Paper making industry: As the cooking agent for paper
Textile industry: For the reduction of synthetic fiber denitration and nitration as well as the mordant for cotton fabric dyeing
Pharmaceutical industry: For the production of febrifuge such as phenacetin
Others: For the production of sodium thiosulfate, sodium polysulfide and sodium bisulfide, ect
Storage and transportation conditions
Should be stored in a cool, well-ventilated area;
Keep away from ignition sources, heat and flame;
Packing encapsulation;
Should be divided with oxidants, acids, avoiding mixing storage;
Shouldn't be stored for a long time lest metamorphism;
Equipped with corresponding varieties and amount of fire-fighting equipment;
Storage area should be equipped with stuff to contain releases.
Harms
For health: It will decompose hydrogen sulfide and leads to hydrogen sulfide poisoning. It has corrosion effect to skin and eyes.
For environment: It will do harm to environment.
