INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5.

Materials based on the pillared cyano-bridged architecture, [Ni’(L)Ni(CN)4]n (L = pillar organic ligands), also known as PICNICs, have been shown to be especially diverse where pore size and pore functionality can be varied by the choice of pillar organic ligand. In addition, a number of PICNICs form soft porous structures that show reversible structure transitions during the adsorption and desorption of guests. The structural flexibility in these materials can be affected by relatively minor differences in ligand design, and the physical driving force for variations in host-guest behavior in these materials is still not known. One key to understanding this diversity is a detailed investigation of the crystal structures of both rigid and flexible PICNIC derivatives. This article gives a brief review of flexible MOFs. It also reports the crystal structures of five PICNICS from our laboratories including three 3-D porous frameworks (Ni-Bpene, NI-BpyMe, Ni-BpyNH2), one 2-D layer (Ni-Bpy), and one 1-D chain (Ni-Naph) compound.

Additionally, it was found that K. pneumoniae strain is not only able to degrade potassium cyanide, but also to degrade potassium hexacyano- ferrate(II) trihydrate and sodium ferrocyanide decahydrate with the effi ciencies of 85 and 87.5 %, respectively. Furthermore, this strain degraded potassium cyanide in the presence of diff erent ions such as magnesium, nickel, cobalt, iron, chromium, arsenic and zinc, in variable concentrations (0.1, 0.25 and 0.5 mM) and as a result the amount of the bacteria in the biodegradation media decreased with the increase of ion concentration. Lastly, it was also observed that sterile crude extract of K. pneumoniae strain degraded potassium cya- nide on the fi ft h day of incubation. Based on these results, it is concluded that both culture and sterile crude extract of K. pnemoniae will be used in cyanide removal from diff erent wastes.

They are 2NiCO3•3Ni(OH)2•4H2O [29863- 10-3], and NiCO3•2Ni(OH)2 [12607-70-4], MW 304.17. The second form occurs in nature as a tetrahydrate, mineral, zaratite. Commercial nickel car- bonate is usually the basic salt, 2NiCO3•3Ni(OH)2•4H2O. Uses Nickel carbonate is used to prepare nickel catalysts and several specialty compounds of nickel. It also is used as a neutralizing agent in nickel plating solutions. Other applications are in coloring glass and in the manufacture of ceramic pigments. Physical Properties NiCO3: Light green rhombohedral crystals; decomposes on heating; practi- cally insoluble in water, 93 mg/L at 25°C; dissolves in acids. 2NiCO3•3Ni(OH)2•4H2O: Light green crystals or brown powder; decom- poses on heating; insoluble in water; decomposes in hot water; soluble in acids and in ammonium salts solutions. Zaratite: Emerald greed cubic crystals; density 2.6 g/cm3; insoluble in water; soluble in ammonia and dilute acids. Thermochemical Properties ∆Ηƒ° (NiCO3) –140.6 kcal/mol Preparation Anhydrous nickel carbonate is produced as a precipitate when calcium car- bonate is heated with a solution of nickel chloride in a sealed tube at 150°C. Alternatively, treating nickel powder with ammonia and carbon dioxide fol- lowed by boiling off ammonia yields pure carbonate. When sodium carbonate is added to a solution of Ni(II) salts, basic nickel carbonate precipitates out in impure form.

  • Solvent Extraction of Copper and Cyanide from Waste Cyanide Solution
    SOLVENT EXTRACTION OF COPPER AND CYANIDE FROM WASTE CYANIDE SOLUTION by FENG XIE B. Sc., The Northeastern University (PRC), 1992 M. Sc., The Northeastern University (PRC), 1995 M. A. Sc., The University of British Columbia, 2005 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE STUDIES (Materials Engineering) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) April 2010 © Feng Xie, 2010 ABSTRACT The potential use of two commercial extractants, LIX 7950, a guanidine derivative, and LIX 7820, a solvent mixture of quaternary amine and nonylphenol, for recovery of copper and cyanide from waste cyanide solution has been investigated. Low equilibrium pH favors copper extraction while a high molar ratio of cyanide to copper depresses the copper loading. It is confirmed that Cu(CN)32 is preferentially extracted over Cu(CN)43 and CN by the extractants. Solvent extraction of the mixture of metal cyano complexes shows a selectivity order as follows: Zn > Ni > Cu > Fe. The presence of S042 or S203 shows an insignificant effect on copper extraction while SCN ions may potentially compete for the available extractant with copper cyanide species and thus depress copper extraction significantly. Both extractants exhibit an affinity sequence as SCN > CNO > CN> S203. The selectivity order of different anions with the extractants can be explained by the interrelated factors including anion hydration, charge density, compatibility of the formed complex with the organic phase and the geometry effect. The extraction of Cu(CN)32 with LIX 7950 is exothermic with an enthalpy change (AH°) of -191 kJ/mol.
