Adsorptive removal of dyes from synthetic and real textile wastewater using magnetic iron oxide nanoparticles: Thermodynamic and mechanistic insights

20-Aug-2015 | Nashaat N. Nassar, Nedal N. Marei, Gerardo Vitale, Laith A. Arar, The Canadian Journal of Chemical Engineering, 2015

Abstract Magnetic iron‐oxide nanoparticles exhibit high efficiency in wastewater treatment for many important reasons, including that they can remove contaminants from wastewater rapidly owing to their high external surface area/unit mass and interstice reactivity. Additionally, this type of ...

An efficient non‐Newtonian fluid‐flow simulator for variable aperture fractures

19-Aug-2015 | Joseph P. Morris, Gocha G. Chochua, Andrey V. Bogdan, The Canadian Journal of Chemical Engineering, 2015

Abstract Many natural and industrial applications involve non‐Newtonian fluids with high effective viscosity ratios flowing between surfaces with spatial variations in aperture. In particular, hydraulic fracturing operations often require pumping sequences of non‐Newtonian fluids with ...

Wire‐coating by withdrawal from a bath of Phan‐Thien‐Tanner fluid

12-Aug-2015 | Muhammad Asif Javed, Nasir Ali, Tasawar Hayat, The Canadian Journal of Chemical Engineering, 2015

In this paper, the problem of coating wire by withdrawing it from a bath of Phan‐Thien‐Tanner (PTT) fluid is investigated. The problem is analyzed using (a) the complete form of the Phan‐Thien‐Tanner (PTT) constitutive equation with a linearized version of the stress coefficient; and (b) the ...

Kinetics of catalytic oxidation of sulphite in diluted aqueous solutions

07-Aug-2015 | Michal Opletal, Petr Novotný, František J. Rejl, Tomáš Moucha, Michal Kordač, Chemical Engineering & Technology, 2015

Abstract Catalyzed reaction of sulfite with oxygen is often used by industry for corrosion protection by chemical deoxygenation. The same reaction system is considered very important as a part of atmospheric chemistry due to SO2 immission modeling. In these applications, reaction kinetic data ...

Combined heat and mass transfer of third‐grade nanofluids over a convectively‐heated stretching permeable surface

30-Jul-2015 | W. A. Khan, J. R. Culham, O. D. Makinde, The Canadian Journal of Chemical Engineering, 2015

Abstract The buoyancy‐induced flows of third‐grade nanofluids are investigated along a vertical permeable stretching sheet, and a numerical solution is obtained for the combined heat and mass transfer during convective cooling of the stretching sheet, subject to partial slip and convective ...

Fabrication of polyvinyl chloride based nanocomposite nanofiltration membrane: investigation of SDS/Al2O3 nanoparticle concentration and solvent ratio effects

21-Jul-2015 | E. Bagheripour, A. R. Moghadassi, S. M. Hosseini, Asia-Pacific Journal of Chemical Engineering, 2015

Abstract In the current research polyvinylchloride‐based nanocomposite nanofiltration membranes were prepared by using of sodium dodecyl sulfate (SDS) as additive, aluminum oxide (Al2O3) nanoparticles as inorganic filler and dimethylacetamide (DMAC)/tetrahydrofuran (THF) as solvents via phase ...

Impact of electrospinning process parameters on the measured current and fiber diameter

17-Jul-2015 | Siavash Sarabi‐Mianeji, Jennifer Scott, Danny J.Y.S. Pagé, Polymer Engineering and Science, 2015

In this article, polycaprolactone (PCL) nanofibres were processed by electrospinning using a 3:1 ratio of tetrahydrofuran to methanol as solvent. The solvent choice was motivated by the possibility of greener alternatives to the halogenated compounds most often used for electrospinning. The ...

Photoelectrocatalytic oxidation of methyl orange on TiO2 nanotubular anode using a flow‐cell

03-Jul-2015 | María José Martín de Vidales, Laura Mais, Cristina Sáez, Pablo Cañizares, Frank C. Walsh, Manuel A. Rodrigo, Christi ..., Chemical Engineering & Technology, 2015

Abstract Methyl orange from water was removed by photocatalytic anodic oxidation method using a titanium dioxide array surface. The coating was prepared by anodising a titanium plate using NH4F as electrolyte followed by heat treatment to render a photocatalytic surface under UV light. SEM ...

Solvent extraction of phenol from aqueous solution with benzyl 2‐ethylhexyl sulfoxide as a novel extractant

03-Jul-2015 | Shixiong Wang, Deqiang Shi, Ruisi Yang, Yan Xu, Hong Guo, Xiangjun Yang, The Canadian Journal of Chemical Engineering, 2015

In this paper, we synthesized a novel structure of sulfoxide, benzyl 2‐ethylhexyl sulfoxide (BSO), and evaluated its performance for extracting phenol. The influences of several variables on phenol extraction were investigated, including equilibrium time, pH value, temperature, and salts in the ...

Performances of poly(vinylidene fluoride‐co‐hexafluoropropylene) ultrafiltration membranes modified with poly(vinyl pyrrolidone)

30-Jun-2015 | P. Kanagaraj, A. Nagendran, D. Rana, T. Matsuura, S. Neelakandan, R. Revathi, N. Pandiyarajan, Polymer Engineering and Science, 2015

The structure and performance of modified poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVdF‐co‐HFP) ultra‐filtration membranes prepared from casting solutions with different concentrations of poly(vinyl pyrrolidone) (PVP) were investigated in this study. Membrane properties were studied in ...
