This study examines the ability of nanozeolite-geopolyme ras adsorbent material for motor vehicle emissions. There were three samples that have been synthesized by varying metakaolin and rice husk ash masses. Nanozeolite-geopolymer samples were synthesized through geopolymerization method at 70°C by mixing metakaolin with rice husk ash and activated with NaOH solution. Samples were recurring at 200°C to improve the crystalline level. Based on the XRD characterization of the three samples, two of them contain zeolite X, namely ZG_A (100% metakaolin, ASP 0%) and ZG_B (metakaolin: ASP, 2: 1). However, zeolite X phase most conceived by ZG_A. Therefore, the ZG_A sample was then used as adsorbent to absorb motor vehicle exhaust. The tests were performed four times with time variation of 10, 20, 30, and 40 minutes. The XRD results showed that the material was successfully absorbed lead oxide, manganese oxide and phosphorus which are hazardous compounds when inhale by human being. |
