Inductively coupled plasma atomic emission spectrometry (ICP-AES) and flame spectrometry are used to establish the stoichiometric composition of Li6Gd(BO3)3, Li5.4Na0.6Gd(BO3)3, LaB3O6, and SrB4O7 single crystals, including cerium-doped crystals. It

A method has been developed for the preparation of homogeneous moisture-resistant glasses with the composition Li2O-B2O3-P2O5-CaF2 : Ce3+-Gd3+. Energy transfer from Gd3+ to Ce3+ was noted in a study of the radioluminescence spectra of these samples u

A rapid, sensitive, and highly selective test based on the reaction of copper(I) with thio-Michler’s ketone was developed for the detection and semiquantitative determination of 0.001–2 mg/L copper in natural and potable waters using preconcentra

We propose a method for quantitatively taking into account nonselective absorption for systems in which the vapor phase contains a single molecular form: sodium and potassium chlorides and iodides. We identified the absorption bands using modern quan

It was shown that low-temperature directed crystallization of natural water can be used for separating chromium(III) and chromium(VI). At a moderate crystallization rate (6–10 mm/h), the final part of the ingot (concentrate) is a suspension contain

The regime of atomization of Si in the presence of Fe-subgroup metals was investigated with the use of a “Saturn” spectrophotometer and a “Graphit-2” electrothermic atomizer. The optimal operating parameters of the atomizer have been determin

A method of scanning photodielectric spectroscopy of crystals has been suggested. It is based on the measurements of small increments of the real Δe′ and imaginary Δe″ parts of effective dielectric permittivity at a smooth variation of the phot

By taking as an example the obtaining of the spectra of the gas phase over alkali metal iodides and calcium fluoride, we show the possibility of eliminating systematic errors of atomic absorption analysis which are due to nonselective absorption of l
