Description

ческих соединени х с различным соотношением талли  и галогена. Способ позвол ет одновременно с таллием определ ть в анализируемой пробе содержание галогеновi в виде их хлоридов известными методами. Дл  низкотемпературной плазменной минерализации используют аппарат УВЧ-66 (мощность 20-70 Вт) с параллельно включенным резонансным контуром. Разложение ведут в кварцевом реакторе, расположенном внутри соленоида.comic compounds with different thallium and halogen ratios. The method allows simultaneously with thallium to determine in the analyzed sample the content of halogens in the form of their chlorides by known methods. For low-temperature plasma mineralization, a UHF-66 apparatus (power 20–70 W) with a parallel-connected resonant circuit is used. The decomposition is carried out in a quartz reactor located inside the solenoid.

Пример. Дл  определени  талли  навеску исследуемого соединени  тщательно смешивают с тонкоизмельченным нитратом аммони  высокой чистоты и помещают в кварцевый реактор. Систему в куумируют до давлени  5 мм рт.ст., подают аммиак со скоростью 7 мл/мин и при мощности 40 Вт включают разр д. Разложение провод т 8 мин. Образующийс  в результате разложени  оксид талли  (111) определ ют гравиметрически. При разложении 1,12 мг вещества состава a-ic SoNijOs-Ti, содержащего 34,39% талли  найдено 34,36% талли . Образовавшийс  на стенкс1Х реактора хлорид аммони  смывают и определ ют хлоридион титрованием раствором нитрата ртути (11).Example. To determine the thalli, the weighed compound under test is thoroughly mixed with finely divided ammonium nitrate of high purity and placed in a quartz reactor. The system is quamed to a pressure of 5 mm Hg, ammonia is fed at a rate of 7 ml / min and the discharge is turned on at a power of 40 W. Decomposition is carried out for 8 minutes. The resulting decomposition of the thallium oxide (111) is determined gravimetrically. With the decomposition of 1.12 mg of a-ic SoNijOs-Ti compound containing 34.39% of thallium, 34.36% of thallium was found. The ammonium chloride formed on the stencil1X of the reactor is washed off and the chloride determined by titration with a solution of mercury nitrate (11).

Таким образом, по сравнению с известными предлагаемый способ позвол ет повысить точность определени  талли  и проводить одновременное определени  талли  и галогенов г - галогенсодержащих органических соединени х различного состава.Thus, in comparison with the known, the proposed method allows to increase the accuracy of thallium determination and to conduct simultaneous determination of thallium and halogens of g-halogen-containing organic compounds of different composition.
