“…Biomass can be converted into a wide variety of carbon-based materials such as biochar, carbon black, activated carbon, carbon nanotubes (CNTs), and GO via carbonization at 600–1200 °C as described in Figure 7 [ 80 ]. Carbonized materials can be treated and activated using different kinds of acids, alkalis, and gases listed in Table 4 .…”

Emerging Materials to Prepare Mixed Matrix Membranes for Pollutant Removal in Water

et al. 2021

Various pollutants of different sizes are directly (e.g., water-borne diseases) and indirectly (e.g., accumulation via trophic transfer) threatening our water health and safety. To cope with this matter, multifaceted approaches are required for advanced wastewater treatment more efficiently. Wastewater treatment using mixed matrix membranes (MMMs) could provide an excellent alternative since it could play two roles in pollutant removal by covering adsorption and size exclusion of water contaminants simultaneously. This paper provides an overview of the research progresses and trends on the emerging materials used to prepare MMMs for pollutant removal from water in the recent five years. The transition of the research trend was investigated, and the most preferred materials to prepare MMMs were weighed up based on the research trend. Various application examples where each emerging material was used have been introduced along with specific mechanisms underlying how the better performance was realized. Lastly, the perspective section addresses how to further improve the removal efficiency of pollutants in an aqueous phase, where we could find a niche to spot new materials to develop environmentally friendly MMMs, and where we could further apply MMMs.

“…The rapid development of synthetic dyes has efficiently promoted the industrial growth in applications such as the leather, paint, textile and other industries. However, the usage of large amounts of dyes has resulted in severe environmental issues due to the disposal of dye-containing wastewaters in aqueous systems [1][2][3]. Wastewater containing synthetic dyes reduces light penetration in receiving water bodies and thus affects the photosynthetic activities of aquatic flora, destroying the aqueous system, thereby badly affecting the food sources of aquatic organisms [4].…”

To remove the pollutant methylene blue (MB) from water, a sheet-like skeleton carbon derived from shaddock peels (SPACs) was prepared by NaOH activation followed by a calcination procedure under nitrogen protection in this study. Characterization results demonstrated that the as-prepared SPACs displayed a hierarchically porous structure assembled with a thin sheet-like carbon layer, and the surface area of SPAC-8 (activated by 8 g NaOH) was up to 782.2 m2/g. The as-prepared carbon material presented an ultra-fast and efficient adsorption capacity towards MB due to its macro-mesoporous structure, high surface area, and abundant functional groups. SPAC-8 showed ultrafast and efficient removal capacity for MB dye. Adsorption equilibrium was reached within 1 min with a removal efficiency of 99.6% at an initial concentration of 100 mg/g under batch adsorption model conditions. The maximum adsorption capacity for MB was up to 432.5 mg/g. A pseudo-second-order kinetic model and a Langmuir isotherm model described the adsorption process well, which suggested that adsorption rate depended on chemisorption and the adsorption process was controlled by a monolayer adsorption, respectively. Furthermore, column adsorption experiments showed that 96.58% of MB was removed after passing through a SPAC-8 packed column with a flow rate of 20 mL/min, initial concentration of 50 mg/L, and adsorbent dosage of 5 mg. The as-prepared adsorbent displays potential value in practical applications for dye removal due to its ultrafast and efficient adsorption capacity.

“…Carbon-based adsorbents possess exceptional adsorption capability, thus highly useful for removing contaminants from the environment; and in this area, sustainable biomass-derived carbon materials are especially interesting [14][15][16]. In this special collection, Hakkarainen et al (KTH, Sweden) [17] described free-standing threedimensional lignin-derived porous graphene oxide (GO)based nanocomposites with excellent adsorption capacity for heavy metal ions and cationic dyes (DOI: https:// doi.…”
