Abstract
To clarify adsorption–equilibrium relationship at liquid–atmosphere interface, adsorption behavior of bisphenol-A (BPA) and diethyl phthalate (DEP) onto bubble surface was studied by using nonfoaming adsorptive bubble separation (NFBS) technique. The adsorption isotherms of BPA and DEP were obtained experimentally. The experimental results showed that adsorption equilibrium of BPA and DEP on bubble surface followed Langmuir's adsorption isotherm. Two adsorption parameters, the adsorption equilibrium constant and the saturated adsorption density on bubble surface could be determined and were 2.04 × 105 cm3/g and 1.35 × 10−8 g/cm2 for BPA and 9.41 × 104 cm3/g and 1.79 × 10−8 g/cm2 for DEP, respectively.
