A study electrochemical properties of polystyrene blended inorganic precipitated membranes which include nickel tungstate, nickel carbonate, calcium tunstate and cadmium tungstate. Characterization of the membranes has been done by different sophisticated techniques such TG-DTA, XRD, SEM, FTIR, etc. The physicochemical properties of the membranes have been conducted.The effective fixed charge densities of the precipitated membranes have been calculated by using different methods suggested by various renowned membrane scientists.
