MAKING & TESTING CDS USING
THE JIM HUMBLE METHOD
5900 ppm chlorine dioxide this time
Please note: it is not necessary to be as elaborate as I have been here, just do what Jim says and you will have potent CDS!
Today I made a batch of CDS trying to follow Jim's instructions exactly, and I took ppm measurements of the chlorine dioxide in the CDS. This is by far the most potent CDS I have made to date, and I highly recommend anyone starting to make CDS, make it according to Jim's instructions first, so you know what good CDS is like.
The only thing I did not have was baby bottles, which will arrive in 2 days. Instead, I used a 2 oz. brown dropper bottle for the reaction chamber and a 12 oz coke bottle for the receiving chamber. I used the stiff 1/4" polyethylene tubing cut on a slant that looks just like the tubing in Jim's video (original video has been removed; current Jim Humble video is dated 12/26/11) and that is sold in hardware stores. I used a one-hole black rubber stopper on the 2 oz brown bottle and no top at all on the coke bottle, as in Jim's video.
Ingredients:
1 oz. MMS1
1 oz. 50% citric acid
8 oz. cold distilled water
ice & water
Materials:
2 oz. brown dropper bottle
12 oz. coke bottle
1-hole rubber stopper
18" of stiff 1/4" polyethylene tubing
electric hot plate
pyrex pot for hot plate
thermometer
small funnel
bucket of ice water
0-500 ppm chlorine dioxide test strips
graduated cylinders to measure liquids
oral syringe to measure 1 ml (get at drug store)
Useful measurements: (referencing U.S. cups)
1 oz. = 1/8 cup = 30 ml
2 oz. = 1/4 cup = 59 ml
8 oz. = 1 cup = 237 ml
1 teaspoon = 5 ml
1/4 teaspoon = 1.25 ml
Procedure to make CDS:
I followed Jim's video instructions. Measured out 8 oz. of cold distilled water from the refrigerator into the 12 oz. coke bottle and put it into a small bucket with water and lots of ice. Added more ice a couple times during the 2 hour process.
Measured 1 oz. of MMS and using a plastic funnel put it into the 2 oz. brown dropper bottle. Measured 1 oz. of 50% citric acid and put it into the brown dropper bottle. Brown dropper bottle is full nearly to the top.
Put 1-hole rubber stopper, into which one end of the 1/4" polyethylene tubing had been inserted, into top of brown bottle, and put it into the pyrex pot on the hot plate, and turned hot plate onto low setting. Put other end of 1/4" tubing into the coke bottle, resting it on the bottom of the bottle, in the bucket of ice water.
Had thermometer installed on pyrex pot to watch the temperature. A couple times it got up to 180 degrees when the burner cycled on. Tried to keep it between 150-160 degrees most of the time. It was still bubbling just a little even after 2 hours but I stopped at that point and then tested the CDS with the test strips.
Procedure to test CDS for ppm chlorine dioxide:
Once I had the 8 oz. of CDS, I removed 2 oz. to a shot glass and suctioned up 3 ml into an oral syringe. I used graduated cylinders to measure 3 portions of 2 oz. of cold distilled water. I put 2 oz of distilled water into a 1 cup pyrex measuring glass and then put 1 ml of the CDS into that and stirred it well. Then I took a 0-500 ppm chlorine dioxide test strip, dipped it for 2 seconds, waited 10 seconds and took the reading. The color closely matched the 100 ppm color on the chart.
I then added another 2 oz. of the distilled water to the existing 2 oz. with the 1 ml CDS that I had just tested. So now I have 4 oz. of distilled water and 1 ml of CDS. I followed the test procedure again with a new strip and the color matched the 50 ppm color on the chart.
I then added another 2 oz. of the distilled water to the existing amount I had just tested. So now I have 6 oz. of distilled water and 1 ml of CDS. After following the test procedure, the color seemed closest to the 25 ppm color on the chart, however the difference between 25-50 ppm is not much, and it just seemed closer to 25 ppm.
I then repeated this whole 3 step process with another ml of the CDS, testing at 2 oz., 4 oz., and 6 oz. dilutions, and the readings were all identical to the prior tests as far as I could tell. I think the most reliable reading of all is the 100 ppm reading because that color seems to be easiest to clearly distinguish on the color chart for the test strips.
Therefore, based on the above, this CDS undiluted is running at 5900 ppm of chlorine dioxide, which is twice as strong as my prior batches using the forced air as I related here
