Lead Acetate Test Paper
- Dip the test paper into the water for a few seconds, and remove.
- At approximately 1-3ppm, the white paper will start to turn grey. As the concentration increases, the color of the paper will turn darker up to 400ppm. If the Sulfide concentration is high (100 ppm+), the paper should turn black fast (within a few seconds). Lower concentrations will take a little longer. In very dilute concentrations, it is better to take a drop or two of solution and place it on the paper.
- You can also moisten the paper with distilled water and place in an area where Hydrogen Sulfide is thought to be present (an acetate buffer is not necessary).
Note: Lead Acetate test paper does not cross-react with thiols, thioketones or mercaptans: these produce a negative response.
WARNING: This product can expose you to Lead Acetate, which is known to the State of California to cause cancer. For more information, visit www.P65Warnings.ca.gov.

Fact Sheet
Technical Papers from the Bureau of Standards
Is it recommended to dip the Lead Acetate test paper in distilled water before use?
The Lead Acetate paper detects the presence of sulfur. The strip works best when wet (when testing for sulfur gas – the gas absorbs into the wet paper) or dipped into a test solution. The sulfur will form a black precipitate with the lead, lead sulfide. In dilute solutions, the paper may turn grey, and not black. The detection limit in solution is 5 ppm.
When testing gas, there are several keys…
- The paper must be moist to facilitate absorption of the Sulfide gas and formation of sulfide ions that would then react with the lead on the paper.
- The paper cannot be “too wet”. The Lead Acetate impregnated in the paper is not “bound” to the paper and can be washed away if the paper “wetted” with too much water.
- The intensity of the reaction of the moist lead acetate paper and sulfide gas will depend on how much gas is getting exposed to the paper and how long the moist test paper is exposed to the gas. The more intense the gas and the longer the exposure, the better the detection.
