This study was conducted in the adsorption behavior in the gas system on allophane. Adsorption of several organic gases on allophane was carried out by batch system in the low concentration (less than 100 ppm). We used montmorillonite and zeolite-Y as compare materials in these experiments. The results showed that organic gases have been adsorbed higher in the allophane samples than montmorillonite and zeolite-Y.
