“…Moreover, the pseudo-first order models (R 2 = 0.987-0.994) fitted the data lightly greater than pseudo-second order models (R 2 = 0.967-0.973) for the adsorption of TCC, which implied that the pore diffusion process was the rate-limiting step (Supplementary Table S3; Alberti et al, 2012). It was also confirmed that all adsorption rate constants (k 1 ) were much better than k 2 (Supplementary Table S3; Qi et al, 2022). Combined with the results of SEM and BET, BC 700 increased the surface area, pore volume, and pore diameter of biochar compared with BC 300 and BC 500 , which facilitated the diffusion of TCC in the pores of biochar, thus increasing the TCC adsorption efficiency of biochar (Supplementary Figure S1).…”

Triclocarban (TCC), an emerging organic contaminant (EOC), has become a severe threat to soil microbial communities and ecological security. Here, the TCC-degrading strain Rhodococcus rhodochrous BX2 and DCA-degrading strain Pseudomonas sp. LY-1 (together referred to as TC1) were immobilized on biochar to remove TCC and its intermediates in TCC-contaminated soil. High-throughput sequencing was used to investigate the microbial community structure in TCC-contaminated soil. Analysis of co-occurrence networks was used to explore the mutual relationships among soil microbiome members. The results showed that the immobilized TC1 significantly increased the removal efficiency of TCC from 84.7 to 92.7% compared to CK (no TC1 cells on biochar) in 10 mg/L TCC liquid medium. The utilization of immobilized TC1 also significantly accelerated the removal of TCC from contaminated soil. Microbial community analysis revealed the crucial microorganisms and their functional enzymes participating in TCC degradation in soil. Moreover, the internal labor division patterns and connections of TCC-degrading microbes, with a focus on strains BX2 and LY-1, were unraveled by co-occurrence networks analysis. This work provides a promising strategy to facilitate the bioremediation of TCC in soil, which has potential application value for sustainable biobased economies.

“…However, the pore collapse decreased the specific surface area when the pyrolysis temperature exceeded 800 °C and weakened the adsorption capacity of the adsorbent. [35] In addition, the phosphate adsorption performance of the tobacco stem-based biochars prepared at 800 °C with different raw material particle sizes was also determined. Biochars prepared with a raw material particle size < 2 mm showed no significant difference in phosphate adsorption capacity and removal rate, but these significantly decreased when the raw material particle size was > 2 mm.…”

Phosphorus is an important element for plant growth. The efficient use and recovery of phosphorus is crucial due to limited phosphate resource reserves. This study explored the potential application of an in situ Ca and Mg co‐doped biochar derived from tobacco stem to reclaim and reuse phosphate from aqueous solutions. We performed various batch adsorption experiments and industrial analysis based on different parameters. The findings indicate that biochar prepared using the raw material particle size range of 0.85–2 mm and pyrolyzed at 800 °C presented good pore structure and specific surface area. Ca and Mg elements in biochar exhibited great influence on its phosphate adsorption property. The maximum phosphate adsorption capacity of the tobacco stem‐based biochar was 54.66 mg/g, and the experimental data agreed with the Langmuir equation, suggesting monolayer adsorption. The adsorption process conformed to the pseudo‐second‐order kinetic equation, indicating that chemisorption was the dominant adsorption process and that the adsorption was controlled by intra‐particle diffusion. Furthermore, phosphate adsorbed on tobacco stem‐based in situ Ca and Mg co‐doped biochar was released under acidic, alkaline, and neutral conditions. Therefore, in situ Ca and Mg co‐doped biochar prepared from tobacco stems is a potential environmentally friendly and low‐cost adsorbent for phosphorus recovery.

“…25 Ball milling in atmospheres or combination with other chemicals may influence the surface functional groups of adsorbent, thus altering its ability to adsorb different pollutants. 26 For instance, ball-milled biochar was modified with hydrogen peroxide (H 2 O 2 ) and ammonia hydroxide (NH 3 ·H 2 O), effectively changing the morphological characteristics and improving its adsorption capacity for aromatic volatile organic chemicals. 27 However, using H 2 O 2 as a modifier in combination with ball milling for physical-chemical modification is still at a preliminary stage, especially in the field of pharmaceuticals removal.…”
