Изучено влияние природы, объема диспергатора и экстрагента, добавления соли и времени проведения экстракции на эффективность извлечения аналитов. Диапазон определяемых концентраций составляет 0,005 - 0,05 мг/л. Пределы обнаружения ( S/ N = 3) керосинов РГ-1 и Т-1 - 0,0015 и 0,0022 мг/л соответственно. Сходимость результатов измерений для указанного выше диапазона изменяется от 16 до 9 % ( n = 3), внутрилабораторная прецизионность - от 20 до 12 % ( n = 5).</p></abstract><trans-abstract xml:lang="en"><p>A sensitive technique of rocket kerosene determination in water comprising dispersive liquid-liquid microextraction of analytes and their subsequent separation and determination by gas chromatography-mass spectrometry in the mode of chromatogram registration for the selected ions ( m/ z: 67, 81, 85, 95, 136, 137, 174, 183 and 193) is developed. The effect of the nature, amount of extractant and dispersant agents, salt adding and time of extraction on the efficiency of analyte extraction is studied. The detectable concentrations range within 0.005 - 0.05 mg/liter. The detection limits ( S/ N = 3) for kerosene RG-1 and T-1 are 0.0015 and 0.0022 mg/liter respectively. Intra-day and inter-day precision of the results of measurements for the studied concentration ranges from 16 to 9% ( n = 3), and from 20 to 12% ( n = 5), respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ракетные керосины</kwd><kwd>хромато-масс-спектрометрия</kwd><kwd>газовая хроматография</kwd><kwd>жидкостно-жидкостная микроэкстракция</kwd><kwd>rocket kerosene</kwd><kwd>gas chromatography</kwd><kwd>mass spectrometry</kwd><kwd>extraction</kwd><kwd>dispersive liquid-liquid extraction</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гигиенические нормативы ГН 2.1.5.1315-03.
