This paper reports an investigation into the effect of a number of operating factors on the removal of Acid Blue 92 (AB92) from an aqueous solution using hydroxyl-terminated polybutadiene (HTPB) as an adsorbent. The optimum values of adsorbent dose and pH were found to be 35mgL(-1) and 6, respectively. Temperature showed a significant effect, with maximum dye removal being observed at 45°C. Stirring the solution during the treatment process resulted in significant removal improvement. The Langmuir adsorption model was used to quantify the amount of AB92 adsorbed on the surface of HTPB. FT-IR spectrometry results for HTPB, AB92, and HTPB-AB92 verified the efficiency of the treatment. Further, the adsorbent was characterized using SEM and H NMR techniques.
本论文报道了一项研究,考察了多种操作因素对使用端羟基聚丁二烯(HTPB)作为吸附剂从水溶液中去除酸性蓝 92(AB92)的影响。结果发现,吸附剂剂量和 pH 的最佳值分别为 35mgL(-1)和 6。温度有显著影响,在 45°C 时观察到最大的染料去除率。在处理过程中搅拌溶液可显著提高去除效果。Langmuir 吸附模型用于量化 HTPB 表面吸附的 AB92 量。FT-IR 光谱法对 HTPB、AB92 和 HTPB-AB92 的结果验证了处理的效率。此外,还使用 SEM 和 H NMR 技术对吸附剂进行了表征。
