Abstract | This study aimed to investigate the efficiency of aerogel adsorbent produced from combining wastepaper and rice huskto reduce printing pollutants. They were prepared from rice husk residue and three types of wastepaper including two sides-usedpaper (2P), color paper, and newspaper. In printing operation, the concentrations of PM2.5 and TVOC were found at 0.019ยฑ0.005mg/m3and 0.185ยฑ0.005 ppm, respectively. Factorial designs by eighteen experiments revealed the use of color and newspaperwastes resulted higher removal efficiency for PM2.5 whereas the efficiency for TVOC differed compared with the 2P protocol.Moreover, applying 2P achieved better values for both emissions and provided the best aerogel obtained from 2P withoutpretreatment and proportion between rice husk and wastepaper at 1:1 (52.6 and 56.2% for PM2.5 and TVOC, respectively). Todetermine adsorption behavior at equilibrium, the adsorption isotherms were fitted to the Langmuir equation with an R2 value of0.8201 and 0.9973 for PM2.5 and TVOC, respectively. The adsorption sites on the aerogel surface were homogeneous in natureand presented a strong interaction between pollutants and adsorbent fibers. They revealed a maximum capacity for PM2.5 andTVOC of 0.0008 mg/g and 0.099 ppm/g, respectively. |
