Co-adsorption and interaction mechanism of cadmium and sulfamethazine onto activated carbon surface

Sorption and Desorption Performance of La3+/Bi3+ by Surface-Modified Activated Carbon for Potential Application in Medical 225ac/213bi Generators

“…The isotherms equations and relevant results are summarised in Supporting Information and Table S8. The sorption data of SNCA-150 toward La 3+ and Bi 3+ can were fitted well by the Freundlich model (R 2 = 0.9941 for La 3+ and R 2 = 0.9919 for Bi 3+ ) over the Langmuir model (R 2 = 0.9085 for La 3+ and R 2 = 0.9709 for Bi 3+ ) based upon correlation coefficients (R 2 ), indicating that sorption occurred on a heterogeneous surface [64,65]. The values of n (sorption intensity from Freundlich model: n = 3.665 for La 3+ and n = 2.452 for Bi 3+ ) within (1,10) and R L values (the Langmuir dimensionless separation factor: R L = (0.03, 0.34) for La 3+ and R L = (0.03, 0.31) for Bi 3+ ) within (0, 1) suggest that the sorption of La 3+ and Bi 3+ onto SNCA-150 was favourable [66].…”

“…The sorption isotherms, including the Langmuir and Freundlich models, were applied to fit the experimental sorption data (Fig. 8b and c) [64,65]. The isotherms equations and relevant results are summarised in Supporting Information and Table S8.…”

Adsorption and co-adsorption mechanisms of p-nitrophenol and Pb(ii) on magnetic carbon aerogel in water

“…A large surface area and a small aperture of adsorbents are the two most important requirements when designing and preparing adsorbents, which can contribute to high adsorption performance. Up to now, various adsorbents such as polyamine chelating resin, 6 activated carbon, 7 Na-montmorillonite, 8 Mauritanian clay 9 and struvite loaded diatomite 10 have been applied to remove the coexisting pollutants of heavy metal and organic compounds. However, these adsorbents suffer from low adsorption capacities or removal efficiencies, seeking new and more effective adsorbents is a continuous effort for many researchers.…”

Preparation of the Carbonized Zif−8@PAN Nanofiber Membrane for Cadmium Ion Adsorption

“…The pollutants in waste water containing heavy metal ions have entered and accumulated in drinking water resources and the soil [1,2], which not only affects the output of agricultural products, but also ultimately endangers human health through the food chain [3][4][5]. The existing methods used to remove heavy metal pollutions mainly include filtration [6], adsorption [7,8], membrane separation [9], ion exchange [10] and photocatalytic degradation [11]. Among them, the adsorption separation has been one of the most popular methods on account of its effectiveness and simplicity.…”
