동일의 bubble aeration tank에서 5종류의 유기물（benzene, carbon tetrachloride, chloroform, 1, 2-dichloroethane, 1, 1, 2-trichloroethane）을 물로부터 동시에 stripping시킴으로써, 여러 공기유속에서 각 유기물에 대한 총괄물질이동용량계수가 결정되었다. 총괄물질이동용량계수와 Henry정수 사이의 관계를 이용하여, 5종류의 유기물에 대하여 일정값의 기상 및 액상물질이동용량계수가 동시에 얻어졌다. Mackay가 제안한 관계 : k_G aD_G^0.67과 k_L aD_L^0.5를 이용하여 유기물에 대한 기상 및 액상물질이동용량계수는 공기-물계면에서 SO₂에 대한 (k_Ga)so₂와 O₂에 대한 (k_La)o₂로 각각 환산되어졌다. 환산되어진 (k_Ga)so₂는 Botton 등에 의해 얻어진 data보다 2배 정도 작았지만, 환산되어진 (k_La)o₂는 Shah 등의 data와 잘 일치하였다.
소량의 탄산나트륨이 bubble aeration tank에 첨가되었을 때 기상 및 액상물질이동용량계수의 상당한 증가가 있었다. 물질이동용량계수의 증가는 탄산나트륨 수용액중에서의 기포크기의 감소 혹은 물질이동계면적의 증가로 인한 결과였다.

By the simultaneous stripping of five organic solutes （benzene, carbon tetrachloride, chloroform, 1, 2-dichloroethane, 1, 1, 2-trichloroethane） from water in the same bubble aeration tank, the overall volumetric mass transfer coefficients for each solute were determined at various air flow rates. Using the relationship between the overall volumetric mass transfer coefficient and Henry's law constant, the same volumetric gas-phase and liquid-phase mass transfer coefficients for five organic solutes, respectively, were obtained simultaneously. The volumetric gas- and liquid-phase mass transfer coefficients for organic solutes were then converted, respectively, using the relationships proposed by Mackay et al. : k_GaD_G^0.67 and k_L aD_L^0.5 into (k_Ga)so₂ for sulfur dioxide gas and (k_La)o₂ for oxygen gas at the air-water interface. The converted (k_La)o₂ were found in good agreement with the data of Shah et al., while the converted (k_Ga)so₂ were found to be about twice as small as the data obtained by Botton et al.
A considerable increase in the volumetric gas- and liquid-phase mass transfer coefficients was observed when small amount of sodium carbonate was added onto the bubble areation tank. The increase in the volumetric mass transfer coefficients was considered to result from the decrease in bubble size or increase in interfacial mass transfer area in aqueous sodium carbonate solution.
