TRLIF может быть применен для анализа биологических проб. Соединения Pu, Np, и U не создают прямой люминесценции в растворах, но при воздействии лазерного излучения, они могут индуцировать хемилюминесценцию хемилюминогена (люминал в наших экспериментах).Присутствие задержки во времени между импульсом лазерного излучения и импульсом хемилюминесценции позволяет использовать разрешение по времени (TR) для определения хемилюминесценции (TRLIC). Используя хемилюминесценции в растворах, мы обнаружили метод регистрации плутония, урана и других элементов в растворах с высокой чувствительностью возбуждения плутония и урана импульсным лазером с регулируемой длиной волн. Многоэтапная схема возбуждения хемилюминесценции делает этот процесс не только высокочувствительным, но также высокоселективным при определении соединений.</p></abstract><trans-abstract xml:lang="en"><p>At present the most efficient methods of detection of actinides and lanthanides in solutions are methods based on registration of actinides with time resolution, time-resolved laser induced fluorescence (TRLIF) spectroscopy. TRLIF may be applied for biological samples analysis. Pu, Np, and some U compounds do not produce direct luminescence in solutions, but when excited by laser radiation, they can induce chemiluminescence of chemiluminogen (luminol in our experiments). The presence of a time delay between the pulse of laser radiation and the chemiluminescence pulse allows using time resolution (TR) procedure for detection of chemiluminescence (TRLIC). Using chemiluminescence of solutions, we found an approach to registration of plutonium, uranium, and other elements in solutions with a high sensitivity in excitation of plutonium and uranium with a pulse laser with tunable wavelength. A multi-step scheme of chemiluminescence excitation makes this procedure not only highly sensitive but also highly selective method of detection of substances.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">I.N.
