몇 개의 한국 대표 토양과 광물에 대하여 역적정 곡선 자료를 이용하여 표면해리상수의 분포 함수를 계산하였다. 공시 시료의 표면해리 상수는 넓게 분포하였으며, 광물 및 무기질 토양의 표면전하는 해리가 매우 약한 산성으로 나타나고. 유기질 토양에서는 중간정도의 산성을 띄우고 있었다.

Using literature data on back titration curves of some typical Korean soils and minerals we calculated the distribution functions of aparent surface dissociation constants for these materials using site heterogeneity approach. The studied materials exhibited broad range of apparent surface dissociation constants. The dominant surface sites for all samples appeared to be very weakly acidic. However, the relative amounts of surface sites differed among particular materials.
