| 中文摘要: |
| 本研究以硫酸盐木质素（KP）为原料，经盐酸分级预处理后，利用碱式碳酸镁（MBC）与三聚氰胺进行协同活化-掺氮改性，制得木质素基多孔炭，并初步考察了其对水相中烟碱类杀虫剂吡虫啉（IMI）的吸附表现。结果表明，pH值=9的环境下盐酸分级预处理可有效优化木质素基多孔炭的孔隙结构与表面化学活性；制得木质素基多孔炭（KP9@MBC@N）的比表面积、总孔体积和平均孔径分别为1 693.8 m2/g、0.56 cm3/g和2.52 nm。在IMI溶液初始质量浓度200 mg/L、KP9@MBC@N投加量10 mg、吸附温度35 ℃、吸附时间120 min的条件下，KP9@MBC@N对IMI的最大吸附量可达294.4 mg/g；推测其对IMI的吸附作用包括孔隙填充及一定的弱化学作用。 |
| Abstract: |
| In this study， kraft lignin （KP） was used as raw material and subjected to hierarchical pretreatment with hydrochloric acid， followed by synergistic activation and nitrogen doping modification using magnesium carbonate （MBC） and melamine to produce lignin-based porous carbon. The adsorption performance of lignin-based porous carbon towards the neonicotinoid insecticide imidacloprid (IMI) in an aqueous solution was preliminarily investigated. The results indicated that staged hydrochloric acid pretreatment at pH value of 9 effectively optimized the pore structure and surface chemical activity of the lignin-based porous carbon (KP9@MBC@N). The specific surface area， total pore volume， and average pore diameter of the resulting KP9@MBC@N were 1 693.8 m2/g， 0.56 cm3/g， and 2.52 nm， respectively. Under the conditions of IMI solution initial concentration of 200 mg/L， adsorbent dosage of 10 mg， adsorption temperature of 35 ℃ and adsorption time of 120 min， the maximum adsorption capacity of KP9@MBC@N towards IMI could reach 294.4 mg/g. It was hypothesized that the adsorption mechanism towards IMI mainly involved pore filling and some mild chemical reactions. |
