Abstract

The removal of Ni²⁺ ions from the effluent of the paper mill was accomplished by using magnesium ferrite nanoparticles. The nanoparticles were produced through a sol–gel process at low temperatures. Experimental factors were meticulously optimized to enhance the adsorption process. Optimal conditions were determined to be 1.0 mL of buffer solution with a pH of 8.0, 100 mg of nano-sorbent, and mixing for 30 min. When these conditions were put to test, the removal efficiency was enhanced to ≥ 98.4%. Additionally, it was discovered that the nanoparticles exhibit exceptional reusability upon regeneration after the first use. The investigation of adsorption equilibrium was conducted utilizing the Langmuir, Freundlich, and Sips models. The Sips isotherm demonstrated the strongest correlation with the experimental results, as indicated by the coefficient of determination (R²) of 0.9976 while the reaction order was estimated as 1.61 by the kinetic model.

铁氧体镁纳米吸附剂去除造纸废水中镍（II）的快速有效方法：方法开发、可重复使用、等温模型和吸附动力学

采用铁酸镁纳米颗粒对造纸废水中的Ni2+离子进行了脱除。纳米颗粒通过低温溶胶-凝胶法制备。对实验因素进行了优化，提高了吸附效果。最佳条件为1.0 mL pH = 8.0的缓冲液，加入100 mg纳米吸附剂，搅拌30 min。实验结果表明，该条件下的去除率可达98.4%以上。此外，研究发现，纳米颗粒在第一次使用后再生时表现出优异的可重复使用性。利用Langmuir， Freundlich和Sips模型对吸附平衡进行了研究。Sips等温线与实验结果的相关性最强，决定系数（R2）为0.9976，动力学模型估计反应级数为1.61。

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
