How to make 1 liter of 3000 ppm Chlorine Dioxide Solution (CDS)

Pure CDS = Chlorine Dioxide gas (ClO2) dissolved in distilled water (H2O)

Materials:

1 liter of distilled water.
75 ml of 22.4% sodium chlorite solution.
75 ml of 50% citric acid (or 10% hydrochloric acid).

How to make 22.4% sodium chlorite solution:

Dissolve 140 grams of sodium chlorite powder or flakes (containing 80% sodium chlorite) in 360 grams of distilled water.

Let the solution stand for 24 hours in a dark place and then filter it with a coffee filter.

How to make 50% citric acid:

Dissolve 300 grams of citric acid powder in 300 grams of distilled water.

How to make 10% hydrochloric acid:

Mix 100 ml of 35% hydrochloric acid with 250 ml of distilled water.
Mix 100 ml of 30% hydrochloric acid with 200 ml of distilled water.
Mix 100 ml of 20% hydrochloric acid with 100 ml of distilled water.

Precaution:

If distilled water is not available, use filtered water.

Do not make or store sodium chlorite solution, citric acid or hydrochloric acid using anything made of metal.

Storage:

Store the 3000 ppm CDS in a glass bottle. Put it in the refrigerator.

Usage:

To disinfect uncut fruits and vegetables, use 5 ml of 3000 ppm CDS for every 3 liters of water.
