“…In addition to the increased polar group number (-NH-C=O) in the monomer backbone for (D1-D3) [28]. The other reason is the decrease in the length of the alkyl chain from the number of carbon atoms (10) in monomers D3 to the number of carbon atoms (8) in monomers D2 to the number of carbon atoms (5) in monomers D1 [29]. Furthermore, molecules with aliphatic (linear) chains have better hydrophobicity than branched or aromatic molecules, owing to the s teric effect of the neighboring branches and aromatic rings that reduce the hydrophobic interactions with the water molecule.…”

The aquatic environment may be seriously harmed when cargo gases, diesel, and their compounds leak or are accidentally spilled onto the water's surface. Oil exploration also leads to water contamination. The remaining oil coats the water's surface, resulting in the formation of a thin emulsion of water and oil. Three novel compounds with long chains of linear alkyl groups were grafted to flexible polyurethane (R-FPU) to clean up oil spills. The sorption testing was thoroughly examined and contrasted with the aid of crude oil, diesel fuel, and water-oil systems. It was found that as compared to ungrafted FPU, the chemical sorption of crude oil and diesel fuel was boosted by modified FPU cubes, while water sorption was reduced by roughly 57%. The sorption competence of the modified FPU was highly correlated with the length of the alkyl chain, with the longer alkyl chain significantly increasing sorption capacity. The results demonstrate that oil may be successfully cleaned using modified FPU cubes.

“…Dye concentrations ranging from 1 to 100 mg/L were employed to analyze the Langmuir and Freundlich isotherm models, as shown in Figure 9, at an initial pH of 6.0 and adsorbent dosage of 0.1 g. The monolayer adsorption capacity exhibited the following trend: CBC600 > CBC500 > CBC400 > CBM. CBC600 (17.1 mg/g), and CBC500 (13.4 mg/g) exhibited the maximum adsorbent capacity for the removal of dye molecules [47]. Isotherm study data were fitted in the Langmuir isotherm model equation:…”

Castor Leaves-Based Biochar for Adsorption of Safranin from Textile Wastewater

et al. 2021

The prospect of synthesizing biochar from agricultural wastes or by-products to utilize them as a promising adsorbent material is increasingly gaining attention. This research work focuses on synthesizing biochar from castor biomass (CBM) and evaluating its potential as an adsorbent material. Castor biomass-based biochar (CBCs) prepared by the slow pyrolysis process at different temperatures (CBC400 °C, CBC500 °C, and CBC600 °C for 1 h) was investigated for the adsorption of textile dye effluents (safranin). The pyrolysis temperature played a key role in enhancing the morphology, and the crystallinity of the biochar which are beneficial for the uptake of safranin. The CBC600 adsorbent showed a higher safranin dye removal (99.60%) and adsorption capacity (4.98 mg/g) than CBC500 (90.50% and 4.52 mg/g), CBC400 (83.90% and 4.20 mg/g), and castor biomass (CBM) (64.40% and 3.22 mg/g). Adsorption data fitted better to the Langmuir isotherm model than to the Freundlich isotherm model. The kinetics of the adsorption process was described well using the pseudo-second-order kinetic model. The study on the effect of the contact time for the adsorption process indicated that for CBC600, 80% dye removal occurred in the first 15 min of the contact time. After three regeneration cycles, CBC600 exhibited the highest dye removal efficiency (64.10%), highlighting the enhanced reusability of CBCs. The crystalline patterns, functional binding sites, and surface areas of the prepared CBCs (CBC400, CBC500, CBC600) were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and Brunauer–Emmett–Teller surface area measurements, respectively.

“…The Deepwater Horizon oil spill in the Gulf of Mexico in 2010 not only caused severe pollution in the marine ecosystem, but also caused incalculable economic losses. 1 In recent years, all kinds of methods 2 have been widely used for oil spill recovery, including chemical dispersion, 3 biodegradation, 4 use of adsorbents 5 and skimmers, 6 burning, 7 membrane separation, 8 use of solidifiers 9 and so on. These techniques can realize the recovery of oil spills or the weakening of the negative influence caused by oil spill accidents.…”
