Tablets for the preparation of solutions of chlorine dioxide

Abstract

A tablet containing metal chlorite, a chlorine-releasing compound that releases chlorine when in contact with water, a solid acid source, a stearic acid metal salt, and a polymer-based disintegrating agent, and a stearic acid metal salt and a polymer-based disintegrant The total amount of the decomposing agent is 0.3 to 10% by weight relative to the whole tablet. Regardless of the scale of the facility to be treated, this tablet can generate chlorine dioxide at a sufficient concentration within a practical time, and has the advantages of being transported. Sufficient strength that does not cause breakage during handling, packaging, etc., and high productivity.

Description

technical field

[0001] The present invention relates to safe and simple preparation of an aqueous solution of chlorine dioxide used in various applications such as the removal of bacteria, viruses, malodorous substances, mold, and algae, the removal of unpleasant odors in water, and the removal of divalent metal ions in water tablet. Background technique

[0002] Chlorine dioxide is used as a powerful oxidizing agent in a wide range of applications, such as bleaching, sterilization, virus inactivation, algae killing, iron removal, manganese removal, and odor removal from water. However, chlorine dioxide having such a useful use has various problems in practical use.

[0003] Chlorine dioxide is explosive, toxic, and decomposable to light and heat in a gaseous state, so it cannot be directly transported in a gaseous state. In addition, even in the state of a chlorine dioxide solution having relatively higher stability than gas, it is difficult to maintain the concentration ...
