Solute-Gas Equilibria in Multi-Organic Aqueous Systems
Abstract
The objective of this research was to study the effects of temperature, ionic strength, and presence of additional organics on the aqueous solution/gas equilibria of a variety of chlorinated organic compounds: 1,1,1- trichloroethane, tetrachloroethylene, trichloroethylene, chloroform, methylene chloride, and o-dichlorobenzene. Henry's Constant for each alone was determined in pure water over the temperature range, 10 deg - 30 deg C, using an equilibrium, batch stripping reactor. Data were fit to a regression equation. Henry's constants for selected organic solvents were determined at ionic strengths up to 1.0 M (KC1). Results suggest that ionic strength effects on activity can be ignored in systems processing ionic strengths less than 0.07 M. Henry's constants for organic solvents dissolved in multicomponent aqueous mixtures of other organic solvents were measured. It was found that relatively small concentrations of the organic solvents in water mutually affected one another's volatility. (Author)
