文摘

The surface tensions of DEAE and amine-DEAE aqueous solutions were measured. The experiments were modelled satisfactorily by using a thermodynamic equation. MEA and PZ have close ability to decrease the solution surface tension. The temperature dependence of the surface tension was illustrated. The effects of the mass fractions of amines and DEAE were demonstrated.
