“…Finally, the BC has high reusability, and the loss of adsorption capacity for phenol and DNP is less than 20% after five cycles. Lawal et al (2021) used BC made from oil palm leaves by steam pyrolysis to remove phenol; the adsorption capacity reached 62.89 mg/g for phenol and was well fitted with the Freundlich model (R 2 = 0.9863), and the mechanism of the phenol removal was illustrated in Fig. 3a.…”

“…And BC still effectively removed about 80% Fig. 3 a The mechanism of adsorption of phenol on the surface of BC (Lawal et al 2021), b the mechanism of photocatalytic degradation for phenol induce by CCNC/ZnO (Zhang et al 2020b) of phenolic pollutants in field applications. The maximum adsorption capacity of BC for phenol and DNP were 106.2 mg/g and 148.1 mg/g, respectively, which were ascribe to the high surface area, rich in pore structure, and the large oxygen surface functional groups on BC.…”

Biochar (BC) has exhibited a great potential to remove water contaminants due to its wide availability of raw materials, high surface area, developed pore structure, and low cost. However, the application of BC for water remediation has many limitations. Driven by the intense desire of overcoming unfavorable factors, a growing number of researchers have carried out to produce BC-based composite materials, which not only improved the physicochemical properties of BC, but also obtained a new composite material which combined the advantages of BC and other materials. This article reviewed previous researches on BC and BC-based composite materials, and discussed in terms of the preparation methods, the physicochemical properties, the performance of contaminant removal, and underlying adsorption mechanisms. Then the recent research progress in the removal of inorganic and organic contaminants by BC and BC-based materials was also systematically reviewed. Although BC-based composite materials have shown high performance in inorganic or organic pollutants removal, the potential risks (such as stability and biological toxicity) still need to be noticed and further study. At the end of this review, future prospects for the synthesis and application of BC and BC-based materials were proposed. This review will help the new researchers systematically understand the research progress of BC and BC-based composite materials in environmental remediation.

“…Basic functional groups are usually obtained by reducing oxygen functional groups or introducing nitrogen functional groups on the carbon surface. Furthermore, to ensure that the impurities in the biodiesel have accessibility towards the adsorption site, pore sizes of the adsorbent should be wide enough [37]. Alnaief et al [38] compared the effect of different particle sizes (≤90 µm and ≤150 µm) of activated carbon on biodiesel purification.…”

Biodiesel or known as fatty acid methyl ester (FAME), is a diesel fuel substitute derived from the transesterification reaction of triglycerides with alcohol in the presence of suitable catalyst. The demand for biodiesel is increasing due to environmental and health awareness, as well as diminishing energy security. However, the presence of impurities in biodiesel will affect engine performance by corroding fuel tubes and damaging the injectors. Common methods for the purification of biodiesel include water washing, dry washing and membrane separation. This mini review compares the technological advancement for efficient enhancement of biodiesel and glycerol refining between wet washing, dry washing (activated compound, biomass-based adsorbents and silica-based adsorbents), ion exchange and membrane separation technology. The percentage of glycerol residues, soap, alcohol and catalyst from crude biodiesel was compared to reflect the resulting biodiesel purity variation. The advantages and disadvantages of each method were also discussed.

“…Recently, consideration has focused on sustainable options such as biochar (Lee et al 2019;Lawal et al 2020). Biochar has been used in treatment of wastewater that contains organic compounds, including phenol compounds (Lawal et al 2021). This adsorbent was used due to its unique properties (low cost, high efficiency, operating over a wide range of temperature, and low energy consumption) (Sabzehmeidani et al 2021).…”

Removal of phenol from wastewater using local biochar (BC) was investigated, while using activated carbon (AC) as a reference material. The main parameters affecting the sorption process were initial concentration, contact time, pH, and temperature. Statistical analysis of the results showed that the maximum removal percent when using AC and BC were 95% and 55%, respectively. Experimental data showed that the removal of phenol has fast kinetics and reached equilibrium within 5 minutes. The Langmuir and Freundlich isotherm models were applied to fit the adsorption experimental data. Pseudo-first order and pseudo-second order kinetic models were employed.
