Clinoptilolite ノ キュウチャクノウ III サンショリ コウカ ト ソノ ガスクロマトグラフィー ニヨル ケントウ

Clinoptilolite (occured in Itaya, Yamagata pref.) was dried after boiling HCl aqueous solution, and the effects of treatment toward the surface area of clinoptilolite and the gas chromatogram with several organic and inorganic gases were studied. The results were as follows; 1. Surface area did not increase so much by acid treatment. 2. The surface area of 0.5 N HCl treated clinoptilolite dried at 120℃ was the same as that of untreated one dried at 300℃. This property is a merit of clinoptilolite when used as an adsorbent. 3. When acid treated clinoptilolite was used as the column packing of gas chromatograph, each Components of gas mixed O_2, N_2, CH_4 and CO, were seperated clearly at room temperature, satisfactrily sharp. 4. Inserting the experimental data and the chromatographic peaks were to van Deemter\u27s equation. it was found that the rate of diffusion of the above gases into clinoptilolite was increased by acid treatment. 5. The separation of lower hydrocarbons, CH_4, C_2H_6, C_3H_8, iso-C_4H_ and n- C_4H_ was also possible by the use of acid treated clinoptilolite packing. The heat of adsorption of these gases showed that this mechanism of separation was not caused by molecular sieve effect of clinoptilolite
