“…It was corroborated by measuring the thickness directly using a micrometre, in which the CV values ranged from 5.6 to 22%. Taking into account that this feature is intrinsic to the garbage bag samples, this analytical drawback might be overcome by analysing the sample either by using the neutron activation analysis (NAA) [26,27] or after sample digestion and subsequent analysis by another spectrochemical technique, such as TXRF [28], AAS [4], ICP-MS [7] or even EDXRF [29,30]. It must be mentioned that a reactor facility is required for NAA analysis.…”

“…В случае концентрирования и разделения неорганических токсикантов часто прибегают к функционализации поверхности силикагеля ана-литическими группировками с донорными атомами, способными координировать металлы и образовы-вать устойчивые хелаты. Применение в химиче-ском анализе таких сорбционных материалов по-зволяет значительно улучшить метрологические характеристики [6,7] и уменьшить матричные по-мехи [8] при определении токсикантов в природ-ных образцах сложного состава. Особый интерес представляют сорбционные материалы на осно-ве силикагеля, позволяющие проводить не только предварительное концентрирование из природных и технологических водных образцов, но и выполнять разнообразное инструментальное детектирование (атомно-абсорбционной [9,10], атомно-эмиссион-ной спектроскопией с индуктивно связанной плаз-мой [11,12], спектрофотометрией [13]) таких норми-руемых высокотоксичных загрязнителей, как ртуть.…”

“…In 2010, Marguí et al . reviewed practical aspects related to the use of extractive and non‐extractive sample preparation of elements before their detection by XRF . However, the interest in preconcentration methods for XRF has increasingly turned towards the refinement of its modes for use in practical sample preparations.…”
