Lead acetate paper is a filter paper impregnated with lead acetate. The test is particularly suitable for high range applications in disinfectant solutions which are for example used in food and beverage industry and animal farms. It reacts with hydrogen sulfide changing color from white to brown-black. Lead acetate reacts with Hydrogen sulfide to yield black lead sulfide. In the presence of low hydrogen sulfide concentrations, however, the white paper assumes a brown color only. Instruction Sheet (pdf) Color reaction: white → brown-black Scope of delivery: 1 reel of 5 m length and 7 mm width |

The test paper allows the quick and easy detection of hydrogen sulphide. This gas occurs in the processing of raw oil. It is toxic even in low concentrations. Therefore, critical points are carefully checked. Sulphide containing solutions also give a positive reaction. Lead acetate is toxic and the test paper needs to be declared as hazardous. The technically equivalent Sulphide test paper (REF 90761) is a non-toxic and safe alternative.
