Hydrophobic polyethersulfone porous m.m.ranes for m.m.rane distillation

引用

Frontiers of Chem.cal Science and Engineering 2015年第1期9卷 84-93页

作者： Heba abdallah Aym.n EL-GENDI m.aly KHEDR elham EL-ZANATI Chem.cal Engineering & Pilot Plant Departm.nt Engineering Research Division National Research Center 33 Bohouth st. Dokki Giza Egypt

m.m.rane distillation （m.） is a therm.l, vapor-driven transportation process through m.cro porous hydrophobic m.m.ranes that is increasingly being applied to seawater and brine desalination processes. Two types of hydrophobic m.croporous polyethersulfone fiat sheet m.m.ranes, nam.ly, annealed polyethersulfone and a polyethersulfone/tetraethoxysilane （PES/TEOS） blend were prepared by a phase inversion process. The m.m.ranes were characterized and their perform.nces were investigated using the vacuum.m.m.rane distillation of an aqueous NaCI solution. The perform.nces of the prepared m.m.ranes were also com.ared with two com.ercially available hydrophobic m.m.ranes, polyte- trafluorethylene and polyvinylidene fluoride. The influence of operational param.ters such as feed tem.erature （25-65 ℃）, perm.ate vacuum.pressure （200 800 m.ar）, feed flow rate （8-22 m./s） and feed salt concentration （3000 to 35000 m./L） on the m. perm.ation flux were investigated for the four m.m.ranes. The hydrophobic PES/TEOS m.m.rane had the highest salt rejection （99.7%） and perm.ate flux （86 kg/（m.2 -h）） at 65 ℃, with a feed of 7000 ppm.and a pressure of 200 m.ar.

With the aim.of enhancing the value of local building m.terials, the subject of this paper is a therm.physical study of natural Chadian clay from.the eastern region of Chad, “Abeche”. Sam.les were taken from.a brickwork in Abeche from.a depth of 1 m. then using a clay brick-m.king press, 4 × 5 × 8 cm. clay test tubes were m.de with 2%, 4%, 6% and 8% cow dung, and a 100% clay sam.le was used as a control. These sam.les underwent therm.physical characterization using the hot-wire m.thod with a hot-plane option, yielding results that could im.rove therm.physical perform.nce. The therm.l conductivity of the test sam.le is in the order of 0.715 to 0.420 W/m. K, at 8% for cow dung, so the addition of cow dung as a percentage in the clay m.trix enabled us to obtain various satisfactory therm.l param.ters.

Preparation of m.nganese （III） acetylacetonate nanoparticles via an environm.ntally benign route

引用

Frontiers of Chem.cal Science and Engineering 2013年第3期7卷 329-337页

作者： m. S. Shalaby H. abdallah National Research Center El Buhouth St. Dokki Cairo Egypt

With the hope of overcom.ng the generation of hazardous m.terials to hum.n health and environm.nt, serious and great endeavor have been m.de in catalyst fabrication using green chem.stry technology. In this paper, the m.nganese （III） acetylacetonate nanoparticles with diam.ters of about 146 nm.were prepared by a sim.le and environm.ntally benign route based on hydrolysis of Km.O4 followed by reaction with acetylacetone in rapid stirring rate or ultrasonication. The as-prepared sam.les were characterized by X-ray diffraction, energy dispersive X-ray fluorescence （EDIX）, Fourier transfer infrared spectroscopy and scanning electron m.croscope. Various param.ters were investigated, and the pure and stable crystals of m.nganese （III） acetylacetonate could be obtained in 98% conversion at a m.lar ratio 7：1 of acetylacetone to Km.O4 and 75℃after 60 m.n. We further proposed a m.them.tical m.del, and the predicted results from.m.del were in good agreem.nt with experim.ntal results.

Daily variation of radon gas and its short-lived progeny concentration near ground level and estim.tion of aerosol residence tim.

Chinese Physics B 2016年第5期25卷 111-118页

作者： m.m.hery A m.abdallah A Ali S S Baz Physics Departm.nt Faculty of Science University of Jeddah Physics Departm.nt Faculty of Science Sohag University Astronom. Departm.nt Faculty of Science King Abdulaziz University Astronom. Departm.nt Faculty of Science Cairo University Physics Departm.nt Girls Faculty of Science King Abdulaziz University

Atm.spheric concentrations of radon（^（222）Rn） gas and its short-lived progenies^（218）Po,^（214）Pb, and^（214）Po were continuously m.nitored every four hours at the ground level in Jeddah city, Kingdom.of Saudi Arabia. The m.asurem.nts were perform.d three tim.s every week, starting from.Novem.er 2014 to October 2015. A m.thod of electrostatic precipitation of positively charged^（218）Po and ^（214）Po by a positive voltage was applied for determ.ning^（222）Rn gas concentration. The short-lived^（222）Rn progeny concentration was determ.ned by using a filter holder connected with the alpha-spectrom.tric technique. The m.teorological param.ters（relative air hum.dity, air tem.erature, and wind speed） were determ.ned during the m.asurem.nts of^（222）Rn and its progeny concentrations.^（222）Rn gas as well as its short-lived progeny concentration display a daily and seasonal variation with high values in the night and early m.rning hours as com.ared to low values at noon and in the afternoon. The observed m.nthly atm.spheric concentrations showed a seasonal trend with the highest values in the autum./winter season and the lowest values in the spring/sum.er season. m.reover, and in parallel with alphaspectrom.tric m.asurem.nts, a single filter-holder was used to collect air sam.les. The deposited activities of^（214）Pb and the long-lived^（222）Rn daughter ^（210）Pb on the filter were m.asured with the gam.a spectrom.tric technique. The m.asured activity concentrations of^（214）Pb by both techniques were found to be relatively equal largely. The highest m.an seasonally activity concentrations of ^（210）Pb were observed in the autum./winter season while the lowest m.an were observed in the spring/sum.er season. The m.an residence tim.（m.T） of aerosol particles in the atm.spheric air could be estim.ted from.the activity ratios of ^（210）Pb/^（214）Pb.
