The nanocomposite exhibited an excellent ion exchange capacity of 1.20 meq g −1 in addition to high thermal stability. The polymeric-inorganic nanocomposite ion exchanger was characterized by Fourier transform infrared (FTIR), XRD, SEM, and TEM studies. The DC conductivity of PANI/ZSWP was also investigated. The nanocomposite ion exchanger was found to be highly selective for Cu 2+ ions with a distribution coefficient value of 650 mL/g. The analytical applications of the material were explored by achieving selective separations of Cu 2+ and Ca 2+ ions from a synthetic mixture of Cu

X-ray diffraction, transmission electron microscopy, thermogravimetric analysis, and Fourier transform infra red techniques were used to characterize CdO nanoparticles. The average particle sizes of CdO nanoparticles were found to be $14 nm. The polarity of the BSA capped CdO nanoparticles was determined using gel electrophoresis technique. The synthesized CdO nanoparticles were used as photocatalyst for methylene blue degradation. The photodegrdation of methylene blue was optimized under different reaction conditions such as catalyst loading, dye concentration, temperature, and pH. Methylene blue dye was completely decolorized in 70 min of irradiation time. CdO nanoparticles were effectively used as antibacterial agent to inhibit the growth of Escherichia coli bacteria.
