Coconut shell activated carbon is a very popular type of activated carbon. Some unscrupulous merchants in the market sell fake coconut shell activated carbon. So, how should we distinguish the authenticity of activated carbon? Let's take a look together!
Here are some simple methods to distinguish them:
1. Coconut shell activated carbon belongs to the category of fruit shell activated carbon. Its main characteristics are low density, light texture, and significantly lighter weight than coal based activated carbon. When the weight of activated carbon is the same, the volume of coconut shell activated carbon is generally larger than that of coal based activated carbon.
2. The shape of coconut shell activated carbon is generally in the form of broken particles and flakes, while the shape of columnar and spherical activated carbon formed is mostly coal based activated carbon.
3. Due to the low density and light texture of coconut shell activated carbon, it can be directly placed in water. Charcoal generally sinks faster, while coconut shell activated carbon floats in water for a longer time. As the adsorption of water molecules by activated carbon reaches saturation, the weight of coconut shell activated carbon will gradually sink to the bottom. When activated carbon sinks into the seabed, there will be a small bubble outside each activated carbon. Crystal clear, very interesting.
Coconut shell activated carbon is a small molecular pore structure. When activated carbon is placed in water, the air released when it adsorbs water molecules produces many very small bubbles (visible to the naked eye), which float densely on the water surface. Coal based activated carbon generally has a large molecular pore structure with large bubbles.
