“…Therefore, the adsorption rate was controlled by external mass transfer and intraparticle diffusion. Furthermore, the intercept of the second part is not zero, confirming that the adsorption reaction is also controlled by other steps (Chabi et al, 2020).…”

“…By increasing the TC concentration from 5 mg/L to 50 mg/L, the removal efficiency of TC by PBC decreased from 99.34 to 67.01%, and the removal efficiency of TC by TPBC decreased from 99.79 to 83.13%. The higher removal efficiency at lower initial concentrations is due to the sufficient number of adsorption sites for TC adsorption (Chabi et al, 2020). However, the ratio of adsorption sites to TC molecules decreased with increasing TC concentration, decreasing the sites available for TC adsorption.…”

“…Figure 2 shows that the removal efficiency of TC by TPBC was significantly higher than that of PBC with different biochar dosages. When the biochar dosage was increased from 500 to 1500 mg/L, the removal efficiency of TC by PBC increased from 39.52 to 67.01%, and the removal efficiency of TC by TPBC increased from 49.93 to 83.13%, perhaps due to the growth of adsorption sites (Chabi et al, 2020). Moreover, the growth rate of the TC removal efficiency increased when the biochar dosage was increased from 500 to 1,250 mg/L, whereas the growth rate of the TC removal efficiency decreased when the biochar dosage was 1,500 mg/L.…”

BACKGROUND: Anaerobically reduced textile dyeing wastewater containing aromatic amines can cause serious environmental problems as a consequence of their toxicity. RESULTS:The performance of a novel design, laboratory-scale mica@reduced graphene oxide (rGO) reactor fixed on three rotating disks was evaluated for the removal of anaerobically reduced textile dyeing wastewater containing aromatic amines. Fourier-transform infrared and UV-visible spectroscopy analyses of wastewater after anaerobic treatment revealed that it contained high aromatic compound concentrations. Scanning electron microscope images confirmed that the rGO nanosheets were deposited on the mica surface by the spin-coating method aromatic amines adsorbent. The effects of wastewater initial chemical oxygen demand (COD) concentration (100, 500 and 1500 mg L -1 ), pH (5, 7 and 9) and processing temperature (293, 303 and 313 K) on the aromatic compounds and COD removal using the designed reactor were investigated. The results indicated that aromatic molecule adsorption occurred faster with higher wastewater COD concentration. Also, increase in pH improved the mica@rGO adsorption. Likewise, the increase in temperature caused swelling in the stacked graphene layers, resulting in new surfaces for adsorption, leading to an increase in reactor efficiency. The experimental results indicated that the adsorption process fitted well with the Langmuir isotherm model and pseudo-second-order reaction kinetics. The thermodynamic study revealed that the adsorption was spontaneous. CONCLUSION:The improvement in the removal of aromatic molecules by Mica@rGO indicates that the novel designed reactor has a great potential for the treatment of textile wastewater.

In this study, two types of magnetic biochars (Magnetic Bark Biochar with protocol 1 (MBB1) and Magnetic Bark Biochar with protocol 2 (MBB2)) were synthesized using pristine poplar bark biochar (PBB) via co‐precipitation. The two prepared magnetic biochars were tested to investigate the aqueous methylene blue (MB) removal performances. MB dye was used as a common pollutant for biochar quality evaluation and the obtained performance in this work was compared with literature. Different analysis techniques such as Scanning Electron Microscope (SEM), Energy Dispersive X‐ray Spectroscopy (EDS), Brunauer‐Emmett‐Teller (BET), porosimetry, Raman spectrometry and Fourier Transform Infrared spectroscopy (FTIR) were used to characterize the obtained materials. Biochars have a microporous structure with an average pore diameter of less than 0.26 nm. Magnetization of bark biochar leads to a loss in specific surface area (from 263.45 m2/g for PBB to 39.22 and 73.02 m2/g for MBB1 and MBB2, respectively) and an increase in total porosity by 85.11 and 12.72 %, respectively. MB adsorption process on MBB1 and MBB2 was best described by the pseudo‐first‐order kinetic model (R2=0.98) and by pseudo‐second‐order kinetic model for PBB (R2=0.9). The Langmuir monolayer adsorption and Marczewski‐jaroniec (M‐J) models presented the best fit for both PBB and MBB2 showing favourable adsorption process. Based on maximum adsorption capacity (qm: 32.98 mg/g) and the highest R2 value (0.96), MBB1 adsorption isotherm was well described by Langmuir model. Isotherm study revealed that MBB2 has the highest adsorption capacity of 49.02 mg/g followed by PBB with 37.85 mg/g. MB‐biochar interactions are dominated by chemisorption regarding the PBB and by physisorption concerning the magnetic biochars.
