 2.Use:

1) mainly used as fertilizer ammonium sulfate, applied to a variety of soil and crops.

2 )used in textile, leather, medicine and so on.

3 )consumption from the industrial ammonium sulfate ammonium sulfate dissolved in distilled water, except the addition of arsenic and heavy metals in solution purification agents, filtration, evaporation, cooling crystallization, centrifugal separation, drying. Used as food additives, as dough conditioner, yeast nutrients.

4 )used in biochemistry, common salt, salting, salting initially be upstream from the fermentation products of purified proteins.

 

3.Storage:

Handling Precautions: closed operation, local exhaust. The operator must go through specialized training, strict compliance with operating procedures. Proposed operators wear self-absorption filter respirators, wear chemical safety glasses, wear protective overalls on infiltration, wear rubber gloves. To avoid dust. Avoid contact with acids.

 

 

4.others:

Emergency treatment: isolation leakage polluted area, restricting access. Recommended emergency personnel wearing a dust mask (full cover), wearing protective clothing. If large spills, recycling or shipped to the collection With a clean shovel collection in a dry, clean, covered containers, transfer to a safe place waste disposal sites
