method of the toluene detection reagent in this example is: mix the above components evenly.
[0029] The method of using the toluene detection reagent in this embodiment is as follows: absorb the gas to be tested and pass it into the detection reagent, heat it to 45-50°C, let it stand for 15-20 minutes, and observe the color change. The change of color proves that the concentration of toluene in the gas to be tested is greater than 0.5mg / m3.
Embodiment 3
[0031] A kind of toluene detection reagent of the present embodiment is made from the following raw materials in parts by weight: 31 parts of ethanol, 7 parts of strong base, 3 parts of p-sulfonamide benzoic acid, 16 parts of sodium iodide, 6 parts of phenanthroline, α - 7 parts of ketoglutaric acid, 3 parts of sulfonamide benzoic acid and 12 parts of acetic acid.
[0032] The strong base is lithium hydroxide.
[0033] The preparation method of the toluene detection reagent in this example is: mix the above components evenly.
[0034] The method of using the toluene detection reagent in this embodiment is as follows: absorb the gas to be tested and pass it into the detection reagent, heat it to 45-50°C, let it stand for 15-20 minutes, and observe the color change. The change of color proves that the concentration of toluene in the gas to be tested is greater than 0.5mg / m3.
