Experimental study on the adsorption performance of TVOC by new rGO composite filter material

It is of great significance to effectively control the impact of Total Volatile Organic Compounds (TVOC) on personnel's physical health in working and living environments. This paperconducts adsorption experiments on TVOC in commonly used paints using a new type of rGO composite filter material. The adsorption performance and desorption performance are studied under different conditions such as temperature, humidity, airflow velocity, and initial concentration. The results showed that the new filter material has good adsorption performance for TVOC in paint. With the increase of TVOC gas concentration, airflow velocity, temperature, and humidity, the penetration time of rGO composite filter material will continuously shorten. After five cycles, the desorption rates of displacement desorption and heating desorption reached 82.3% and 61.2%, respectively, and the displacement desorption efficiency was 25.6% higher than the heating desorption efficiency. Itprovides reference for effectively removing TVOC, whichis helpful for ensuring air quality in special industries.
