This paper introduces a proof of concept that liquid membrane technology that has always been used as a separation technique, can also be extended for the generation of value added products in its downstream side. It is possible to generate cadmium sulphide nanoparticles in the stripping phase of liquid membrane separation unit which have wide industrial application such as solar and photovoltaic cells. The process parameters such as concentration of cadmium salt and pH in feed phase, concentration of strippant, concentration of extractant/carrier agent, etc. were optimised leading to maximum production of CdS nanoparicles in the stripping phase. The characterisation of CdS nanoparticles were carried out using TEM, FESEM-EDX, FT-IR, XRD and SAED. The nanosize and nanocrystalline nature of the CdS particles were established.
