When discussing the practical topic of how to buy activated carbon, we first need to clarify the basic nature of activated carbon, its use and the wide range of products on the market, so as to make an economical and efficient choice. Activated carbon, with its strong adsorption capacity, is widely used in air purification, water purification, food decolorization, medical refining and other fields, and has become an indispensable environmental purification material in modern life.
Activated carbon is a specially treated carbon material with a porous structure, and these micropores can greatly increase its surface area, thereby enhancing the adsorption capacity of impurities in gases and liquids. According to the different raw materials and manufacturing processes, activated carbon can be divided into wood activated carbon, coal activated carbon, fruit shell activated carbon and other types, each type in the adsorption performance, physical form of each has its own advantages, choose the right activated carbon is very important.
By raw material source:
1. Wood activated carbon
2. Animal bone/blood activated charcoal
3. Mineral raw material activated carbon
4. Activated carbon from other raw materials
5. Recycled activated carbon
By manufacturing method
1. Chemical Activated carbon (chemical carbon)
2. Physical activated carbon (physical carbon)
3. Chemical-physical method or physical-chemical method activated carbon
According to appearance shape:
1. Powdered activated carbon
2. Charbon actif en granulés
3. Amorphous granule activated carbon
4. Cylindrical activated carbon
5. Spherical activated carbon
6. Activated carbon in other shapes
By aperture:
1. Large hole: aperture > 1000A°
2. Transition hole: aperture 20 ~ 1000A°
3. Micropores: The surface area of activated carbon with a aperture <20A° is mainly provided by micropores.
1. Wood activated carbon: activated carbon made of wood chips, charcoal, etc
2. Fruit shell activated carbon: activated carbon made of coconut shell, walnut shell, apricot shell, etc
3. Coal-based activated carbon: activated carbon made of lignite, peat, bituminous coal, anthracite, etc
4. Petroleum activated carbon: such as asphalt-based spherical activated carbon made of asphalt and other raw materials
5. Recycled carbon: recycled activated carbon with used waste carbon as raw material for reactivation
Before purchasing activated carbon, it is important to identify the use scenario and needs. Here are a few suggestions:
According to the application field selection: such as in the field of water purification, you can choose coal activated carbon or wood activated carbon. In the field of gold extraction, wood activated carbon can be selected. In the field of food processing, you can choose fruit shell activated carbon.
Select according to adsorption performance: Adsorption performance is one of the most important indicators of activated carbon, and its adsorption performance can be evaluated by comparing the specific surface area and pore volume of different types of activated carbon. In general, the larger the specific surface area, the better the adsorption performance.
Select according to particle size: The particle size of activated carbon will also affect its adsorption performance and use scenario. In general, the smaller the particle, the faster the adsorption rate, but it is also easy to cause blockage. The larger the particle, the slower the adsorption rate, but not easy to plug. Therefore, it is necessary to select the appropriate particle size according to the specific application scenario.
Selection according to cost: the price of different types of activated carbon varies greatly, and the appropriate activated carbon needs to be selected according to the actual application scenario and cost budget.
1. Iodine adsorption value: It is one of the important indicators to measure the adsorption capacity of activated carbon, the higher the value, the stronger the adsorption capacity.
2. Carbon tetrachloride adsorption rate: also reflects the adsorption performance of activated carbon, especially suitable for evaluating its performance in water treatment.
3. Ash and moisture content: High ash content may affect the adsorption effect, while excessive moisture content may reduce the actual use efficiency of activated carbon.
4. Particle size and pore size distribution: The appropriate particle size helps the activated carbon to distribute evenly in a specific space and improve the adsorption efficiency. The pore size distribution affects the adsorption capacity of different sized molecules.
Check before use: ensure that the activated carbon package is intact and not damaged to avoid contamination before use.
Regular replacement: The adsorption capacity of activated carbon is limited, and it needs to be replaced regularly according to the use situation to ensure the best purification effect.
Proper storage: Unopened activated carbon should be stored in a dry, ventilated place to avoid moisture affecting performance.
Combined use: For complex environments or high requirements, activated carbon can be considered in combination with other purification materials to achieve a better purification effect.
In summary, when choosing to use activated carbon, it is necessary to comprehensively consider the specific needs, treatment effect requirements and economic costs and other factors to achieve the best treatment effect and economic benefits.
