Preparation, electrochemical characterization and antibacterial study of polystyrene-based magnesium-strontium phosphate composite membrane

► The membrane was found to be crystalline in nature. ► Membrane potential of electrolytes followed the order LiCl > NaCl > KCl. ► The order of surface charge density was found to be LiCl < NaCl < KCl. ► The membrane show excellent results against E. coli and P. aeruginosa bacteria.
