In the atomic absorption spectrophotometry using an air-acetylene flame, both titanium and niobium existing as peroxo-complex compounds (presumably peroxo-) in nickel-base alloy sample solution seriously interfere with the determination of copper, manganese, and cobalt. Obtained absorbance readings for these elements show random values. The following two dissolution treatments have been examined: 0.5 g portions of the sample are dissolved in (1) HNO3 (5 ml) +HCl (5 ml) +HF (1 ml), (2) 3N-H2SO4 (25 ml) +HCl (10 ml) +H2O2 (10 ml), and the solutions are diluted exactly to 100 ml with water. In the former, no interference effect is observed. In the latter, irregular absorbance readings are obtained for copper, manganese, and cobalt. No interference effect is observed, however, when a nitrous oxide-acetylene flame is used. The mechanism of the interference effects has been investigated by using an especially prepared twin-nebulizer. From the result, it is concluded that the origin of the interference effects can be attributed to the vaporization behavior of wet aerosols. Probably, these aerosols make refractory compounds in the air-acetylene flame and the compounds occlude copper, manganese, and cobalt and the incomplete dissociation of these compounds traversing the flame zone causes the irregular absorbance readings.

A direct, quantitative analytical technique for the analysis of gadolinium, dysprosium, europium and samarium in aluminum oxide using the X-ray-excited optical fluorescence spectra is described. Rare earth elements were coprecipitated with host aluminum from acid solution as aluminum hydroxide. Precipitated hydroxide was dried after centrifugal separation and then heated in a muffle furnace at 1000°C for 2 hours. These oxides were then heated at 1450°C in an electric resistance furnace for 60 seconds. Such an impulsive heating followed by quenching, described above, prominently enhances the luminescent intensities of rare earth elements. It was shown by the X-ray diffraction method that the crystal of Al2O3 were transformed from γr-type oxide to the stable α-type oxide during the above heat treatment. Concentrations of gadolinium, dysprosium, samarium, europium have been determined by this method with detection limits ranging from 0.05 to 1.0ppm. Reproducibility was found to be 5-10%.The enhancement and suppression effect due to iron, silicon and copper were investigated and discussed.

A high voltage a. c. arc source unit of usual type was constructed in order to develop the spectrochemical methods of trace elements in iron and steel. This arc supply consists of a power transformer having a 220 volt primary and two 2200 volt secondaries, each capable of supplying 2.2 amperes. A switching system allows the secondaries to be hooked inseues or parallel, so that two voltage ranges are available; 2200 and 4400. Seventy heater type coils wounded by 0.5 mm “Advance” wire are used as a ballast resistors in the secondaries and permit one to control the current from ampere to ampere at 4400 volt range and from to ampere at 2200 volt range. The arc stand in locked into safety cage and the door of this cage act, as a switch preventing the current to flow into trasformer primary when this door is opening.

High voltage a. c. arc source, which is secondarily shunted by large capacitor, is used as a excitation source. Powdered sample is deposited on_a massive copper bar moistened with collodion (diluted with Amyl-acetate), dried at 110°C, and installed as the lower electrode with a cone-shaped upper electrode. As the discharge proceeds to burn, the lower electrode is moved towards the direction perpendicular to the optical axis of the Zeiss Qu-24 spectrograph, exposing fresh sample surfaces for discharge. Spectral lines are clearly seen under these conditions down to 0.01% for sulfur, selenium, chlorine, bromine, and iodine, but such a high sensitivity can not be obtained for fluorine.

Novel interface-selective second-order (χ (2) ) and fourth-order (χ (4) ) nonlinear spectroscopic techniques were developed to study liquid interfaces. χ (2) electronic sum frequency generation (ESFG) spectroscopy provides interfacial electronic spectra with an unprecedented high signaltonoise ratio in a short measurement time, whereas frequencydomain χ (4) Raman spectroscopy realized observation of vibrational spectra of solute molecules adsorbed at interfaces for the whole fingerprint region. Because these new evenorder electronic and vibrational nonlinear spectroscopies utilize only visible and nearinfrared laser pulses, they are applicable to the study of a variety of “buried” interfaces.

We developed a near-field scanning optical microscope (NSOM) giving infrared spectra in an area smaller than the diffraction limit of the infrared light. The developed NSOM features a probe which is equipped with a slit aperture to improve the efficiency in collecting the near-field light. The illumination light is generated with a Michelson interferometer as an interference light and the transmission spectrum of sample at the local position is given through the slit of probe. The experimental results with a test chart and a two-layered film show that the spatial resolution of the IR-NSOM developed depends only on the slit width and not on the wavelength of the illumination light. The spatial resolution of the microscope has been numerically analyzed with finite-difference time-domain (FD-TD) method.
