Überblick

Ammonium sulfide aqueous solution is a colorless to yellow liquid, with an odor of rotten eggs or ammonia. Can slowly react with water to generate flammable and toxic hydrogen sulfide gas. This reaction is much faster with acid. It may be irritating to skin, eyes and mucous membranes and may cause illness from skin absorption. It may burn and/or emit toxic fumes if heated to high temperatures.

Pharmakologische Informationen

Absorption, Distribution and Excretion · 2 Einträge

Alkali sulfides are rapidly absorbed from intestine. It is doubtful whether skin absorbs enough to cause systemic poisoning. The sulfide radical is in part excreted by lung & kidneys & metallic sulfides (as iron sulfide) by bowel, & in part oxidized to sulfate & thiosulfate & excreted by kidneys. /Sulfides/

First acid dissociation constant of hydrogen sulfide is about 1x10(-7) molar so that in body fluids dissociated & undissociated hydrogen sulfide exist in about equal proportions. Undissociated acid, however, penetrates biological membranes more rapidly than the hydrosulfide anion. /Hydrogen sulfide/

Separation process which combines liq membrane permeation & conventional steam stripping, effectively removed (NH4)2S from wastewater.

Refinery sour water containing 500-15000 ppm ammonium sulfide is mixed with hydrocarbon emulsion at top of stripping tower at 185 °F & steam is simultaneously passed into bottom of tower. Ammonia is removed with emulsion & hydrogen sulfide is stripped by steam.

Collect and remove with a broom into a large bucket. Dilute with water and neutralize with 6M hydrogen chloride. Drain into a sewer with sufficient water.

Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder.

Probable Routes of Human Exposure · 2 Einträge

According to the 2006 TSCA Inventory Update Reporting data, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use of diammonium sulfide is 1000; the data may be greatly underestimated(1).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 4,271 workers (1,482 of these were female) were potentially exposed to diammonium sulfide in the US(1). Occupational exposure to diammonium sulfide may occur through inhalation and dermal contact with this compound at workplaces where diammonium sulfide is produced or used. Use data indicate that the general population may be exposed to diammonium sulfide via ingestion of food and dermal contact with consumer products containing diammonium sulfide(SRC).

Antidote and Emergency Treatment · 5 Einträge

Emergency and supportive measures: NOTE: Rescuers should use self-contained breathing apparatus to prevent personal exposure. Maintain on open airway and assist ventilation if necessary. Administer high-flow humidified supplemental oxygen. Observe for several hours for delayed-onset chemical pneumonia or pulmonary edema. Treat coma, seizures, and hypotension if they occur. /Hydrogen sulfide/

Decontamination. Remove the victim from exposure and give supplemental oxygen, if available. /Hydrogen sulfide/

Enhanced elimination. There is no role for enhanced elimination procedures. Although hyperbaric oxygen therapy has been promoted for treatment of hydrogen sulfide poisoning, this is based on anecdotal cases, and there is no convincing rationale or scientific evidence for its effectiveness. /Hydrogen sulfide/

Inhalation of corrosive gases (eg, chlorine and ammonia) may cause upper respiratory tract injury, with stridor, hoarseness, wheezing, and noncardiogenic pulmonary edema. Pulmonary symptoms may be delayed after exposure to gases with low water solubility (eg, nitrogen dioxide and phosgene). /Caustic and corrosive agents/

VerwendenAmmonium sulfide solution is used occasionally in photographic developing, to apply patina to bronze, and in textile manufacturing. Ammonium sulfide is a very useful reagent in mineral analysis. Used in continuous culture of saccharomyces cerevisiae, useful in a double staining technique for visualization of astrocytes and microglia from brain sections and astroglial cell cultures. It plays an important role to modify the surface of low κ dielectric thin films. It is essential for molecular beam epitaxy regrowth. It is an unstable salt and acts as a selective reducing agent.
