Claim 0:
1. A method of manufacturing a chlorous acid aqueous solution, comprising the steps of:
(1) electrolyzing a salt to obtain a chlorate aqueous solution;
(2) generating a first reaction gas by adding at least one acid into the chlorate aqueous solution, wherein the first reaction gas comprises chlorine and chlorous acid; and
(3) generating a second reaction gas by adding hydrogen peroxide into the chlorate aqueous solution after the first reaction gas is no longer generated and capturing the second reaction gas by using a neutralization solution comprising hydrogen peroxide so as to obtain a chlorous acid aqueous solution, wherein the second reaction gas comprises chlorine dioxide and chlorous acid, and wherein only the second reaction gas captured by the neutralization solution is used for manufacturing the chlorous acid aqueous solution.
