“…Activated carbons are porous materials with adsorptive properties due to their porosity, high surface area, and surface chemistry (Rodríguez-Reinoso, 1997). Activated carbons are widely used as adsorbents of gases (such as H 2 S, SO x , and NO x ), vapors, dyes, and heavy metals (Aliabadi et al, 2012;Bandosz, 2008;Duan et al, 2012;Furtado et al, 2013;Lemus et al, 2012;Ma et al, 2012;Zhang et al, 2013;Zhu et al, 2012). However, there is increasing scientific interest about the use of activated carbon to adsorb CO 2 (An et al, 2011;Aroua et al, 2008;Guo et al, 2006;Redondas et al, 2012;Somy et al, 2009).…”

Adsorption methods are one of the current ways to reduce CO2 emissions. Taking this into account, sewage-sludge-based activated carbons were produced to study their CO2 adsorption capacity. Specifically, chemical activation with KOH and NaOH of previously pyrolyzed sewage sludge was carried out. The results obtained show that even with a low BET surface area, the adsorption capacity of these materials was comparable to that of a commercial activated carbon. As a consequence, the use of sewage-sludge-based activated carbons is a promising option for the capture of CO2 and an interesting application for this waste.

“…Sulphur dioxide is one of the main causes of acid rain which needs attention because it can be one of the serious global environmental problems. Adsorption of SO2 gas using activated carbon material has been carried out by many researchers [43,44]. Most of the production of activated carbon is carried out using chemical methods.…”

The use of organic waste as bio-sorbent has been carried out by many researchers in the world. Furthermore, the utilization of plants for treating wastewater is also commonly found in various environmental applications. Nevertheless, a review of the ability of banana plants (Musa spp.) as bio-sorbent to eliminate gaseous pollutants is rarely found and has not been fully understood. In this paper, lignocellulosic biomass from banana plants (bark, stem, leaves, peels, etc) was identified and reviewed. Sorption potential was discussed and taken from various literature which then evaluated to discuss the potential and ability of banana plants as sorbent material for treating gaseous pollutants. Assessment and measurement methods were also discussed to obtain the best sorbent in removing gaseous pollutants. This research was conducted by reviewing scientific articles that discussed the use of lignocellulosic materials derived from banana plants for absorbing various gases. Almost all articles described the manufacture of adsorbents from banana plants that were used to treat wastewater but not many researchers have tried to develop a commercially adsorbent for gas-shaped pollutants. This research is expected to provide essential information for the readers to develop advanced materials used to control environmental pollution especially gaseous pollutants.

“…[11][12][13] Adsorption techniques have shown great capabilities to remove the trace amounts of a wide variety of toxic substances. [14][15][16] Nevertheless, due to the small size of ammonia molecules, for most of the designed ammonia sorbents, weak retention besides intermolecular forces is an issue. Therefore, use of porous solid materials with highly reactive functional groups is recommended.…”

In this study, a novel adsorbent was developed based on nickel oxide, strontium oxide and zirconia oxide and was anchored onto graphene oxide to produce a heterogeneous nanocomposite (NiSr-ZrO 2 /GO) for efficient removal of ammonia from industrial wastewater. The proposed nanocomposite was characterized using FTIR, XRD, SEM, EDX, BET, and TEM techniques. Effects of changing important parameters on the ammonia adsorption such as pH, adsorbent dosage, contact time, and initial concentration of ammonia were investigated. Different models were conducted to study the kinetics and isotherms equilibrium data of the adsorption process. The results revealed that the adsorption kinetics was well-fitted to the second-order model. The equilibrium data were well fitted on Langmuir isotherm model with a maximum monolayer adsorption capacity of 181.81 mg g −1 (R 2 = 0.997). Adding metal-containing species to graphene oxide can favorably interact with ammonia.
