Effect of temperature on adsorption of activated carbon

①The nature of activated carbon adsorbent

The larger the surface area, the stronger the adsorption capacity; Activated carbon is a non-polar molecule, which is easy to adsorb non-polar or very low-polar adsorbates; air purification activated carbon pellets The size of activated carbon adsorbent particles, the structure and distribution of pores, and surface chemical properties, etc. It also has a great influence on adsorption.

②The nature of adsorbate

Depends on its solubility, surface free energy, polarity, size and degree of unsaturation of adsorbate molecules, concentration of attached substances, etc.

③PH value of wastewater

Activated carbon generally has a higher adsorption rate in acidic solutions than in alkaline solutions. china activated carbon manufacturers  The pH value will affect the state and solubility of the adsorbate in the water, thereby affecting the adsorption effect.

④ Coexisting substances

When multiple adsorbates coexist, the adsorption capacity of activated carbon for a certain adsorbate is worse than when only the adsorbate is contained.

⑤Temperature

Temperature has little effect on the adsorption of activated carbon

⑥Contact time

It should be ensured that the activated carbon and the adsorbent have a certain contact time to make the adsorption close to equilibrium and make full use of the adsorption capacity.
