Summary: A new N-doped biochar (NSB) was prepared by one-pot pyrolysis using sugarcane bagasse, melamine, and NaHCO3 as feedstock, nitrogen source, and pore-forming agent, respectively. The physicochemical properties of NSB were characterized by SEM, EDS, XRD, FTIR, XPS, and BET analyses, confirming its excellent pore structure, high specific surface area, and nitrogenous functional groups. The optimized conditions for CIP adsorption by NSB were determined, and a CIP adsorption capacity of 212 mg/g was achieved under these conditions. The adsorption mechanism involved pore filling, 7C-7C conjugation, and hydrogen bonding. This study demonstrates the reliable technology of using low-cost NSB for the treatment of CIP wastewater.

Summary: This review investigates the impact of N-doped and Fe/N co-doped biochar (BC) on the removal of refractory organic pollutants (ROPs) through adsorption, activation oxidation, and catalytic reduction. The study found that N-doped and Fe/N co-doped BCs can effectively remove ROPs by modifying the physicochemical properties, surface functional groups, and persistent free radicals of BC to aid in the degradation of ROPs. Additionally, the review discusses the applications and mechanisms of N-doped and Fe/N co-doped BCs in environmental remediation.

Summary: KOH-activated N-doped hydrochar (KHCN) was synthesized and investigated for atrazine (AT) removal. The results showed that KHCN had a larger specific surface area and unique microsphere structures, leading to superior adsorption capacity compared to the primitive hydrochar. Furthermore, KHCN exhibited pH-dependent AT removal and excellent uptake capacity at a relatively neutral environment. The mechanisms for AT removal by KHCN were identified as electrostatic attraction, pore filling, hydrogen bonding, etc.

Summary: An autogenous N-doped biochar derived from Chlorella was prepared using NaOH as an activator at 800 degrees C. The specific surface area of the biochar was found to be 491.16 m2 g-1 and its adsorption of tetracycline followed the Freundlich model and pseudo-second-order kinetic model. The maximum adsorption capacity of tetracycline was 310.696 mg g-1 at pH 9 and 50 degrees C, primarily due to physical adsorption. The cyclic adsorption-desorption behavior of the biochar using ethanol as an eluent was also evaluated, demonstrating its suitability for long-term applications.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
