Abstract:
Objective To observe the concentration change of 0.5% peracetic acid used as disinfectant in the indoor air. Methods KC-6D gas-sampler and ion chromatograph were employed and sampling interval time was 10-15 min, 7 samples were collected each time in both of the condition of closed and ventilated, the same experiment was repeated for 3 times. Results As the time went on, the concentration change of 0.5% peracetic acid in the indoor air increased from 6.24 mg/m3 to 20.72 mg/m3 in the condition of closed and decreased in the condition of ventilated from 6.92 mg/m3 to 3.36 mg/m3. Conclusion In a closed room of 20 m3, using 500 ml 0.5% peracetic acid, after 30 minutes of disinfection followed by 60 minutes of ventilation, the concentration of peracetic acid will be about 3.36 mg/m3 in the air of the room.
