In the present work, preparation of a liquid emulsion membrane was successfully accomplished with the use of hydrodynamic cavitation process. As-prepared liquid emulsion membrane was effectively applied in the separation of Co (II) ions from highly concentrated effluent. The effectiveness of separating Co (II) ions from wastewater was examined in relation to a number of parameters, including surfactant content, LEM formation time, treat ratio, and carrier concentration. The optimal process parameters for the preparation of liquid emulsion membrane using the hydrodynamic cavitation process were 6 min of emulsification time using a carrier and surfactant concentration of 1 and 4% (v/v), respectively, with 0.1 N concentration of NaOH in the internal phase. The optimized process conditions the separation efficiency of Co (II) was observed to be 94.41% from a highly concentrated aqueous feed solution after 2 min of extraction time by maintaining 400 rpm agitation speed in the separation process for a 1:05 liquid emulsion membrane to feed phase ratio. Furthermore, to achieve the highest Co (II) separation efficiency from wastewater, an artificial neural network model was applied to optimize the process parameters used in the liquid emulsion membrane preparation.
