Evaluation of natural goethite on the removal of arsenate and selenite from water

引用

Journal of Environmental Sciences 2019年第2期31卷 133-141页

作者： Andrew T.jacobson Maohong Fan Department of Chemical Engineering University of Wyoming

Elevated arsenic and selenium concentrations in water cause health problems to both humans and wildlife. Natural and anthropogenic activities have caused contamination of these elements in waters worldwide, making the development of efficient cost-effective methods in their removal essential. In this work, removal of arsenate and selenite from water by adsorption onto a natural goethite(α-FeO OH) sample was studied at varying conditions. The data was then compared with other arsenate, selenite/goethite adsorption systems as much of literature shows discrepancies due to varying adsorption conditions. Characterization of the goethite was completed using inductively coupled plasma mass spectrometry, X-ray diffraction, Fouriertransform infrared spectroscopy, scanning electron microscopy, and Brunauer–Emmett–Teller surface area analysis. Pseudo-first order(PFO) and pseudo-second order(PSO) kinetic models were applied; including comparisons of different regression methods. Various adsorption isotherm models were applied to determine the best fitting model and to compare adsorption capacitates with other works. Desorption/leaching of arsenate and selenite was studied though the addition of phosphate and hydroxyl ions. Langmuir isotherm modeling resulted in maximum adsorption capacities of 6.204 and 7.740 mg/g for arsenate and selenite adsorption,respectively. The PSO model applied with a non-linear regression resulted in the best kinetic fits for both adsorption and desorption of arsenate and selenite. Adsorption decreased with increasing pH. Phosphate induced desorption resulted in the highest percentage of arsenate and selenite desorbed, while hydroxide induced resulted in the fastest desorption kinetics.

The Bloomsbury Short Story

引用

Fudan Journal of the Humanities and Social Sciences 2017年第1期10卷 5-19页

作者： ira Nadel Department of English University of British Columbia 397 1873 East Mall VancouverBC V6T 1Z1 Canada

This article examines the importance of the short story form for the Bloomsbury writers and how their aesthetic theories influenced its composition, structure and content. Often overlooked in the history of the genre, the Bloomsbury short story has a claim to be an important aspect of the twentieth-century accounts of the short story form. Attention to Virginia and Leonard Woolf, Katherine Mansfield, Vita Sackville- West, E.M. Forster and others, such as Arnold Bennett and D.H. Lawrence, indicates their widespread engagement with the genre and the ways in which they treated it from fragmented conversation, as in Woolf s ＂The String Quartet,＂ to Foster＇s employment of linear narrative detail in ＂The Road from Colonus.＂ Formal experiments with syntax, imagery, and vocabulary and prose rhythm exhibit the seriousness of the short story for Bloomsbury authors. The influence of the Russians is particularly important with Che- kov dominating the reading and writing of Woolf, Mansfield, Lawrence and others. The very form of publication--mostly journals and magazines--is also crucial in shaping the length and structure of the short story. Attention to experimentation, as well as renewal, of the genre balances the impact of the short story on writers today and the question of a successor to the efforts and achievements of Bloomsbury＇s authors. A reading of the short stories of Julian Barnes explores this possibility.

American Roth

引用

Fudan Journal of the Humanities and Social Sciences 2019年第3期12卷 493-510页

作者： ira Nadel Department of English University of British Columbia 397-1873 East Mall Vancouver BC V6T 1Z1 Canada

An analysis of the Philip Roth's sustained pursuit of his American identity mixed with his engagement with the trope of the American Adam is the center of this paper. From the outset of his career, Roth has sought to be understood as an American, not Jewish, writer. But as his career unfolded, the challenges of sustaining his American identity grew, whether in Portnoy's Complaint, Sabbath's Theatre or the American Trilogy. The confrontation between American and Judaic identities increasingly became his subject as his Jewish roots threatened his American identity stemming from a Protestant, if not Puritan, literary heritage. Coleman Silk and Swede Levov from The Human Stain and American Pastoral represent the challenge best summarized by Abe Ravelstein in Bellow's eponymous novel when he remarks that “as a Jew you are also an American, but somehow you are not.” The paradox of Roth’s entanglement with the trope of the American Adam is that he both pursues and denies this identity, accepting its heroism but acknowledging its impossibility. One moment he publically declares “if I’m not an American, I am nothing,” but on the other, to be Roth he knows he must violate the Adamic ideal, prepared to renounce neither his American nor Jewish identities.

Dactyls and Pterodactyls： New Convergences of Poetics and Science

引用

Frontiers of Literary Studies in China-Selected Publications from Chinese Universities 2013年第2期7卷 287-304页

作者： ira Livingston Humanities & Media Studies Pratt Institute Main Brooklyn Campus New York NY 11205 USA

If poetics refers broadly to the principles by which things are made, how is the kind of process that yields poetry （in the narrow sense） related to other kinds of making？ This essay explores promising resonances between traditional poetics and new paradigms coming out of complexity and systems theory. Of particular interest is Terrence Deacon＇s Incomplete Nature, an account of the relationships among layers of emergent order in the universe, under the heading of a general theory of dynamics. In particular, this essay understands poetry in relation to other kinds of making through three principles Deacon identifies as crucial： constraint, emergence, and absence. These principles tend to validate rather than to undermine traditional accounts of poetic making as inspiration, often involving entification in the form of attribution of creative agency to entities such as muses or to the text itself.

关键词： absentiality constraint Terrence Deacon emergence entification,incomplete nature poetics.

Synthesis and Structures of A Series of Novel Rare Earth Transition Metal Sulfates

引用

Journal of Rare Earths 2006年第6期24卷 659-662页

作者：王希渠刘鲁美 Allan J.jacobson Department of Chemistry and Texas Center for Superconductivity University of Houston Houston TX 77204-5003USA

Seven new rare earth transition metal sulfates were synthesized by hydrothermal reactions under conditions slightly above the critical point of water. Their crystal structures were determined from single crystal X-ray data. The compositions of the new compounds can be represented by two general formulae ： REM （OH） 3 （SO4） and RE2M （OH） 3 （SO4） 2F （H2O） with RE = Gd, Tb, Dy ; M = Ni, Cu. Three different crystal structure types were found for the formula REM （OH） 3 （SO4）. The structures of the new compounds all feature infinite chains of REOn coordination polyhedra, which are connected to chains of CuO6 or NiO6 octabedra. The limited size range of the rare earth cations observed in these compounds is most likely because of interactions between the octabedral chains and the chains of REOn polyhedra. The new compounds are closely related to the known yttrium transition metal sulfates.
