Abstract

경북영일지역에서 산출되는 천연 zeolite를 수처리 혹은 타분야에 이용하기 위해 X선회절실험, 양이온교환용량 측정, 이온교환평형관계 측정 그리고 이온교환반응열 등, 이온교환특성에 대한 연구를 행하였다. 아울러 국산천연 zeolite와의 비교검토를 위해, 일본추전산, 미국 California산에 대한 실험도 함께 행하였다.
질량작용의 법칙으로부터 유도되어 천연 Zeolite에 적용된 양이온의 선택계수는 유기이온 교환 수지와 같이 일정하지 않고 입자내의 농도의 함수로 주어졌다.
The characteristics of natural zeolite originated from Kyungbuk, Korea such as X-ray diffraction, cation exchange capacity, ion exchange equilibrium and ion exchange reaction heats were investigated for application to wastewater treatment and other use. Japanese and American natural zeolite samples were also tested to compare with Korean sample. The selectivity coefficient of cation in these materials defined from mass action law does not a constant value as in the case of organic exchange resin.
