Abstract

BaCO₃ nanoparticles (NPs) (20 and 100nm) were prepared using poly(vinyl pyrrolidone) (PVP) as stabilizer. The prepared NPs showed high adsorption capacity for Mg²⁺ in presence of other cations (Na⁺, Ca²⁺ etc.). BaCO₃ nanoparticles embedded sulphonated poly(ether sulfone) (SPS) membranes were prepared, which showed Mg²⁺ retentive and cation selective properties. These membranes exhibited good thermal, mechanical, and chemical stabilities along with conductivity and ion-exchange capacity due to SPS matrix. Mg²⁺ retentive nature of these membranes was attributed to the embedded BaCO₃ NPs. Further, SPS-NPE membrane was assessed suitable for electro-separation process. Electrodialytic studies confirmed very high retention values for Mg²⁺ in comparison with Na⁺ and Ca²⁺. The energy consumption of proposed process suggested suitability of these membranes for separation/recovery of Mg²⁺ from natural water resources.
