Adsorbents for Mercury Vapour Recovery in Demercuration Technology
Abstract
Various adsorbents, including iodides and sulphides of some metals and modified carbon materials, were synthesized and their ability to recover mercury was studied. Our results showed that copper sulphide [dynamic capacity (DC) of 36 mg/g for mercury vapour], the active form of manganese dioxide (DC of 28 mg/g) and modified carbon adsorbents were promising demercuration agents. The DC of the best demercuration agents (MNCS–O–Cl–I) can be as much as 125 mg/g.
