The adsorption effect of activated carbon

Performance and its influencing factors.
The results show that the increase of adsorption time, pH and the amount of adsorbent will improve the adsorption effect of the modified activated carbon.
Based on the experimental data of adsorption of Zn2' and Cd by modified activated carbon and the adsorption principle, the mechanism and kinetic law of adsorption of heavy metal ions by modified activated carbon were studied.
The results show that the adsorption isotherms of Zn2' and Cd by modified activated carbon are in good agreement with the Langmuir and Freundlich adsorption models.
By fitting the kinetic equation of Zn2 adsorption with modified activated carbon, it was found that the first 30min of the adsorption reaction was in line with the Lagergren quasi-first-order reaction, and the second order reaction was in line with the latter.
The adsorption of Cd by modified activated carbon was a Lagergren quasi-first order reaction in the first 20 minutes.
The reaction after adsorption for 20min belongs to the Lagergren quasi-second order reaction.It solves the problem that graphene material is expensive and cannot enter the industrial application field without large-scale production.
It provides a foundation for the large-scale application of graphene.
Using the super conductivity and large specific surface area of graphene, the problem that the traditional activated carbon material used in the electrode can no longer improve the electric storage performance was solved.
