At 33 ?? or far more easily weathered dry air, moist air deliquescence. Technique 1. sodium sulfate dissolved in the soda ash, and (generated by burning sulfur) of sulfur dioxide reacts with sodium sulfite, then add boiling sulfur reactions, filtration, concentration, crystallization, obtained sodium thiosulfate. Na2CO3 SO2 == Na2SO3 CO2 Na2SO3 S 5 H2O == Na2S2O3.5H2O 2. Evaporation residue strategy utilizing sodium sulfide and barium sulfide in wastewater emissions of sulfur dioxide and sulfur reactions, the sulfur absorption,moncler polo shirt, evaporation, crystallization, obtained sodium thiosulfate. 2Na2S Na2CO3 4 SO2 == 3Na2S2O3 CO2 3. Oxide, sodium sulfite and recrystallization from the including sodium sulfide, sodium sulfite and caustic soda flake by adding sulfur oxidation; sodium bisulfite and sulfur and by recrystallization of crude sodium thiosulfate sodium thiosulfate from the three mixed, concentrated, crystal, obtained sodium thiosulfate. 2Na2S 2 S 3 O2 == 2Na2S2O3 Na2SO3 S == Na2S2O3 four. Recrystallization the crude crystals of sodium thiosulfate remedy (or crude sodium thiosulfate remedy), the impurity, concentration, crystallization, obtained sodium thiosulfate. 1. Arsenic use alkaline cleaning gas by-product coke oven gas desulfurization process of arsenic leftover soda (such as Na2S2O3), by suction, concentrated, crystallized, obtained sodium thiosulfate. Packaging sacks, woven glass or wooden packaging, liner bags. Bag (barrel) net weight 25 kg or 50 kg. Storage: Store in a cool and dry warehouse. Transport will need to stay away from the sun, rain. Not with acids, oxidizers had been stored or transported. Containers must be sealed to stop moisture melt. For example packaging moisture, indicating the contents from the deliquescence role has to be packaged separately and dry stacked. Not stored inside the open air, to step up treatment of wet packing. Sand can be put out fire with water. Detoxification or plastic bottle 500 g / bottle, bottled in black or white. It could be the remedy mercuric chloride poisoning, cyanide poisoning and acute cyanide poisoning, illness progression is rapid, it should be against the clock to rescue of acute poisoning, stress antidote in situ applications. 1. Oral poisoning, gastric lavage can 1:2000 potassium permanganate answer, and to stimulate the posterior wall of the throat to induce vomiting induced by gastric lavage 2. Inhalation poisoning ought to be right away evacuated, move to fresh air, well-ventilated place to rest three. Use of amyl nitrite into a handkerchief following crushing 1-2 branch, on the nose and mouth before inhalation poisoning, every single two minutes, as soon as each and every 5-6 times four. Symptomatic treatment. Cycle occurs, respiratory failure were given tonic, vasopressors, respiratory stimulants, oxygen, artificial respiration, and so on.; skin burns, obtainable potassium permanganate remedy, rinse, then wash having a remedy of ammonium sulfide 5. Following the scene by initial aid, might be quickly sent to hospital for therapy, need to not be delayed. Nitrite ?C sodium thiosulfate therapy: detoxification mechanisms: methemoglobin nitrite formation agent including enable the rapid formation of hemoglobin to methemoglobin, which ferric ion with the body of totally free or with cytochrome oxidase combine to form an unstable mixture of cyano methemoglobin cyanide, leaving the ELISA was inhibited. Methemoglobin cyanide solution in a few minutes far from the cyanide ion can be, so be quick to give for the agent for example sodium thiosulfate sulfur, cyanide ions into the low toxicity of thiocyanate and excreted.
