Abstract: The reverse microemulsion system of Span 80-Tween 80/liquid paraffin/acrylamide-H2O was prepared, and the effects of n-butanol，NaCl，NaAc were studied with the conductivity method.The stability of reverse microemulsion was reflected, and the information of its dynamic process was obtained by measuring its state changes continuously through testing its electronic conductivity by using electrochemistry.The results showed that the Span 80-Tween 80/liquid paraffin/acrylamide-H₂O system was most stable when the HLB value approached 7.5, and its stability was enhanced when 5.0% (mass) NaCl or 10% (mass) NaAc was added into this system.
