1.Ingredients: bentonite is a natural mineral, activated carbon is an artificial product, bentonite has advantages in this side. But activated carbon is made from natural waste, so it might be cheaper, too.
2.Treatment objects: bentonite can adsorb organic dyes and heavy metal ions, activated carbon is effective for organic matter, but basically ineffective for heavy metal.
3.Environmentally friendly: Although the reserves of bentonite are large, the mining of minerals will always have a negative impact on the environment. It is also a waste to use only as an adsorbent, while the preparation of activated carbon from waste reflects the concept of resource recycling.
4.Modification: bentonite can undergo some chemical modification to obtain other chemical properties and become a special adsorbent for certain pollutants. Activated carbon is chemically inert and difficult to undergo chemical modification.
5.Other factors: adsorption stability, desorption conditions, treatment equipment, etc.
