“…The N1s spectrum of TBC in Figure 4C shows that nitrogen is mainly in the form of pyridine nitrogen (398.52 eV) and pyrrole nitrogen (400.72 eV) [39]. After activation by K 2 CO 3 , C-C/C=C and C=O functional groups increased significantly (Figure 4D), and the presence of a peak of O-C=O (534.57 eV) was observed in the O1s spectrum of K-TBC (Figure 4E) [40]. In addition, the nitrogen functional groups in Figure 4F also changed significantly, with the proportion of pyrrole nitrogen increasing significantly and the presence of graphite nitrogen (403.32 eV) [41].…”

Norfloxacin (NOR) is a common antibiotic used in humans and animals, and its high levels can cause intolerance or poisoning. Therefore, NOR levels in animal-derived foods must be monitored due to potential side effects and illegal use phenomena. This research centered on the development of an environmentally friendly electrochemical sensor for NOR detection. Potassium carbonate activated tea branch biochar (K-TBC) as an efficient use of waste was coated on the surface of glassy carbon electrode (GCE), and a molecular-imprinted polymer (MIP) layer was subsequently electropolymerized onto the modified electrode. NOR was used as template molecule and o-phenylenediamine (o-PD) and o-aminophenol (o-AP) were used as bifunctional monomers. The electrochemical sensor was built and its electrochemical behavior on NOR was investigated. The sensor demonstrated an excellent linear current response to NOR concentrations in the ranges of 0.1–0.5 nM and 0.5–100 nM under ideal experimental circumstances, with a detection limit of 0.028 nM (S/N = 3). With recoveries ranging from 85.90% to 101.71%, the designed sensor was effectively used to detect NOR in actual samples of milk, honey, and pork. Besides, the fabricated sensor had low price, short detection time, good selectivity and stability, which can provide a theoretical and practical basis for the actual monitoring of NOR residues.

“…Anthonysamy et al. (2021) concluded that the decomposition reaction of KOH and K 2 CO 3 occurred above the activation temperature of 600°C. When the temperature exceeded 650°C, the reduction reaction between K 2 CO 3 and K 2 O occurred and mainly carbon was produced (Chen et al., 2020).…”

Biochar, a black carbon material produced by high‐temperature, low‐oxygen pyrolysis of organic solids, can improve soil properties and realize carbon neutrality. However, how to effectively produce and apply biochar in the face of the complex soil environment and intractable widespread land degradation is still uncertain. This review is based on 1073 sets of data in 316 publications to address this issue. Firstly, the impact of different process parameters, namely feedstocks, pyrolysis temperature and activation on physicochemical properties of biochar are systematically summarized. Secondly, the effect of biochar on different soil degradation problems are reviewed from the perspective of the interaction between the physicochemical properties of biochar and soil characteristics. The “matching” of biochar properties, level of degradation and environmental factors can be used to design the desired biochar. Finally, future research should focus on biochar aging and costs and benefits of using biochar. The concept of “artificial intelligence designed biochar” is discussed to improve the degree of automation in biochar production and the predictability and suitability of its application for specific cases.
