Abstract

Dyes are commonly used in the production of textiles such as clothes, towels, and carpets. However, during the Manufacturing process, approximately 5% to 15% of these substances are lost and discarded. If the wastewater containing these dyes is released without proper treatment, it can lead to significant environmental damage and public health concerns. Among the various methods available for decontaminating textile effluents, adsorption has proven to be particularly effective. This study investigates the use of Mimosa caesalpiniifolia wood powder as a biosorbent for the removal of methylene blue (MB) dye from aqueous solutions. The wood powder underwent both hot and cold extraction processes to remove extractives. The biosorbent was characterized using Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and Zero Charge Potential (ZPC) analysis. Subsequently, experiments were conducted to study dye degradation, the effects of pH, adsorption kinetics, and adsorption isotherms. The pH tests revealed that the highest MB dye adsorption occurred in alkaline conditions. The kinetic study determined an equilibrium time of 120 min with a dye removal efficiency of 96.98% ± 0.052%. Among the kinetic models tested, the pseudo-second-order model provided the best fit, with a Maximum adsorption capacity of 12.140 mg·g⁻¹. Regarding the isothermal models, the Langmuir model showed the best fit, with Maximum adsorption capacities of 39.623, 42.189, and 43.783 mg·g⁻¹ at temperatures of 28 °C, 38 °C, and 48 °C, respectively. These findings demonstrate that Mimosa caesalpiniifolia wood powder is an efficient and sustainable adsorbent for methylene blue removal, with potential applications in wastewater treatment.

含羞草木高效吸附去除亚甲基蓝染料

染料通常用于生产纺织品，如衣服、毛巾和地毯。然而，在生产过程中，这些物质中约有5%至15%丢失和丢弃。如果未经适当处理就排放含有这些染料的废水，可能会导致严重的环境破坏和公共健康问题。在各种可用于净化纺织废水的方法中，吸附已被证明是特别有效的。研究了含羞草木粉作为生物吸附剂对亚甲基蓝（MB）染料的去除效果。木粉经过冷热两种提取工艺去除萃取物。利用扫描电镜（SEM）、傅里叶红外光谱（FTIR）和零电荷电位（ZPC）分析对该生物吸附剂进行了表征。随后，对染料降解、pH、吸附动力学和吸附等温线的影响进行了实验研究。pH值测试表明，碱性条件下对MB染料的吸附量最高。动力学研究确定了平衡时间为120 min，染料去除率为96.98%±0.052%。拟二级吸附模型拟合效果最好，最大吸附量为12.140 mg·g−1。Langmuir模型在28℃、38℃和48℃条件下的最大吸附量分别为39.623、42.189和43.783 mg·g−1。上述结果表明，含羞草木粉是一种高效、可持续的亚甲基蓝吸附剂，在废水处理中具有潜在的应用前景。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
