A novel dispersive liquid-liquid semi-microextraction (DLLsME) procedure for copper(II) preconcentration is proposed. The system containing copper(II) and 6,7-dihydroxy-2,4-diphenylbenzopyrylium chloride (DHDPhB), after addition a mixture of chloroform and methanol becomes cloudy and the formation of the organic phase was observed immediately. The optimal conditions of DLLsME were found to be: pH 5, absorption band maximum was 570 nm, 1 cm3 of 1 × 10–3 mol/dm3 of DHDPhB, and mixed extractant containing 1 cm3 of chloroform and 1 cm3 of methanol. Under optimal conditions, the calibration plot was linear in the range of copper(II) concentration 4.32–65 μg/dm3 and the limit of detection was 1.29 μg/dm3. The rocks and tap water samples were successfully analyzed according to the suggested procedure with RSD no more than 4.9%.

Oxygen impurity in Germanium single crystals has been characterized using Fourier transformed infrared spectrometry. The crystals were grown by Czochralski method in an argon atmosphere. The oxygen concentration in crystals was determined on optical density from the absorption band at 843 cm−1. It was established that oxygen dissolved concentration in Germanium is variable from 0,2·1016 to 1,3·1016 сm−3. The oxygen band maximum shifts toward 856 cm−1 when its concentration increases under the influence of annealing in the oxygen containing atmosphere with ≤ 10−3 Па.
