Mussel Incubation Method for Monitoring Organochlorine Compounds in Freshwater Recipients of Pulp and Paper Industry
Author: Sirpa Herve

ISBN:
Category : Biological monitoring
Languages : en
Pages : 158
Book Description
Academic dissertation for the degree of Doctor of Philosophy. A biological method based on bioaccumulation and using incubated lake mussels was developed and applied for monitoring organic chlorocompounds originating especially from pulp and paper industry and occuring in the water in very small and fluctuating concentrations. Analysis of bleaching remanants from incubated mussels seemed to be very suitable for the monitoring of organochlorine compounds originating in the pulp and paper industry.

X-ray Structural Studies of Some Group VIII Compounds with Catalytic Implications
Author: Douglas Allen Sullivan
Publisher:
ISBN:
Category : Metals
Languages : en
Pages : 474
Book Description
X-ray structural investigations of compounds containing Group VIII metal atoms are presented. The compounds studied illustrate interatomic interactions which may be of importance in catalytic processes. The structures of metal-containing compounds were solved by locating the heavy atoms in Patterson functions and locating the remaining atoms in Fourier syntheses. The direct method of symbolic addition was used in the one, all light-atom case presented. Trial structures were refined by the method of least-squares. The crystal structure of trans -chloro (dimethylglyoximato) (dimethylglyoxime) (4-chloroaniline) cobalt (III) illustrates an unusual ligand-induced proton shift. Both neutral and dianionic dimethylglyoxime groups are found in the complex and the 4-chloroaniline ligand is oriented over the dianionic dimethylglyoxime. The structure of trans-bis (dimethylxiglyoximato) bis (4-chloroaniline) cobalt (III) chloride shows that complex to contain two monoatomic dimethylglyoxime ligands and the 4-chloroaniline ligands to be skewed relative to the diglyoxime ligands. The crystal structure of trans-chlorobis (diphenylglyoximato) {4-chloroaniline) cobalt- (III) is described. Trends in the structures of these compounds and in the previously reported structures of similar compounds are discussed. Ultraviolet and infrared spectra of these compounds are given. The synthesis of a novel chelating ligand capable of binding two metal ions is described. The characterizations, including crystal structures, of its protonated forin, 1,4-dihydrazinophthalazinebis (2-pyridiniuracarboxaldimine) nitrate dihydrate, and of a nickel complex, y-chlorotetraaqua .,4- dihydrazinophthalazinebis (2-pyridinecarboxaldimine) dinickel- (II) chloride dihydrate, are presented. The planar ligand is shown to bind tv/o nickel ions with a separation of 3. COS o (1) A.A chloride ion occupies a bridging site in the plane of the nickel atoms and the ligand. The magnetic moment per nickel atom of the chloride bridged complex was deteinnined to be 2.74 B.M. at 40°C. The plausibility of structurally similar complexes mimicking the nitrogen-fixing enzyme nitrogenase is also discussed. The X-ray crystal structures of 1- (ir-cyclopentadienyl) - l-triphenylphosphine-2,3,4, 5-tetrakis (pentaf luorophenyl) cobaltole and 1- (Tr-cyclopentadienyl) -1-triphenylphosphine- 2,3, 4, 5-tetrakis (pentaf luorophenyl) rhodole are reported. These compounds are viewed as stabilized intermediates in the catalyzed cyclization of acetylenes. In each case the metal atom forms a metallocyclo by a-bonding to the terminal carbons of a butadiene-like fragment. The ir-bonding in the metallocycle appears to be dclocalized.
