The extraction of heavy metal ions in tannery effluent by nanoemulsion liquid membranes (NELMs) was studied. The liquid membrane phase of the NELM consisted of Aliquat336 as carrier, Span 80 as surfactant, neem oil as diluent, graphene & ZnO as stablising agent and sodium hydroxide solution as internal phase. The sample and extracted membrane phase was characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM) and Raman Spectroscopy. Optimization for several parameters such as pH, carrier concentration, surfactant concentrati...

Optimization for several parameters such as pH, carrier concentration, surfactant concentration, agitation speed, initial feed concentration, Extraction time, stripping ratio and M/S ratio was done and the highest extraction of heavy metals was analysed.
