Elements and the chemical properties of coconut shell activated carbon, coconut shell activated carbon is widely used in water treatment in many areas, but many customers elements and chemical characteristics of coconut shell activated carbon is not very understanding, below we jin hao of coconut shell activated carbon, summed up the following nine clear concise expounds the coconut shell activated carbon.
1. Coconut shell activated carbon is composed of amorphous carbon and different amounts of ash, and the carbon element station is 70 percent to 95 percent.
2, coconut shell activated carbon: there are two elements in a is oxygen and hydrogen, majority is not completely in the production process and carbide residue in coconut shell activated carbon, and in the process of activation by chemical bonds.
Two is ash, coconut shell activated carbon is different, the ash content is different.
3. Oxygen and hydrogen in coconut shell activated carbon, one is the formation of heterocyclic compounds into the inner layer of carbon atoms, and the second is the formation of surface oxides in the microcrystalline end.
The surface oxides of the microcrystalline end of the coconut shell activated carbon are formed by the combination of covalent bond unsaturated with other elements.
The surface oxide of the microcrystalline end is often a complex of several oxides.
5. Coconut shell activated carbon is originally non-polar, and it has a certain weak polarity due to the formation of oxides on the surface of the microcrystalline end, and has certain chemical adsorption and chemical physical adsorption function.
6. The properties of microcrystalline surface oxide complexes directly affect the adsorption properties and adsorption capacity of coconut shell activated carbon.
7. Microcrystalline surface oxides, the simplest of which are carbon monoxide complex and carbon dioxide complex.
Microcrystalline surface oxide complex, which is both basic and acidic.
The adsorption properties and adsorption capacity of coconut shell activated carbon have different effects.
The oxide complex of the actual coconut shell activated carbon on the microcrystalline surface is often both alkaline and acidic, but the dominant role is different.
9. Ash in coconut shell activated carbon, its composition is due to different species of coconut shell activated carbon.
The ash content in coconut shell activated carbon has a catalytic effect on the adsorption of some electrolytes in the aqueous solution of coconut shell activated carbon.
