摘要

目前的研究旨在设计和组装一种新型的纳米生物复合材料，通过微波辐照将碳化钼（Mo2C），铁酸锌（ZnFe2O4）和生成的石榴皮纳米炭（PPNB）结合形成MoC-ZnFe2O4@PPNB。本研究旨在探索其在去除水生系统中作为新兴污染物的阿霉素方面的潜在实施。根据Mo、Zn、Fe、C、O等相关元素的存在度，通过EDX和XPS评价确定了MoC-ZnFe2O4@PPNB的元素组成，分别为6.11%、3.66%、5.64%、17.04和67.55%。HR-TEM在5.44 ~ 12.77 nm处检测到MoC-ZnFe2O4@PPNB粒子，其零电荷点在pH值为5.8处。在pH为6.0、反应时间为30.0 min、纳米复合材料用量为15.0 mg的条件下，MoC-ZnFe2O4@PPNB对DOX污染物的吸附回收率进行了广泛优化。非线性卡方检验（X2）和误差平方和（ERRSQ）验证了拟二阶模型的有效性，Freundlich表达式被认为是最方便的等温线模型。热力学研究是指DOX通过放热反应吸附到MoC-ZnFe2O4@PPNB上的自发性。MoC-ZnFe2O4@PPNB在连续5次循环中表现出优异的循环稳定性，在第5次再生后，去除率下降了5.7 - 6.3%。此外，MoC-ZnFe2O4@PPNB对污染水样中DOX的回收率达到93.4 - 96.7%（自来水），92.9 - 95.5%（废水）和88.6 - 91.3%（海水），具有优异的回收率。因此，经过验证的MoC-ZnFe2O4@PPNB去除DOX的结果表明，该纳米生物复合材料具有高吸附能力、可再生性和在真实水基质中的高效应用，在去除真实水中DOX药物污染物方面表现优异。

Insight into optimization of doxorubicin removal by a novel nanobiocomposite of doped molybdenum carbide and zinc ferrite onto pomegranate peels nanobiochar (Mo2C-ZnFe2O4@PPNB)

The current investigation is directed to design and assemble a novel nanobiocomposite by the facile microwave irradiation for binding of molybdenum carbide (Mo₂C), zinc ferrite (ZnFe₂O₄) and generated pomegranate peels nanobiochar (PPNB) for the formation of MoC-ZnFe₂O₄@PPNB. This was then aimed to explore its potential implementation in removing doxorubicin drug as emerging pollutant from aquatic systems. The elemental composition of MoC-ZnFe₂O₄@PPNB was confirmed by the EDX and XPS evaluations referring to the existence of various related elements as Mo, Zn, Fe, C, and O with 6.11, 3.66, 5.64, 17.04 and 67.55 %, respectively. The HR-TEM detected the MoC-ZnFe₂O₄@PPNB particles at 5.44–12.77 nm and the point of zero charge was characterized at pH 5.8. MoC-ZnFe₂O₄@PPNB was extensively optimized in adsorptive recovery of DOX pollutant under diverse experimental conditions providing pH 6.0, 30.0 min reaction time and 15.0 mg nanobiocomposite dosage. The nonlinear chi-square test (X²) and sum of squares of errors (ERRSQ) confirmed best validation to the pseudo-second order model, while Freundlich expression was identified as the most convenient isotherm model. The thermodynamics investigation referred to the spontaneity of DOX adsorption onto MoC-ZnFe₂O₄@PPNB via exothermic reaction. MoC-ZnFe₂O₄@PPNB exhibited excellent recycling stability for five consecutive cycles providing 5.7–6.3 % declining in the removal efficiency after the fifth regeneration process. Moreover, MoC-ZnFe₂O₄@PPNB was identified with excellent capability for recovery of DOX from contaminated water samples by reaching up to 93.4–96.7 % (tap water), 92.9–95.5 % (wastewater) and 88.6–91.3 (sea water). Therefore the outcomes of DOX removal by the testified MoC-ZnFe₂O₄@PPNB are pointing out to the outstanding behavior of this nanobiocomposite in decontamination of DOX drug pollutant from real waters based on the characterized high adsorption capability, regenerability and efficient application in real water matrices.

期刊介绍： The journal includes papers in the following areas: – Simple organic liquids and mixtures – Ionic liquids – Surfactant solutions (including micelles and vesicles) and liquid interfaces – Colloidal solutions and nanoparticles – Thermotropic and lyotropic liquid crystals – Ferrofluids – Water, aqueous solutions and other hydrogen-bonded liquids – Lubricants, polymer solutions and melts – Molten metals and salts – Phase transitions and critical phenomena in liquids and confined fluids – Self assembly in complex liquids.– Biomolecules in solution The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include: – Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.) – Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.) – Light scattering (Rayleigh, Brillouin, PCS, etc.) – Dielectric relaxation – X-ray and neutron scattering and diffraction. Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
