На примере модельной смеси неорганических анионов показано, что использование on-line концентрирования позволяет снизить пределы обнаружения аналитов в 490 - 930 раз. Установлено, что количественного извлечения йодид-иона удалось достичь при пробоподготовке высушенного образца морской капусты. Предложенный способ определения йодида характеризуется простотой, экспрессностью (время анализа составляет 10 мин, пробоподготовки - 16 мин). Сходимость результатов измерений - 5,2 %, внутрилабораторная прецизионность - 7,3 %, предел обнаружения - 110 мкг/кг высушенного образца (9,2 мкг/кг в пересчете на свежую морскую капусту).</p></abstract><trans-abstract xml:lang="en"><p>A method of quantitative determination of iodide-ion in laminaria by «water-in-oil» microemulsion electrokinetic chromatography coupled with preliminary sample preconcentration procedure has been developed. On-line preconcentration technique, i.e., field-enhanced sample injection provided up to a 930-fold improvement in the detection sensitivity of inorganic anions. It was found that the full extraction of iodide could be achieved by the sample pretreatment of laminaria in a dry form. The developed method is rapid and easy to use (the time of analysis and sample pretreatment is 10 min and 16 min, respectively). Intra-day precision is found to be 5.2%, inter-day precision - 7.3%. The detection limit is 110 μg/kg of laminaria in a dry form (9.2 μg/kg in equivalent of fresh laminaria).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>йодид</kwd><kwd>микроэмульсия типа «вода в масле»</kwd><kwd>микроэмульсионная электрокинетическая хроматография</kwd><kwd>электростэкинг</kwd><kwd>он-лайн концентрирование</kwd><kwd>iodide</kwd><kwd>«water-in-oil» microemulsion</kwd><kwd>microemulsion electrokinetic chromatography</kwd><kwd>field-enhanced sample injection</kwd><kwd>on-line preconcentration</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">Cao J., Dun W.-L.
