    摘要:New water disinfection technologies should be developed because current methods usually produce disinfection by-products and are expensive. Here, we demonstrated the use of a contact-active activated carbon electrode functionalized by quaternary ammonium compound for capacitive deionization disinfection (CDID) at a contaminant concentration of 104 CFU/mL. The effects of cell voltage, flow rate, and ion concentration on the disinfection performance of CDID electrode were investigated. The electrode can kill 99% of Escherichia coli or Pseudomonas aeruginosa (with a concentration of 104 CFU/mL) at a relatively low cell voltage (1.2 V) and a relatively high flow rate (5 mL/min). The damage on cell membranes was proved to be the killing mechanism. Furthermore, the CDID system exhibited high cyclic stability and its kill rate was maintained approximately 90% after five regeneration cycles. Thus, CDID electrode presented in this work has promising application prospect in water disinfection.
