HYDROGEN SULFIDE MEASUREMENT AND DETECTION
As the name implies, hydrogen sulfide analyzers using the lead acetate detector are based on the reaction of hydrogen sulfide with lead acetate. The initially white lead acetate turns brown when exposed to hydrogen sulfide in the presence of water. The greater the amount of H 2 S in the sample, the darker the stain that forms on the tape.

Measurement of iron and lead sulfide solubility below 100 ...
Nov 15, 2018· 1. Introduction. The presence of zinc, lead, and iron plus H 2 S can trigger the formation of scale materials such as Zinc Sulfide (ZnS), Lead Sulfide (PbS), and Iron Sulfide (FeS). The solubility of these compounds is very low compared to other scaling materials such as CaCO 3 or BaSO 2 S can be naturally occurring or be the result of sulfatereducing bacteria [].

Decreased Synthesis Costs and Waste Product Toxicity for ...
Use of lead sulfide (PbS) colloidal quantum dot (QD) films as photoactive layers in photovoltaic (PV) devices typically requires replacement of native QD ligands with lead‐based capping ligands (, PbX 2, X = Br, I) for the best‐performing QD PVs. This ligand replacement process often requires additional solvents and toxic reagents.

Uses of Lead | Lead Deposits and Resources
Lead commonly occurs in mineral deposits along with other base metals, such as copper and zinc. Lead deposits are broadly classified on the basis of how they are formed. Lead is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).
