“…In addition to hydrophobicity, other factors such as porosity, surface area, etc., also play an important role in determining the oil adsorption capacity of biochar. Biochar with high porosity has higher oil removal capacity because the oil is trapped between the porous arrays [ 95 , 151 ]. Biomass with a high lignin content results in biochar that is more hydrophobic and amorphous.…”

The current water crisis necessitates the development of new materials for wastewater treatment. A variety of nanomaterials are continuously being investigated for their potential as adsorbents for environmental remediation. Researchers intend to develop a low-cost, simple, and sustainable material that can cater to removal of pollutants. Biochar derived from biowaste is a potential candidate for the existing problem of water pollution. The review focuses on the various aspects of biochar, such as its sources, preparation methods, mechanism, applications for wastewater treatment, and its regeneration. Compared with other adsorbents, biochar is considered as an environmentally friendly, sustainable, and cost-effective substitute for waste management, climate protection, soil improvement, wastewater treatment, etc. The special properties of biochar such as porosity, surface area, surface charge, and functional groups can be easily modified by various chemical methods, resulting in improved adsorption properties. Therefore, in view of the increasing environmental pollution and the problems encountered by researchers in treating pollutants, biochar is of great importance. This review also highlights the challenges and prospective areas that can be explored and studied in more detail in the future.

“…Moreover, research on oil spill cleanup using sorbents and nanoparticle technology has shown a continuous growth in the last decade . Different types of carbon materials have been studied as oil sorbents, such as carbon nanotubes, graphene‐based sorbents, carbon aerogels, graphite, carbon nanoparticles, active carbon, and biochar . Still, two of the great challenges regarding some of these sorbents are a one‐step facile production and high sorption capacities …”

Oil spills in water cause environmental and economic disasters. Herein, a superhydrophobic and oleophilic carbonaceous nanosponge (CN) with high adsorption capacity for selective oil removal from water was developed. It was grown by plasma polymerization of commercial acetylene in a radio frequency glow discharge (RFGD), a single‐step, scalable technique. The CN is a porous network of spherical nanoparticles with a broad pore size distribution. It adsorbs 33 times its own weight of light crude oil, with null water adsorption in shaking conditions (ASTM F726‐12). Because the CN could be used under sunlight exposure, the effect of UV light irradiation was studied. Potential applications of the CN arise, as it can be deposited on many substrates and change their wetting properties.

“…One of the promising technologies for FOG treatment is adsorption. A cost-effective and straightforward adsorption method with highly effective adsorption capacity is required to remove FOG from the wastewater (Kandanelli et al, 2018;Lam et al, 2018;Sohaimi and Ngadi, 2016). Carbonaceous materials are commonly used adsorbents in wastewater treatment.…”

Utilization of rain tree (Samanea saman) residue as modified adsorbent to treat oil and grease in canteen wastewater

The utilization of waste materials�as adsorbent precursors is gaining intention to treat fats, oils, and greases (FOG), especially in wastewater treatment. Tree residue, an abundant waste, provides a potential feedstock to be converted into valuable materials. This research aimed to develop modified adsorbent prepared from rain tree�(Samanea saman)�residue for FOG treatment. The synthesis process of modified adsorbent�was conducted by chemical pretreatment using different chemical agents (i.e., NaOH, ZnCl2, and H3PO4?). The pre-treated twigs and leaves (1:4 ratio)�were continued by pyrolysis process at different temperatures (i.e., 350, 550, and 750oC) using a heating rate of 10oC min-1�for 2 h. A batch sorption screening test was initially conducted for removing FOG from synthetic oily wastewater, and the ANOVA was employed to define the best-modified adsorbent among treatments. The result confirmed that modified adsorbent by H3PO4-treated and produced at 350oC had the highest net efficiency of FOG removal, with a yield and removal percentage of 55.87?1.40 and 79.77?1.17%, respectively. The adsorption studies of the best-modified�indicated that the pseudo-second-order kinetic and Langmuir isotherm models were well-fitted to the experiment data. The maximum adsorption capacity of FOG was found to be 6.89 mg g-1. Fourier transform infrared spectroscopy (FTIR) result�exhibits the present carbonyls, hydroxyls, and aliphatic groups. Scanning Electron Microscope (SEM) image showed the porous structure on the surface. The subsequent identification of the best-modified adsorbent�was carried out by fixed-bed column test and performed�optimum condition�for canteen wastewater treatment by�setting 10 cm bed height and flow rate 5 ml min-1. However, the breakthrough point could not be identified due to�the column clogging (12 h).�Overall, modified adsorbents produced had the ability to remove FOG, which indicated that rain tree residue could be utilized as an alternative adsorbent�precursor for FOG treatment.
