In this study, copper nanoparticle immobilized on cation exchange resin (R-CuNPs) has been prepared using NaBH4 as a reducing agent at room temperature for removal of pathogenic bacteria from water. Characteristics of R-CuNPs were determined by XRD, SEM, EDS and FTIR. The results showed that copper nanoparticles with average particle size of 76.92 nm were obtained with crystalline structure in nature and were well distributed on the cation exchange resin surface. Antibacterial activity of R-CuNPs was tested using batch methods. The obtained results shown that Escherichia coli strain was completely removed after 30 min and the antibacterial effectiveness of R-CuNPs was dependant on the mass of copper on the resin. The average concentration of copper in the effluent from the column packed with 5 g R-CuNPs and at the flow rate of 2 ml/min was found to be 0.92 mg/l which is lower than the guideline value of WHO (2 mg/L). From the research results, it could be concluded that R-CuNPs can be used in disinfection in water treatment.
