Conventional water disinfection methods such as chlorination typically involve the generation of harmful disinfection byproducts and intensive chem. consumption. Emerging electroporation disinfection techniques using nanowire-enhanced local elec. fields inactivate microbes by damaging their outer structures without byproduct formation or chem. dosing. However, this phys.-based method suffers from a limited inactivation efficiency under high water flux due to an insufficient contact time. Herein, we integrate electrochlorination with nanowire-enhanced electroporation to achieve a synergistic flow-through process for efficient water disinfection targeting bacteria and viruses. Electroporation at the cathode induces sub-lethal damages on the microbial outer structures. Subsequently, electrogenerated active chlorine at the anode aggravates these electroporation-induced injuries to the level of lethal damage. This sequential flow-through disinfection system achieves complete disinfection (>6.0-log) under a very high water flux of 2.4 x 104 L/(m2 h) with an applied voltage of 2.0 V. This disinfection efficiency is 8 times faster than that of electroporation alone. Further, the specific energy consumption for the disinfection by this novel process is extremely low (8 x 10-4 kW h/m3). Our results demonstrate a promising method for rapid and energy-efficient water disinfection by coupling electroporation with electrochlorination to meet vital needs for pathogen elimination. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2COA of Formula: CuH2O2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. COA of Formula: CuH2O2
