Zeolite의 일종인 clinoptilolite를 담배필터 첨가제로 활용하는 연구를 하였다. 입자크기 30 $\pm$ 5 A.S.T.M. mesh의 clinoptilolite와 charcoal 1 : 1 (V/V)로 혼합하여 삼중필터의 cavity부분에 충진했을 때, 1. Cellulose acetate필터에 비하여 nicotine 35%, T.P..M.22%를 감소시켰으며, 2. Gas phase중 n-amyl alcohol등 aliphatic compound와 furan등 cyclic compound를 cellulose acetate filter에 비하여 60$\pm$ 5%를 감소시켰다. 3. Charcoal의 removal efficiency는 40-50% clinoptilolite의 10-20%에 비하여 큰 값이였지만 charcoal은 분자량이 큰 aromatic compound의 removal efficiency가 50$\pm$5%로서 aliphatic compound의 removal efficiency 40: 5%보다 큰 값이였음에 비하여 clinoptilolite는 alcohol과 ketone계열의 분자갹이 작은 화합물의 removal efficiency가 15-20%로 cyclic compounds의 removal efficiency 10-15%에 비하여 보다 큰 값이었다. 이 두물질의 gas phase성분의 흡착기능은 상호 보완적임을 알 수 있었다.
The cavity of triple filter was filled with the mixture of clinoptilolite and charcoal(1:1, V/V). The particle size of clinoptilolite was 30$\pm$5 A.S.T.M mesh. The reduction effects of the important gaseous components by this mixture were obtained as follows: 1) In comparison with the normal cellulose acetate niter, the contents of nicotine and T.P.M. were reduced about 35% and 22% respectively. 2) Many aliphatic and cyclic compounds were also substantially reduced in an average of 60%. 3) In contrast with the charcoal, the removal efficiency of clinoptilolite was revealed as higher (15-20%) in case of aliphatic compounds than the one (10-15%) of cyclic compounds. The above results showed us that the removal function of gaseous components was quite complementary each other (charcoal and clinoptilolite).
