AbstractAbstract
[en] Complete text of publication follows. It is well established that certain types of chemical reactions, subject to appropriate conditions, organize themselves spontaneously to give rise to regular spatial patterns or to periodic rate fluctuations. In this work, the effects of non-aqueous solvents, non-ionic, cationic, and anionic surfactants, complexing agents, and organic base on the behavior of the 1, 10 phenanthroline chemiluminescence (CL) oscillating system were investigated. Oscillating CL produced by the addition of 1,10-phenanthroline to the oscillating system H2O2-KSCN-CuSO4-NaOH was investigated using luminometry method in a batch reactor. In the presence of solvent with high basicity compare to water, tetrahydrofuran (THF), the CL intensity was increased (11 fold), the light emitting and oscillating time was enhanced by 2-fold. In addition, the effect of surfactant, in the concentration range of 0.3-1.5 m/v, on oscillatory system was investigated. Non-ionic and anionic surfactants including triton X-100, triton X-114, brij 35 and sodium dodecyl sulfate (SDS) increased the intensity of the oscillating CL reaction by 32, 5, 10 and 6-folds, respectively. The effects of complexing agents including such as ethylenediaminetetraacetic acid (EDTA) and triethylenetetraamine (TETA) on oscillating CL system were investigated. The oscillating CL with organic base was also studied. Results indicated that using tetramethylammonium hydroxide, TMAOH, causes regular oscillating CL with nearly the same oscillating period compare to NaOH.

AbstractAbstract
[en] A continuous flow system has been developed to determine trace Cu(II), Mn(II), Ni(II) and Zn(II) in a large volume of water samples by a solvent sublation technique. The mixed solution of 1,10-phenanthroline(phen) and thiocyanate ion was used as ligands for the formation of their ternary complexes. The continuous system was constructed in this laboratory with a peristaltic pump, a mini shaker, three mixing bottles and a flotation cell by connecting each part with a polyethylene tube. The flotation conditions such as the flow rate of sample solution and the injection rates of ligand, buffer and surfactant solutions have been investigated to obtain the best sublation efficiencies. Each solution flowed into the flotation cell through each polyethylene tube by the peristaltic pumps. The ternary complexes were floated and extracted into MIBK in a flotation cell of 2 L by bubbling a nitrogen gas. The absorbances of extracted analytes in MIBK were directly measured by graphite furnace-AAS. The concentrations of 1,10-phenanthroline and thiocyanate ion were 2.6 x 10-3 M and 2.3 x 10-2 M in the mixed solution, respectively. The pH of sample solution was adjusted to 5.0 with a buffer solution and 1%(m/v) sodium lauryl sulphate solution was added as a surfactant to support the effective flotation of the complexes. The N2 gas was bubbled at 30 mL/min for 90 minutes for 20 L of sample. Reproducible results of less than 10% RSD and recoveries of 80-120% could be obtained in real samples

AbstractAbstract
[en] The complexes [(L)2MnO2Mn(L)2]3+ where L = 2,2'-bipyridine or 1,10-phenanthroline, have been examined, in addition to the corresponding (IV, IV) complex of phenanthroline. The crystal structure of the mixed valence (III, IV) compound with L = 2,2'-bipyridine demonstrated that this complex has deeply trapped valences, corresponding to class II in the classification of Robin and Day since the bond lengths differ considerably about the manganese ions. We have examined the electronic spectrum of the (III, IV) complexes and observed broad bands in the near infrared which we have assigned to the mixed valence band expected for a class II system. No comparable band is observed for the phenanthroline (IV, IV) complex. Lowering the pH of (III, IV) dimer solutions reversibly cleaves the antiferromagnetically coupled (III, IV) dimers as determined by the increase in solution magnetic susceptibility; loss of the near infrared band occurs with dimer cleavage, although the remainder of the visible spectrum is substantially unaltered. Both absorbance and solution magnetic susceptibility changes with pH are reversible. The solvent dependence of the near infrared band is small but apparently opposite to that predicted by Hush's theory. However, the bandwidths agree well with those predicted from Hush's treatment (e.g., 0.53 μm-1 predicted, 0.46 μm-1 observed). A band at 688 cm-1 in the infrared spectrum of the bipyridyl (III, IV) dimer is shifted by isotopic substitution with 18O, and has been assigned to one of the stretching modes of the Mn2O2 bridge; analogous bands are found for the phenanthroline (III, IV) and -(IV, IV) complexes. Pertinent aspects of the electrochemistry are also discussed

AbstractAbstract
[en] A novel Er(III) complex with oxydiacetate and 1,10-phenanthroline was synthesized and its structure and luminescence properties were characterized. The complex of [Er(ODA)·(phen)·4H2O]+ crystallizes in the monoclinic space group P21/n with a = 12.216(4) A, b = 16.680(2) A, c = 12.627(3) A, β = 108.30(2) .deg. , V = 2442.7(11) A3, Z = 4 and ρ = 1.841 g/cm3. When the complex is excited at the He-Cd 325-nm line, it produces two broad bands spanning the regions 350-650 nm and 1200-1650 nm. The emission band of the complex is characterized by a series of spectral dips in the visible emission profile. The complex exhibits sensitized near-IR emission via two kinds of energy transfers from phen to Er(III): nonradiative and radiative energy transfers

AbstractAbstract
[en] A study has been made of uranyl chloride complexes with heterocyclic amines of the general formula [UO2Cl4][AmH]2, where Am is pyridine, dipyridine, picolin, chinolin, phenanthroline. Thermal stability has been studied. The main features of the thermolysis are: elimination of the amine hydrochloride in the temperature range from 303 to 345 deg C; complete decomposition of the compounds in the narrow temperature range from 303 to 427 deg C; UO2 is the final product of the decomposition. It has been found on the basis of comparison of melting point ranges and temperature ranges of complete decomposition of the complexes that their stability decreases in the following series: pyridine > dipyridine > chinolin > phenathroline
