Abstract
This work reported an efficient electrochemical treatment for drinking water disinfection using a pyrolytic graphite electrode modified with ferrocenyl tethered polyamidoamine dendrimers–multiwalled carbon nanotubes–chitosan nanocomposite The influence parameters of electrochemical disinfection of Escherichia coli and Staphylococcus aureus such as applied potential and sterilization time were investigated Further investigation indicated that almost all 9999 of the initial bacteria were killed after applying a low potential of 04 V for 10 min During the electrochemical disinfection process the oxidized form of ferrocene was formed on electrode which played a key role in the disinfection towards E coli and S aureus Hence the proposed method may provide potential application for the disinfection of drinking water
