$200{sim}800nm$ 파장(波長)범위 내에서 Na, $NH_4$, Ca, Al 이온으로 흡착(吸着)된 monocationic zeolite 현탁액(懸濁液)의 광학적(光學的) 특성(特性)을 조사(調査)한 결과(結果)는 다음과 같았다. 1. Zeolite현탁액(懸濁液)의 optical density는 $200{sim}300nm$ 파장(波長)범위에서는 입자(粒子)에 의한 빛의 흡수(吸收). $300{sim}800nm$파장(波長)범위에서는 입자(粒子)에 의한 빛의 산란(散亂)의 영항을 크게 받았다. 2. $380{sim}800nm$ 파장(波長)범위에서의 monocationic zeolite 현탁액(懸濁液)의 optical density는 $Al->Ca->NH_4->Na-zeolite$ 순으로 높았다. 3. Zeolite현탁액(懸濁液)의 농도(濃度)를 측정(測定)할 때는 저농도(低濃度)는 단파장(短波長), 고농도(高濃度)는 장파장(長波長)쪽에서 측정(測定)하는 것이 정확(正確)하였다. 4. Zeolite현탁액내(懸濁液內)의 입자(粒子)들은 쉽게 입단(粒團)을 형성 하였으며 $Al->Ca->Na->NH_4-zeolite$ 순으로 굵은 이단(粒團)이 많았다.
The optical properties of monocationic zeolite suspension adsorbed with each of $Na^+$, $NH_4^+$, $Ca^{2+}$, and $Al^{3+}$ were studied in the wavelength range $200{sim}800nm$. The results were as follows. 1. The optical density of zeolite suspension seemed to be affected by the light absorption of zeolite particles at the wavelength range of $200{sim}300nm$ and by the light scattering of zeolite particles at wavelength of $300{sim}800nm$. 2. At the wavelength range of $380{sim}800nm$, the optical densities of monocationic zeoliteg differed mutually according to adsorbed cations and increased in the order of $Al-;>;Ca-;>;NH_4->;Na-zeolite$ suspension. 3. It was convenient that at the wavelength range of $380{sim}800nm$, the diluted suspension of zeolite was measured in the short wavelength and the concentrated suspension of zeolite was measured in the long wavelength. 4. Zeolite particles in zeolite suspension were aggregated and the size of aggregation size was larger in the order of $Al-;>;Ca-;>;Na-;>;NH_4-zeolite$.
