For example, other metal sulfides
, such as zinc sulfide
, could also interfere with the resin oxidation, etc.
is a kind of sea-bed deposit containing copper, zinc and precious metals such as gold and silver.
Though nZVI has been demonstrated to effectively remove sulfide
species in the bench scale, the feasibility of nZVI for field applications of sulfide
removal has not yet been investigated.
Formation and characterization of conductive thin layers of copper sulfide
([Cu.sub.x]S) on the surface of polyethylene and polyamide by the use of higher polythionic acids.
Benthic diatoms and sulfide
fluctuations: upper basin of Pettaquamscutt River, Rhode Island.
If sulfate-consuming bacteria had created the Australian sulfides
, the ratio of sulfur-33 to sulfur-32 in the rocks should have been lower than normal.
oxidation and re-formation during incubation experiments
Finally, the types of sulfides
most often found in coal mines may be more reactive than the types found in hardrock mines.
Dilute HCI is mixed with a given wet weight or volume of sediment sample to liberate gaseous [H.sub.2]S from acid-soluble metal sulfides
(principally FeS) which may be present.
With a single unit process, catalytic/adsorptive carbon can now more effectively remove chloramine and additionally remove hydrogen sulfide
from potable process water while continuing to remove free chlorine and other taste and odor chemicals.
