摘要：Herein, a straightforward protocol was developed for the one -pot synthesis of N -doped lignosulfonate-derived carbons (NLDCs) with a tunable porous structure using natural amino acids-templated self -assembly strategy. Specifically, histidine was employed as a template reagent, leading to the preparation of 10-NLDC-21 with remarkable characteristics, including the large specific surface area ( S BET = 1844.5 m 2 /g), pore volume ( V mes = 1.22 cm 3 /g) and efficient adsorption for atrazine (ATZ) removal. The adsorption behavior of ATZ by NLDCs followed the Langmuir and pseudo -second -order models, suggesting a monolayer chemisorption nature of ATZ adsorption with the maximum adsorption capacity reached up to 265.77 mg/g. Furthermore, NLDCs exhibited excellent environmental adaptability and recycling performance. The robust affinity could be attributed to multiinteractions including pore filling, electrostatic attraction, hydrogen bonding and 7C -7C stacking between the adsorbents and ATZ molecules. This approach offers a practical method for exploring innovative bio-carbon materials for sewage treatment.
