| Abstract: | The influence of HLB values from Span80-Tween60 on the conductive behavior of inverse microemulsions containing acrylamide and/or acrylic acid has been investigated. The sharp increase of conductivity was observed when aqueous phase fraction was increased to some extent. The higher acrylamid concentration was in aqueous phase, the lower the aqueous phase fraction was for sharp conductivity increase. It was also found that the value of HLB around 7.48 was the optimum for preparing kerosine-water-AM(AA) inverse microemulsion, where the amount of emulsifier required was minimum and the aqueous phase fraction before sharp increase of conductivity was relatively higher. |
