Embodiment 1
[0016] Example 1: Ammonia decontaminant containing soluble metal chloride salt prepared at 25°C
[0017] Under ambient conditions at room temperature 25°C, 1.00kg MgCl 2 ·6H 2 O, 0.70kg FeCl 3 ·6H 2 O and 1.00 kg AlCl 3 ·6H 2 Dissolve O in 4.5L of water, stir for 5 minutes, add 0.10kg of F-4 fluorosurfactant, stir until completely dissolved, then add 0.90kg of ethylene glycol, stir until uniform, and obtain yellow transparent and clear ammonia decontamination agent solution.
[0018] Tested by a pH meter, the pH value of the ammonia decontamination agent is 5.95; the solution remains clear after being left open in the air for 24 hours, and the pH value changes within ±0.1.
[0019] Put the ammonia decontaminant solution in a 6.0L decontaminant storage tank, pressurize it to 2.0Mpa, and release it to a 1.0m area with an ammonia gas concentration of 0.4kg / L through a fine water mist nozzle at a flow rate of 2.0L / min. 3 Simulate the decontamination space, the ammonia conce...
Embodiment 2
[0021] Example 2: Ammonia Decontaminant Containing Soluble Metal Chloride Salt Prepared at -5°C
[0022] Under the ambient condition of -5°C, add 1.2kg of ethylene glycol into 4.5L of water, stir well, then add 0.8kg of MgCl 2 ·6H 2 O, 1.0kg FeCl 3 ·6H 2 O and 0.9 kg AlCl 3 ·6H 2 O was dissolved in the prepared mixed solution of ethylene glycol and water. After it was completely dissolved, 0.015kg of F-4 fluorosurfactant was added and stirred until it was completely dissolved to obtain a yellow transparent and clear ammonia decontamination solution.
[0023] The pH value of the ammonia decontamination agent was tested by a pH meter, and the pH value was 5.68; the solution remained clear after being left open in the air for 24 hours, and the pH value changed within ±0.1, and no freezing phenomenon was observed.
[0024] Put the ammonia decontaminant solution in a 6.0L decontaminant storage tank, pressurize it to 2.0Mpa, and release it to 1.0m through a fine water mist nozz...
Embodiment 3
[0026] Example 3: Ammonia Decontaminant Containing Soluble Sulfates
[0027] Under ambient conditions at room temperature 25°C, add 1.0kg of ethylene glycol into 4.5L of water and stir evenly; then add 1.0kg of MgSO 4 ·6H 2 O, 0.6kg FeCl 3 ·6H 2 O and 3.0kg Al 2 (SO 4 ) 3 18H 2 O was dissolved in the prepared mixed solution of ethylene glycol and water, and then 0.01kg of F-4 fluorosurfactant was added, stirred until completely dissolved, and a yellow transparent and clear ammonia decontaminant solution was obtained.
[0028] Tested by a pH meter, the pH value of the ammonia decontamination agent is 6.02; the solution remains clear after being left open in the air for 24 hours, and the pH value changes within ±0.1.
[0029] Put the decontaminant solution in a 6.0L decontaminant storage tank, pressurize it to 2.0Mpa, and release it to 1.0m through a fine water mist nozzle at a flow rate of 2.0L / min 3 In the simulated decontamination space where the ammonia gas concentra...
