钠、硫代硫酸

This product can be used as a reducing agent, mordant, bleach, disinfectants, water purifying agents. Characters Sodium thiosulfate, also known as thiosulfate, which is monoclinic white crystalline powder, specific gravity 1.667, soluble in water, insoluble in alcohol, is heated in air decomposed into sodium oxide and sulfur dioxide. Burned in pure oxygen is generated sodium sulfate, sodium sulfide and sulfur. Industry indicators 1. Sodium thiosulfate /%: ≥ 99.0 2. Water insoluble /%: ≤ 0.01 3. Sulfide /%: ≤ 0.001 4. Iron /%: ≤ 0.002 5. pH, 6.5-9.5 Uses Mainly used in photographic industry for fixative. Dichromate tanning when a reducing agent, nitrogen exhaust neutralizer, mordant, straw and hair bleach, and dechlorination of pulp bleaching agent. Also used for tetraethyl lead, dyes intermediates manufacturing and silver ore raised. In addition, for the chemical industry, electroplating industry, reducing agent, water purifying agent works. In the textile industry for bleaching cotton after dechlorination agent, sulfur dyeing wool fabric dye, indigo dye anti-white agents, pulp dechlorination agent, the pharmaceutical industry as detergents, disinfectants and bleaching agents. Method Sodium thiosulfate dehydration. By the sodium thiosulfate pentahydrate was dissolved, filtered, concentrated, dehydrated, prepared anhydrous sodium thiosulfate. Packaging Lined with PVC plastic bag or plastic woven bag, net weight 40 kg. Storage Should be stored in a cool and dry warehouse. Dark, sealed, transport should avoid exposure, humidity, rain. Not with acid and oxidant were mixed reservoir operation. Containers must be sealed to prevent moisture melt. Such as packaging moisture, indicating the contents from the deliquescence effect has to be packaged separately stacked and drying. Can not be stored in the open air, on the wet packing to grasp handle. Sand when fire fighting water. Other Sodium thiosulfate solution of cyanide poisoning and can also be mercuric chloride poisoning. Acute cyanide poisoning in the rapid progression of the disease, 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 solution, and induce vomiting induced by pharyngeal stimulation gastric lavage; 2, inhalation poisoning should immediately withdraw from the scene, go to the air is fresh, well-ventilated place to rest; 3, with sub-acid, amyl nitrate, after 1-2 sticks smashed into a handkerchief, on the poisoning of the nose and mouth before inhalation, once every 2 minutes, once every 5-6 times; 4, symptomatic rescue. Occur, respiratory failure were given inotropic, vasopressor, respiratory stimulants, oxygen, artificial respiration, etc.; skin burns, potassium permanganate solution can be washed, and then washed with ammonium sulfide solution; 5, after the on-site first aid, shall immediately taken to the hospital for medical treatment must not delay. Nitrite - sodium thiosulfate therapy Detoxification mechanisms Methemoglobin forming agent such as nitrite, hemoglobin can rapidly form methemoglobin, which ferric ion with the body free of or with the combination of cytochrome oxidase in the formation of an unstable combination of cyano methemoglobin cyanide , Er Shi ELISA was inhibited. Methemoglobin cyanide solution in a few minutes from the cyanide ion can therefore be given for rapid sulfur agents such as sodium thiosulfate to cyanide ions into a low toxicity of thiocyanate and excreted.
