چکیده
Abstract This study reports the systematic development of cyclodextrin magnetic biocomposite for remediation 4-nitrophenol from wastewater. Magnetic was synthesized by co-precipitation Fe 2+ and 3+ in presence NaOH treated pine-cone followed cross-linking with using epichlorohydrin, achieved an optimization tool. The experiments were designed interaction between working condition variables (CM-CD mass, MNP time temperature) on % iron content 4-NP adsorption capacity optimized response surface methodology approach. temperature mass both have positive influences capacity. Crosslinking onto magnetite confirmed transmission electron microscopy, x-ray diffraction, vibrating scanning magnetometer, Fourier transform infrared spectroscopy thermal gravimetric analysis). Optimum conditions MNP-EPI-CD 2.0 g CM-β-CD, 0.83 at 30 °C 7.40 h which can remove 15.32 mg/g 4-nitrophenol. Graphical abstract

Response Surface Methodology for Optimizing Adsorption Process Parameters of Amaranth Removal Using Magnetic Layer Double Hydroxide (Fe3O4/ZnFe-LDH)
ABSTRACT Response surface methodology was employed to optimize the adsorption parameters of Amaranth onto magnetic layer double hydroxide (Fe3O4/ZnFe-LDH). Such optimization was undertaken to ensure a high efficiency over the experimental ranges employed, and to evaluate the interactive effects of the initial concentration of Amaranth, pH, adsorbent dosage, temperature and contact time on...

Nano-structured sphene (CaTiSiO5) powder was synthesized via mechanical activation and heat treatment method. The synthesized powder was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and simultaneous thermal analysis (STA). The sphene scaffolds were then fabricated via porogen method (using citric acid). Response surface methodology was successfully used to d...
متن کاملRapid Adsorption of Heavy Metals by Fe3O4/Talc Nanocomposite and Optimization Study Using Response Surface Methodology
Fe3O4/talc nanocomposite was used for removal of Cu(II), Ni(II), and Pb(II) ions from aqueous solutions. Experiments were designed by response surface methodology (RSM) and a quadratic model was used to predict the variables. The adsorption parameters such as adsorbent dosage, removal time, and initial ion concentration were used as the independent variables and their effects on heavy metal ion...
