The study focuses on gaseous pollutants such as Formaldehyde (HCHO), Volatile Organic Compounds, VOC (C3H6), Carbon monoxide (CO) and bioaerosol (Bacteria and fungi) . To take activated carbon filters added nano gold (Au)- silver (Ag) , nano Ag and chitosan , tested removal efficiency and adsorption capacity by experimental studies. Moreover ,To be compared with the field studies and experiment studies. The study simulated and discuss air pollutants by used pseudo-first-order model and pseudo-second-order model , in order to achieve appropriate simulation.
The experimental results showed that the removal efficiency of HCHO was increased by 16.33% when chitosan added , but not obvious on VOCs and CO. The removal efficiency of both HCHO and CO were increased by 20% and 7.11% when nano Au-Ag added in activated carbon filter.
The parking lot studies showed the removal efficiency of CO was increased by 7.48% when nano Au-Ag added in activated carbon filter. The removal efficiency of Bacteria was increased by 19.57% , Fungi was increased by 17.1% when nano Ag added in activated carbon filter, the removal efficiency of Bacteria was increased by 35% when chitosan added. The kindergarten (KG) studies the removal efficiency of HCHO was increased by 9.02% when nano Au-Ag added in activated carbon filter. The removal efficiency of HCHO was increased by 42% when chitosan added in activated carbon filter.
Adsorption dynamic model results HCHO 、 C3H6 and CO coincided pseudo-second-order model, it is effectively increased HCHO ,C3H6, CO adsorption capacity by added nano Au-Ag and nano Ag.
