3 Method summary
The use of a volatile sample is formed between the body and the residue material differences between the physical and chemical properties of thermal stability and oxygen, etc.,
The samples were low-temperature heating evaporation, carbonation, high temperature burning, the sample body and the residue was completely separated, said the quality of the residue.
4 Safety Tips
Sulfuric acid or hydrochloric acid used in this test method is corrosive, be careful when operating! As splashed on the skin should immediately wash with water,
In severe cases should be treated immediately. This test method need to use high-temperature furnace, the operation must be careful to prevent burns.
5 General Provisions
This standard reagents and water, did not indicate when the other requirements, refer to analytically pure reagents and GB/T 6682-2008 stipulated three
Grade water.
6 Reagents
Hydrochloric acid solution was 6.1. 1 + 1.
6.2 sulfuric acid.
7 instruments and equipment
7.1 evaporation vessel. crucible or evaporating dish, made of platinum, quartz or ceramics.
