- Sodium sulfide is the
name used to refer to the chemical compound Na2S but more commonly its
hydrate Na2S.9H2O. Both are a colorless water-soluble salts that give
strongly alkaline solutions.
- Sodium Sulfide is a
yellow to red solid, readily soluble in water, slightly soluble in
alcohol. It is a strong reducing agent and reacts with oxidants.
- Industrially Na2S is
produced by reduction of Na2SO4 with carbon, in the form of coal
- In the Kraft process
the fibres are liberated in the cooking plant by dissolving the lignin
and part of the hemicellulose in the cooking chemical solution (white
liquor), which contains sodium hydroxide and sodium sulphide as active
chemicals.
- Carbonation conversion
of aqueous sodium sulfide, i.e., with CO2 gas, is particularly favorable
since COa is readily available in the flue gas of carbothermic reduction
furnaces.
- The enzymatic treatment
of hides and skins can be considered as a cleaner technology only if the
amount of sodium sulphide is reduced substantially. However it is not
yet possible to use less than 1% of sodium sulphide for bovine hides.
- Sodium Sulfide
Pre-treatment Increases the Rate and Sensitivity of Silver Precipitation
onto 3,3’-diaminobenzidine(DAB). While looking for ways to maximize the
sensitivity of the silver enhancement, we observed that pre-treatment of
the DAB with sodium sulfide was very effective for this purpose
- Sodium Sulfide is used
to determine the phosphate in sugar cane juice and sodium sulphide is
found to be a very effective reducing agent but not commonly used for
phosphate determination.
- Sodium Sulfide is used
in water treatment as an oxygen scavenger agent, in the photographic
industry to protect developer solutions from oxidation, in textile
industry as a bleaching, as a desulfurizing and as a dechlorinating
agent and in leather trade for the sulfitization of tanning
extracts.
- Sodium Sulfide is used
in the production of rubber chemicals, sulfur dyes and other chemical
compounds.
- The main cost increase
in chemicals was due to the use of glucose which is 17% more expensive
than sodium sulphide
- During our religious
holiday of sacrifice, a leakage was detected on the retaining wall of
sodium sulphide pool towards the dry irrigation water channel, which is
located along the border of the plant.
- The oral ingestion of
alkali sulphides has been reported to cause nausea, vomiting and
epigastric pain, as well as irritate the mucous membranes; it has been
estimated that an oral dose of 10 to 15 g sodium sulphide would be fatal
to humans.
- The first factory is in
DaLian, produce solid sodium sulphides in low production. The contain of
it's production is Na2S 42%. Up to early of 40's. A Chemical Factory
started to produce solid sodium sulphides, the contain of Na2S is up to
52%.
