Effective Adsorption of Diesel Oil by Crab-Shell-Derived Biochar Nanomaterials

Abstract: This study, for the first time, rendered crab shell activated biochar modified by potassium hydroxide (KOH) impregnation (CSAB), revealing a new potential application in the removal of diesel oil from oily wastewater. The structural characteristics of crab shell biochar (CSB) and CSAB were investigated by SEM, and the crystal structure and optical properties of as-prepared samples were analyzed using XRD and FTIR. Results showed that CSAB had stratified surface structure morphology, abundant functional groups,… Show more

“…Figure 1 shows the FTIR results for the identification of the present functional groups in the PMT and CCLHR species. In the range of 3000–3720 cm −1 , a broad and low intensity band was observed, peaks at 3330 cm −1 (Figure 1a) and 3320 cm −1 (Figure 1b), characterizing the presence of O–H (alcohols and phenols) [44]. Peaks were also observed at 1630 cm −1 (Figure 1a) and 1613 cm −1 (Figure 1b), which indicated the C = O stretching in organic groups of carboxyl and bending vibration of the functional group –OH [45].…”

“…Ngarmkam and coworkers [46] carried out research on the removal and recovery of residual oil onto palm shell-based carbon; the equilibrium adsorption capacity of samples reached 30–90 mg/g. Cai et al [47] explored the adsorption properties of diesel oil on modified crab shell-activated biochar carbon; the adsorption capacity was 93.9 mg/g. Although the oil sorption capacity of MAFC obtained in this experiment was 45.5 mg/g, which is relatively low compared with other adsorbents, waste fish bone materials have potential to be applied for the removal of oil, at no cost.…”

“…the semi crystalline structure of chitin). Finally, the diffraction peak of the (104) plane is the most intense peak for calcite in CCM, indicating that CaCO 3 in the crab carapace is in crystallised calcite form along the biopolymer chains (Cai et al 2019).…”

“…The normalised XRPD patterns show the presence of both an amorphous phase, which is associated with the organic component of the material, e.g. chitin/chitosan polymer and a crystalline phase, which was identified as calcite (Swanson et al 1953;Zhou et al 2016;Cai et al 2019). The broad diffraction peaks observed at around 9.6°and 19°in the raw material (representing the amorphous chitin structure) are found to sharpen after activation, suggesting the material has crystallised during the activation process (Arulvel et al 2017).…”
