Modification of Polymer Inclusion Membranes has gotten much attention for diverse applications comparing to pure polymeric membranes. Regarding the alteration polymer blends, inclusion of nanoparticles filler and treatment techniques have been the primary research currently. However, this adjustment requires proper interaction understanding and the performance of materials utilized to set up the mixed matrix membrane before implementation in such essential applications. The membrane has a main drawback which is a lack of the long- term stability and strength. Thus, it is the uttermost important to increase the ability of the membrane by improving the properties. The objectives of this research are to fabricate and evaluate the physical, chemical and electrochemical properties of nanoparticles mixed matrix PIMs, to study the efficiency of the MG extraction using fabricated nanoparticles mixed matrix PIMs and to evaluate the kinetics of malachite green extraction in aqueous solution using fabricated nanoparticles mixed matrix PIMs. The membranes were fabricated through dry method phase inversion technique. Determined quantities of base polymer and carrier were dissolved in solvent under continuous magnetic stirring until a homogeneous solution was obtained. The membrane solution was then be spread on a flat glass plate using automatic film applicator to produce a membrane film. The performance evaluation of the membranes with different nanoparticles are being investigated using dye solution. The dye extraction of the fabricated membrane is affected by the presence of nanoparticles in the membrane. It has been prominent that PVC membrane is hydrophobic in nature. Due to the blending of hydrophilic nanoparticles, the hydrophilicity of the membrane surface being enhanced. Hence, the nanoparticles will innovate the structures of the supported mixed matrix flat sheet membrane. Apart from that, the other significance of this study is to help findings of MG extraction utilizing mixed matrix membrane and its behaviour.
