MnO nanoparticles have a wide range of applications, including catalytic abilities due to their oxygen reduction potential. Industrial processes and the burning of organic materials released PAHs into the biosphere which have adverse effects on living organisms when continually exposed. In this study, MnO nanoparticles were synthesized chemically using sodium thiosulphate as reducing agent. MnO nanoparticles were characterized using UV-visible adsorption spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR). A X-Ray Diffraction Spectrophotometer (XRD), a Scanning Electron Microscopy - Energy Dispersive X-Ray Analyzer (SEM-EDAX), and Dynamic Light Scattering (DLS) were used to identify the crystalline nature and particle size of the fabricated MnO nanoparticles. Batch adsorption studies were conducted to identify the optimal conditions for better benzene and pyrene adsorption from aqueous solution using MnO nanoparticles. They are also effective in degrading benzene and pyrene by batch adsorption as determined by their adsorption isotherms and kinetics.
MnO纳米颗粒有广泛的应用，包括因其氧还原电位而具有的催化能力。工业过程和有机材料的燃烧将多环芳烃释放到生物圈中，当生物体持续接触时，这些多环芳烃会对其产生不利影响。在本研究中，使用硫代硫酸钠作为还原剂通过化学方法合成了MnO纳米颗粒。利用紫外可见吸收光谱和傅里叶变换红外光谱（FTIR）对MnO纳米颗粒进行了表征。使用X射线衍射分光光度计（XRD）、扫描电子显微镜-能量色散X射线分析仪（SEM-EDAX）和动态光散射（DLS）来确定所制备的MnO纳米颗粒的晶体性质和粒径。进行了批量吸附研究，以确定使用MnO纳米颗粒从水溶液中更好地吸附苯和芘的最佳条件。根据其吸附等温线和动力学可知，它们通过批量吸附在降解苯和芘方面也很有效。
