In this study, the stability of Liquid Surfactant Membrane (LSM) is investigated for use in the extraction of toxic dyes. The LSM emulsion is prepared using Span80 as a surfactant, tridodecylamine (TDA) as transporter and sulfuric acid as internal phase. Various parameters, i.e. surfactant, transporter and internal phase concentrations, stirring and emulsification speeds, membrane phase to internal phase volume and treatment ratios, emulsification time as well as diluent type, are all examined in relation to emulsion stability. Stability tests are performed using the tracer method, as well as rheological and particle size analyses. Resultant optimal parameters using tracer method are: surfactant concentration: 10% (w/w); transporter concentration: 1% (w/w), internal phase concentration: 1N, stirring speed: 200rpm, emulsification speed: 20000rpm; volume ratio of organic phase to internal phase: 1/1, treatment ratio: 1/10, emulsification time: 5min; and diluent type is cyclooctane. These findings are confirmed by rheological and particle size analysis.
