What is? Activated carbon Iodine value?

The iodine value of activated carbon is one of the indicators to evaluate the adsorption performance of activated carbon, which refers to the amount of iodine adsorbed by activated carbon per gram. Generally speaking, the higher the iodine value of activated carbon is, the stronger the adsorption capacity is, and the more suitable it is for purifying water, air, etc. to remove pollutants.

Basic difference between activated carbon iodine value 800 and 1000

Due to different adsorption capacity, the applicable range of activated carbon iodine value 800 and 1000 will also be different.

Generally speaking, the iodine value of activated carbon 800 is suitable for air and water purification in household or small places, which can filter out larger polluting particles and odors, but the purification effect of smaller particles and gases is relatively poor, which is not suitable for highly polluting environments such as chemical plants.

The iodine value of activated carbon 1000 is suitable for the purification of gas and water quality in highly polluted environments such as small and medium-sized chemical plants, printing and dyeing plants, and can better absorb and remove various organic steam, acid and alkali and other pollutants.

Comparison of other indicators

In addition to the basic index of activated carbon iodine value, there are also some other indexes that need to be considered, such as pore size, specific surface area, bulk density, etc. These indicators will affect the adsorption speed and adsorption range of activated carbon and other factors. Therefore, various factors need to be comprehensively considered when selecting activated carbon.

Generally speaking, the pore size of activated carbon with iodine value of 800 is smaller than that of activated carbon with iodine value of 1000, while the specific surface area and bulk density are larger. This means that the adsorption speed of activated carbon with iodine value of 800 is fast, but the adsorption range is relatively small, while the adsorption speed of activated carbon with iodine value of 1000 is relatively slow, but the adsorption range is wider, which can absorb more different kinds of harmful substances.

Selection under different needs

Based on the difference between the iodine values of 800 and 1000 of activated carbon and the factors of other indicators, it can be selected according to different needs.

For air and water purification in household or small places, activated carbon with iodine value of 800 can be selected, because the price is relatively affordable and the purification effect is relatively good.

For gas and water purification in the industrial field, it is recommended to select activated carbon with iodine value of 1000, because in a highly polluted environment, strong adsorption capacity and adsorption range are required to achieve better purification effect.
