Electrolytic cell and method for removing bromine ions in drinking water by utilizing same

The invention relates to an electrolytic cell and a method for removing bromine ions in drinking water, and the electrolytic cell and method provided by the invention can be used for solving the technical problem of low removal rate in the existing method for removing bromate in drinking water. The inventive method comprises the following steps: adding deionized water into a cathode area 6 of the electrolytic cell while adding the drinking water to be treated into an anode area 5 of the electrolytic cell, wherein the bromate ion concentration of the drinking water to be treated is 1mg/L, and the pH value is adjusted to 7 by 0.1M HCl and NaOH; applying 8V of voltage through a power supply 7, controlling the current density at 10mA/cm<2> and the temperature of the electrolytic cell at 28 DEG C, and reacting for 600s, thus removing the bromine ions in the drinking water. The removal rate of the bromine ions is 82%-90% and the method is suitable for being used as a pretreatment technology for ...
