Performance and its influencing factors.
The results show that the incr

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.
https://www.yrdcarbon.com/products/activated-carbon/granular-activated-carbon.htmlBy 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 iodine adsorption value, methylene blue adsorption value, strength and BET specific surface area of GAC were 1020.04mGG, 225mg/g, 88.73% and 1486.48m2/g respectively.
The experimental results show that the impregnation ratio and carbon activation temperature have great effects on the adsorption performance of GAC, while the kneading temperature and impregnation ratio have great effects on the strength of GAC.Activated carbons with different specific surface area and pore structure were prepared by physical activation and chemical activation, changing carbonization and activation conditions.
The pore structure of activated carbon was analyzed by ASAP2020M aperture analyzer.
The surface structure characteristics of activated carbon and the pyrolysis process of biomass under different conditions were studied. The adsorption performance and yield of activated carbon prepared by two methods were discussed and compared.Can be prepared into a variety of solutions to facilitate the composite with other materials.
Raw material is a wide range of natural graphite meters, is prepared by industrial methods can be put into production.
