Abstract
액체혼합물중에 녹아있는 용질을 불활성기체로서 탈거시켜서 용질농도의 감소속도로부터 무한희석활동도계수（γi∞）를 구하고 다른 방법으로 얻은 문헌값과 비교하여 정확한 값임을 확인하였다. 이 결과로부터 탈거법을 비휘발성용매계에는 물론이고 휘발성용매계에도 적용하여 γi∞를 구할 수 있음을 알았다. 그리고 실험조작과 해석상의 문제점을 면밀하게 검토하였다.
The activity coefficients at infinite dilution of several solutes were determined by measuring the stripping rates of solutes in nonvolatile and volatile solvents. The results agree quite well with those in the literature obtained by other experimental methods. As the reslt, it is found that the stripping method can be applied to even volatile-solvent systems. In addition, experimental technique and the questions of data reduction are discussed and thoroughly examined.
