ONCENTRATE
:
Since ClO
2
in concentrate is in a stabilized form, it must be "activated" before use, but this must be performed in a
well ventilated area. Activate Oxine by adding acid to lower the pH to below 5 pH. Activation can be verified by a
corresponding color change of the concentrate from clear to yellow/green. Any number of acids will activate the
stabilized ClO
2
, however, food grade Citric or Phosphoric acid is recommended for this application. Normally it
requires up to 200 grams of Citric Acid to activate one gallon of stabilized ClO
2
concentrate (up to 50 grams per
liter of stabilized ClO
2
concentrate).
Replacement chemicals for your Oxine Test Kits, with important details, are as follows:
o
0.00564N PAO (Phenylarsine Oxide)
o
0.2N Hydrochloric Acid. Add 16.6 ml Concentrated HCL (39%) to 800 ml water. Bring to
1,000 ml with water
o
10% Potassium Iodide. 100 g diluted to 1,000 ml with distilled water
The following are available for purchase from IDD:
o
Test kits
o
Replacement materials
o
Oxine in 1-, 5-, 30-, and 55-gallon containers
Storage:
• Concentrated ClO
2
should be stored in dry areas, away from acids. It may last for up to three
years under standard conditions
• Activated ClO
2
has a half-life of approximately 48 hours under standard conditions
• Activated ClO
2
can be added to cold water at 4,000 ppm and will have a half-life of
approximately two weeks under standard conditions
Automatic Activation Systems:
A series of low cost, hands free, automated activation systems are available to provide a continuous volume
of activated ClO
2
into a storage reservoir to be available as needed. These systems eliminate the need for
manual mixing, measuring, and dispensing.
