Methods to produce chlorine dioxide solution increased storability and bactericidal activity

摘要

PURPOSE: A method for manufacturing chlorine dioxide liquid with improved storability and bactericidal activity is provided to produce sterilization compositions having good bactericidal activity of endospores. CONSTITUTION: A method for manufacturing chlorine dioxide liquid with improved storability and bactericidal activity includes a step for making organic acid liquid of which pH is adjusted to 4 ~ 6 by adding NaOH and a step for reacting the organic acid with sodium chlorite. The organic acid is acetic acid, citric acid or lactic acid. The organic acid liquid is the liquid diluted to 1-20 wt%. A reaction process is performed at a temperature of 20-30 C with 100-200 rpm.
