“…They are therefore regarded as good adsorbents for the removal of heavy metal ions and other inorganic substances, as well as many organic compounds from liquid and gas phases. The production and study of nitrogen-containing activated carbon derived from ammonium humates was the objective of a recent paper [11]. Both surface chemistry and texture of carbons are affected by the nitrogen source and the type of oxygen functionalities pre-existing on the surface [18,19,61].…”

This work is a systematic review of the literature over the past decade of the application of activated carbon (microporous or mesoporous) as adsorbents for the removal of heavy metals, focusing especially on lead (Pb) and arsenic (As) ions from the aqueous phase. Classical examples from our lab are also given. Activated carbon is known to provide a high surface area for adsorption. Generally, surface modification is typically required, such as oxidation, treatment with ammonia or even impregnation with ferric ion, etc. and the adsorbent material may originate from various sources. The pristine materials, after modification and those after batch-wise adsorption, were characterized by available techniques (BET analysis, Fourier transform infrared spectroscopy, scanning electron microscopy, thermal analyses, X-ray photoelectron spectroscopy). Adsorption isotherms, thermodynamics and kinetics of the process are also discussed. Selected studies from the literature are examined in comparison with other adsorbents. The role of chemistry in the metals adsorption/removal was investigated.

“…A lot of porous materials, such as zeolites (Cavenati et al, 2004;Su et al, 2010), activated alumina (Luebke et al, 2006;Carreon et al, 2008), metal organic frameworks (MOFs) (Belmabkhout et al, 2009;Xiang et al, 2010) and carbonaceous materials (Przepiórski et al, 2004;Lu et al, 2008;Budaeva et al, 2010;Palmer et al, 2011;Lei et al, 2014) have been utilized in gas adsorption/separation processes. Recently, there is a lot of interest in utilizing CNTs for CO 2 adsorption due to their distinctive chemical and physical properties, high thermal and chemical stability and also the reversible nature of the CO 2 adsorption process upon increasing the temperature (Su et al, 2009;Shen et al, 2010;Khoerunnisa et al, 2014;Wang et al, 2016).…”

In order to improve the adsorption capacity and selectivity of CO 2 /CH 4 and CO 2 /N 2 , we have functionalized multi-walled carbon nanotubes (MWCNT) with 3-aminopropyltriethoxysilane (APTES). The functionalized MWCNT was characterized by Fourier transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDX) and BET analysis. CO 2 , CH 4 and N 2 adsorption at two different temperatures and P < 5 bar on the functionalized MWCNTs was investigated by the volumetric method. The selectivity of the functionalized MWCNTs for CO 2 /CH 4 and CO 2 /N 2 was studied and compared with MWCNTs. The functionalized MWCNTs show higher adsorption capacity of CO 2 and selectivity of CO 2 /CH 4 and CO 2 /N 2 in comparison with the MWCNTs at different pressures. The highest CO 2 /CH 4 and CO 2 /N 2 selectivities for the functionalized MWCNTs were 6.78 and 26.14, respectively, at a pressure of 0.2 bar and at 298 K. Two of the most common adsorption models, the Langmuir and Sips isotherms, were used to correlate the experimental data of CO 2 and CH 4 adsorption on the adsorbents. The results confirm that the functionalized MWCNTs are promising materials for the separation and purification of gases.
