碩士 === 國立中央大學 === 環境工程研究所 === 103 === In this study, we discussed about low Henry’s constant of organic compounds. The goal of this research is to determine the volatilization rate of such compounds and to campare the mass transfer coefficient (KOL) between organic compounds in different environmental conditions.In this study we also explored the KOL of a characteristic compared at same condition both in water and organic madia . In this research, we measured the KOL value of low Henry’s constant of organic compounds with a semi-closed system of the model factory concept under different gas and liquid turbulence, and the results obtained are used to compare the rate of volatilization of organic compounds. The results showed that low Henry’s constant of organic compounds which we selected can meet the first-order kinetic, and the resulting volatilization rate constants (k) are used to calculate the KOL value by mass balance reaction. The obtained results can be found, the low Henry’s constant of organic compounds and KOL are positive relationship, and it will increase with increasing the intensity of turbulence. When Henry’s constant value are similar, the volatilization rate of organic compounds was vaired depending on different physical and chemical properties. Finally, we put the same type of organic chemical in the water and found that the compounds interfere with each other, then the phenomenon of competition is generated.
