“…The surfactant modification favoured the increase of the polymer adsorption amount on both examined adsorbents. The poly(acrylic acid) removal from the aqueous solution is strongly related to its pH value, however, at all examined pH values (3,6,9), the anionic polymer is better adsorbed on the surface of the CTAB-modified activated biochar. In such a case the maximum PAA adsorbed amount was 68 mg/g.…”

“…The surfactant modification had a small impact on the PAA adsorbed amount. Moreover, the changes in the solution pH values (3,6,9) influenced the poly(acrylic acid) adsorbed amount more significantly compared with any adsorbents modifications with the surface active agent. The obtained maximum adsorbed amount of PAA on the Triton X-100-modified activated biochar was 55 mg/g.…”

“…The most important applications of biochar concern soil amendment and agriculture [1][2][3] , but recently much has been achieved in the design of biochar-supported nanocatalysts for water treatment consisting in total mineralization of organic pollutants such as dyes and drugs 4,5 . Other applications concern the use of biochar as fillers in composite materials [6][7][8] , electrode materials 9,10 and for the developments of novel engineered biochar for the treatment of neglected tropical diseases (NTDs) 11,12 , to name but these applications.…”

In the recent years, biochar has emerged as a remarkable biosourced material for addressing global environmental, agricultural, biomedical, and energy challenges. However, the performances of biochar rest in part on finely tuning its surface chemical properties, intended to obtain specific functionalities. In this review, we tackle surface treatment of biochar with silane and other coupling agents such as diazonium salts, titatantes, ionic/non-ionic surfactants, as well as nitrogen-containing (macro)molecules. We summarize the recent progress achieved mostly in the last five years, and correlate the nature and extent of functionalization to eye catchy end applications of the surface engineered biochar.

“…Attempts have been made to reduce the residues of dyes by physical or chemical means such as ion exchange, coagulation, adsorption, ultrasonic catalysis, electrochemical methods, and microbial‐assisted degradation, for ecological protection. Among these approaches (Gupta et al, 2015; Harussani & Sapuan, 2021), adsorption techniques are widely utilized because of their ability to remove dyes by using materials, such as ores, biomass charcoal, and chitosan, which are cost effective and do not produce toxic substances (Huang, Jiang, & Yu, 2020; Shi et al, 2020).…”

Azo dye residues pollute water, which are difficult to decompose, and posing a major threat to the ecological environment. The residues of Chinese medicine still have many possibilities for use after its medicinal value has been brought into play. In this study, secondary residue biochar activation (Na2CO3‐modified, SBA) and secondary residue biochar (unmodified, SBC) were prepared from the secondary residue of snow lotus at 200–600°C. Surface features were obtained by Brunauer–Emmett–Teller N2 method and combined with scanning electron microscopy, and their structures were analyzed by x‐ray diffraction spectroscopy, Fourier infrared and near‐infrared spectroscopy. The effects of five factors, including initial concentration, contact time and adsorption temperature and so forth, on the adsorption of methyl red (MR) and methyl orange (MO) solutions were investigated. Results showed that the biochar yield, specific surface area, and pore size increased after modification. modification promoted the formation of the internal structure aromatization and oxygen‐containing functional groups. Adsorption experiments showed that the surroundings pH = 8, the dyes adsorption concentration of 8 mg/L, adsorption temperature of 20–40°C and time of about 1 h were more stable. Under the condition, the removal of MO by SBA could reach approximately 60%–80% (480–640 mg/g), while the removal of MR could reach more than 90% (>720 mg/g).The charcoal prepared and modified under high temperature conditions was more effective for MO adsorption, while MR relied on low temperature effectively. This study provides a new choice of adsorbent for MR and MO and finds a new direction for the utilization of snow lotus residues.

“…Although graphene, carbon nanotubes, fullerene are advanced carbon based materials 9 , yet they are excessively expensive which limits the expansion of their utilization. Instead, one can take advantage of biochar(s) generated from the pyrolysis of agrowastes and other biomass resources 10,11 . Biochar can be regarded as a promising candidate possessing several attractive features which can further be tuned via acid or base surface chemical treatment 12,13 , loading of alkali metal oxalate loading 14 , amine functionalization using diethanolamine 15 , or silanization 16 .…”

There is an ever growing interest worldwide in the development of biochar from a large variety of agrowastes. This work contributes to the domain by tackling an agrowaste represented in pomegranate peels powder. The latter was activated by acid treatment and then pyrolyzed to generate low cost biochar. To enrich the surface of the resulting biochar, it was arylated with various in-situ generated diazonium salts of 4-aminobenzoic acid (H2N-C6H4-COOH), sulfanilic acid (H2N-C6H4-SO3H) and Azure A dye. The effect of diazonium nature and concentration on the arylation process was monitored essentially using thermal gravimetric analysis (TGA), and Raman spectroscopy. These techniques showed gradual changes in the arylation of biochar at low concentrations of 10-5, 10-4 and 10-3 M of 4-aminobenzoic acid. Interestingly, Azure A diazonium salt induces lower extent of surface modification, likely due to steric hindrance. One key feature of this work is the correlation between D/G Raman peak intensity ratio and the mass loading of the aryl groups. To the very best of our knowledge this is the first report ever on diazonium modification of agrowaste-derived biochar and opens new avenues for such carbon allotrope, i.e. surface arylation and applications.
