抄録

The removal of a small quantity of p-nonylphenyl poly (oxyethylene) ether (EO 10 moles) in water was studied by foam fractionation method.<BR>Air was bubbled through water at a constant flow rate (150cm3/min), and the adsorption of the surfactant on the (generated) bubble surface and its removal (effect) were measured.<BR>The results were as follows : <BR>1) The adsorption of the surfactant on the bubble surface was found to come to an equilibrium in about two or three seconds, and the adsorption isotherm was confirmed to be in good agreement with Langmuir equation.<BR>2) In the continuous foam fractionation at a constant air flow rate, the removal effect was better as the concentration of the fed liquid was lower and the feeding rate was smaller.
