The synthesis, characterization, and methylene blue (MB) adsorption study of a new lignosulfonate/amino-functionalized SBA-15 nanocomposite are described. (3-Aminopropyl)triethoxysilane (APTES) was grafted into SBA-15 to prepare amino-functionalized SBA-15 (N-SBA-15) which was used, along with calcium lignosulfonate (LS), to prepare a new nanocomposite LS/N-SBA-15. The prepared materials were characterized by SEM, TEM, FT-IR, Brunauer–Emmett–Teller, powder XRD, TGA analysis, and Raman spectroscopy. The experimental results indicated that the obtained nanocomposite possesses a high surface area (598 m2 g−1) and a large pore volume (1.059 cm3 g−1). This particular combination of LS and N-SBA-15 endowed this material with good dispersibility and stability in water, and better wettability. The uptake of MB from aqueous solution using the LS/N-SBA-15 nanocomposite was investigated. The adsorption investigation was performed under parameters such as pH, contact time, adsorbent dosage, temperature and initial dye concentration. The results indicated that the addition of LS to N-SBA-15 enhanced the stability of the composite in water, and improved its adsorption capacity of MB, and showed the optimum conditions at 0.05 g dose and pH = 9 during a short contact time less than 10 min. LS/N-SBA-15 exhibited a high adsorption capacity compared to other adsorbents used in the literature for the removal of MB from water. The reusability of this new nanocomposite was also investigated and the results reported. This new nanocomposite can be efficiently employed for the removal of organic dyes from wastewater.

木质素磺酸盐/氨基官能化SBA-15纳米复合材料的合成及表征
描述了一种新的木质素磺酸盐/氨基官能化的SBA-15纳米复合材料的合成，表征和亚甲基蓝（MB）吸附研究。将（3-氨基丙基）三乙氧基硅烷（APTES）接枝到SBA-15中以制备氨基官能化的SBA-15（N-SBA-15），与木质素磺酸钙（LS）一起用于制备新的纳米复合材料LS / N -SBA-15。通过SEM，TEM，FT-IR，Brunauer-Emmett-Teller，粉末XRD，TGA分析和拉曼光谱对制备的材料进行表征。实验结果表明，所得纳米复合材料具有高表面积（598m 2 g -1）和大孔容（1.059 cm 3 g -1）。）。LS和N-SBA-15的这种特殊组合赋予该材料在水中良好的分散性和稳定性，以及更好的润湿性。研究了使用LS / N-SBA-15纳米复合材料从水溶液中吸收MB的情况。在诸如pH，接触时间，吸附剂剂量，温度和初始染料浓度的参数下进行吸附研究。结果表明，将LS添加到N-SBA-15中可增强复合物在水中的稳定性，并提高其对MB的吸附能力，并在较短的接触时间内以0.05 g的剂量和pH = 9显示了最佳条件。超过10分钟 与文献中用于从水中去除MB的其他吸附剂相比，LS / N-SBA-15具有较高的吸附能力。还研究了这种新的纳米复合材料的可重用性，并报告了结果。这种新的纳米复合材料可以有效地用于去除废水中的有机染料。
