| dc.description.abstract | Для термостабилизации соединений легколетучих некарбидообразующих элементов при электротермическом атомно-абсорбционном определении в объектах сложного состава предложен новый химический модификатор – комплекс палладия(II) с тиомочевиной. На модельных системах исследованы высокотемпературные процессы превращения модификатора в ходе атомизации и установлены факторы, определяющие его эффективность | en_US |
| dc.description.sponsorship | The new chemical modifier palladium(II) complex with thiourea for temperature stabilization of volatile non carbide-forming elements compounds in electrothermal atomic absorption determination in complex composition objects was proposed. High-temperature processes of proposed modifier transformation during atomization and the factors determining its effectiveness were studied on model systems. The proposed modifier has a low own nonselective absorption, provides a low-temperature thermal stabilization of analytes compounds during the early pyrolysis stages by step decomposition of the complex and recovery of palladium(II) to the metal, shifts the analytical signal of analytes to a higher temperatures range, leads to increasing of the maximum pyrolysisn temperature for cadmium and antimony on 600 and 350 ° C, respectively. The high efficiency of the proposed modifier while eliminating the depressing effect of 0.1 M nitric acid and hydrochloric acid solutions, sodium chloride and sulfate in ETAAS determination of cadmium and antimony in industrial solutions has been shown. | en_US |
