Lead acetate paper
REF 907 44
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 907 61, page 42) is a non-toxic and safe alternative.
