“…As for CSB and CSMB, they contain O-H, N-H, C-H, C=O, C-N, C=C and C-Br function groups at peak bands of 3500-3800 cm −1 , 2500-2900 cm −1 , 1300-2400 cm −1 and 500-800 cm −1 . In addition, the modified corn stalk biochar (CSMB) has more function groups at bands of 3915 cm −1 for the N-H stretching of amide group, 3500 for the O-H strong broad stretching of alcohol group, 1266 cm −1 for the strong alkyl ether C=O groups, 1116 cm −1 for the aromatic C-H group, 755 cm −1 for the alkene C=C stretch bending group and 360 cm −1 for the phenol benzene groups [41][42][43][44][45]. and 500-800 cm −1 .…”

Soil salinity and sodicity is a potential soil risk and a major reason for reduced soil productivity in many areas of the world. This study was conducted to investigate the effect of different biochar raw materials and the effects of acid-modified biochar on alleviating abiotic stresses from saline-sodic soil and its effect on biochemical properties of maize and wheat productivity. A field experiment was conducted as a randomized complete block design during the seasons of 2019/2020, with five treatments and three replicates: untreated soil (CK), rice straw biochar (RSB), cotton stalk biochar (CSB), rice straw-modified biochar (RSMB), and cotton stalk-modified biochar (CSMB). FTIR and X-ray diffraction patterns indicated that acid modification of biochar has potential effects for improving its properties via porous functions, surface functional groups and mineral compositions. The CSMB treatment enhanced the soil’s physical and chemical properties and porosity via EC, ESP, CEC, SOC and BD by 28.79%, 20.95%, 11.49%, 9.09%, 11.51% and 12.68% in the upper 0–20 cm, respectively, compared to the initial properties after the second season. Soil-available N, P and K increased with modified biochar treatments compared to original biochar types. Data showed increases in grain/straw yield with CSMB amendments by 34.15% and 29.82% for maize and 25.11% and 15.03% for wheat plants, respectively, compared to the control. Total N, P and K contents in both maize and wheat plants increased significantly with biochar application. CSMB recorded the highest accumulations of proline contents and SOD, POD and CAT antioxidant enzyme activity. These results suggest that the acid-modified biochar can be considered an eco-friendly, cheaper and effective choice in alleviating abiotic stresses from saline-sodic soil and positively effects maize and wheat productivity.

“…The activators have a significant impact on the porosity and functionality of activated carbons. In previously reported literature, various adsorbent materials, including activated carbon functionalized with graphene oxide, 39 Fe 0 -loaded activated carbon, 40 manganese oxide OMS-2 loaded on activated carbon, 41 magnetic-activated, 42 and jack fruit peel 43 were deployed for the remediation of a wide range of pharmaceutical compounds from the aquatic system.…”

“…Such a behavior could be ascribed to the dehydration that happens during the thermal treatment process (Figure 1) [69]. Similar attributes could be observed upon chemical modification of biomasses or biochars [72]. FTIR spectroscopy identifies not only the structural alterations of the lignocellulosic biomass but also the presence of carbohydrate, protein, and lipid in the non-lignocellulosic biomass [77].…”

“…On the other hand, biopolymer compositional analysis shows that peanut shells contain 18.8% of cellulose and 81.2% of lignocellulose [68]. Table 1 shows examples of the applications of peel-based adsorbents (raw, thermally, and chemically treated) for the removal of various pollutants (heavy metals, dyes, and drugs) [69][70][71][72][73][74][75][76]. Table 1 shows the most characteristic FTIR peaks of the studied peels; the suggested removal mechanism of the target pollutant, whether physi-or chemisorption; as well as the reported maximum sorption capacity (q max , mg/g).…”

Infrared Spectroscopy - Perspectives and Applications

View full text Add to dashboard Cite

Global economies are confronting major energy challenges. Mitigating the energy depletion crisis and finding alternative and unconventional energy sources have been subjects for many investigations. Plant-sourced biomasses have started to attract global attention as a renewable energy source. Maximizing the performance of the biomass feedstock in different applications requires the availability of reliable and cost-effective techniques for characterization of the biomass. Comprehending the structure of lignocellulosic biomass is a very important way to assess the feasibility of bond formation and functionalization, structural architecture, and hence sculpting of the corresponding structure−property liaison. Over the past decades, non-invasive techniques have brought many pros that make them a valuable tool in depicting the structure of lignocellulosic materials. The current chapter will be focused on the applications of Fourier transform infrared (FTIR) spectroscopy especially in the mid-infrared region in the compositional and structural analysis of lignocellulosic biomasses. The chapter will provide a display of examples from the literature for the application of FTIR spectroscopy in finding the composition of various biomasses obtained from different parts of plants and applied for wastewater treatment. A comparison between biomasses and physically/chemically treated products will be discussed.
