Lead acetate paper: Quick and easy determination of lead hydrogen sulphide. Features: • 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. • Sulfide containing solutions also give a positive reaction. • Lead acetate is toxic and the test paper needs to be declared as hazardous. • The technically equivalent Sulfid test paper is a non-toxic and safe alternative.
