本试验以新疆南疆废弃灰枣叶为原料制备原始生物质炭(YBC),并通过Na_2SO4改性制备灰枣叶改性生物质炭(M-YBC),以亚甲基蓝溶液(MB)模拟印染污水，将制备的改性生物质炭用于印染污水处理。采用Brunauer-Emmett-Teller氮气吸附法(BET)、扫描电子显微镜-能谱仪(SEM-EDS)、热重分析仪(TGA)、X射线光电子能谱仪(XPS)、拉曼散射光谱仪(Raman)和X射线衍射仪(XRD)等方法对YBC和M-YBC进行表征。结果表明，经Na_2SO4处理后，随着碳化程度增加，BET比表面积(SBET)和孔数量都有所增加，M-YBC的SBET达到了419.03 m2/g,其对MB的吸附性能也明显提高。M-YBC对MB的饱和吸附容量可达298.77 mg/g,较YBC提高了637.70%,与购买的商业活性炭(AC)对比发现，M-YBC的饱和吸附容量约为AC的5倍，差异极其显著(P<0.000 1)。此外，对MB吸附过程进行动力学和等温吸附模型分析发现，YBC和M-YBC对MB的吸附机理复杂，主要以表面络合、静电吸引和氢键作用导致的化学吸附为主。本研究可为新疆枣产业废弃资源的综合利用和生物质炭在防治印染污水中的应用提供一定的参考价值。
Abstract：Original biochar(YBC) was prepared from discarded ziziphus jujuba cv.huizao leaves in Southern Xinjiang, and modified with Na_2SO4 to yield modified biochar of ziziphus jujuba cv.huizao leaves(M-YBC). The utility of both biochars was explored in the treatment of simulated printing and dyeing wastewater simulated by methylene blue(MB). Comprehensive characterization of YBC and M-YBC was conducted employing Brunauer-Emmett-Teller nitrogen adsorption method(BET), scanning electron microscope-energy dispersive spectrometer(SEM-EDS), thermogravimetric analysis(TGA), X-ray photoelectron spectroscopy(XPS), raman spectroscopy(Raman), and X-ray diffraction(XRD) techniques. The results demonstrated that after treatment with Na_2SO4, the BET specific surface area(SBET) and porosity of the biochar increased with the carbonization degree. The SBET of M-YBC reached 419.03 m2/g, which led to a significant enhancement in its adsorption capacity for MB. The saturated adsorption capacity of M-YBC for MB reached 298.77 mg/g, which was 637.70% higher than YBC, and about 5 times that of commercial activated carbon(AC), and the difference is extremely significant(P<0.000 1). In addition, analyses of kinetic and isothermal adsorption models revealed a complex adsorption mechanism involving surface complexation, electrostatic attraction, and hydrogen bonding-mediated chemical adsorption. These findings offered valuable insights for the comprehensive utilization of waste resources from the jujube industry in Xinjiang and highlighted the potential of biochar in treating printing and dyeing wastewater.
