Who knows the quality index system of activated carbon? Help me, thanks!

Commonly used indicators of activated carbon, iodine value, carbon tetrachloride, methylene blue value, these three indicators are activated carbon for liquids, gases, decolorization, other like, moisture, strength, these are not too critical.

The strong adsorption power of activated carbon mainly depends on the iodine value, butane number, ash content, bulk weight and other values. The following is an explanation of the effect of each value of activated carbon on the adsorption force of activated carbon: 1

Iodine value (400-1300)The iodine value refers to the amount of iodine adsorbed by activated carbon in a 12 kl aqueous solution. The iodine value is associated with the pore surface area greater than 10a in diameter. Activated carbon** is high or low, and iodine value is one of the criteria for judging.

2.Butane number: Butane number refers to the amount of butane adsorbed per unit weight of activated carbon after saturated air and butane pass through the carbon bed at a specific temperature and pressure. 3.

Ash (6-16) There are two kinds of ash powder of activated carbon, one is the surface ash powder, and the other is the inner ash powder, and the ash powder of activated carbon usually refers to the inner ash powder. 4.Moisture (<5) Moisture is a measure of how much water carbon contains, i.e., the percentage of water adsorbed in activated carbon.

Commonly used performance indexes particle size, iodine adsorption value, methylene blue adsorption value, ash, moisture, strength, filling specific gravity, pH value, carbon tetrachloride adsorption rate...According to the material, it is classified as coconut shell charcoal, wood (sawdust) charcoal, coal charcoal, guoke charcoal, bamboo charcoal....According to the shape, it is classified as amorphous granular carbon, columnar carbon, powder carbon, spherical carbon, honeycomb carbon....The process, shape and material selected in the production of activated carbon are different, and the product performance indicators and uses are also different, and activated carbon is widely used in people's livelihood, industry, environmental protection and other fields, with a wide variety. Founded in 1996, Nanjing Mulinsen Carbon Industry Co., Ltd. is a professional activated carbon production enterprise integrating scientific research, development, production and sales. For 20 years, MLS has been focusing on the production of activated carbon, and has now developed into a subsidiary...
