Description
Высока токсичность карбоиила никел , наход щего все более широкое применение в промышленности, насто тельно требует создани необходимых методов и автоматических приборов дл определени содержани карбонила никел в воздухе.The high toxicity of carboiyl nickel, which is becoming more and more widely used in industry, requires the creation of the necessary methods and automatic instruments for determining the content of nickel carbonyl in the air.
Предлагаемый способ определени микроколичеств карбонила никел с использованием его в качестве восстановител заключаетс в том, что, с целью новышеии чувствительности определений, анализируемый возду.х пропускают через трубку с красной окисью ртутп, нагрето до 200°, с последуюндим определением ижвестными спектроаналитическими методами концентрации освобождающихс в резуЛ1зтат(реакции паров ртути с использованием ультрафиолетовых из,лучеицн.The proposed method for the determination of microquantities of nickel carbonyl using it as a reducing agent consists in the fact that, in order to improve the sensitivity of the determinations, the analyzed air is passed through a tube with red oxide, mercury heated to 200 °, followed by determination and known concentration spectroanalytic methods, the concentrations released Result (reaction of mercury vapor using ultraviolet radiation, luchitn.
С целью повышени точности определенн содержани окиси углерода , рекомендуетс анализируемый воздух раздел ть на два потока, один из которых направл ют непосредственно через трубку с нагретой окисью ртути, а другой параллельно проходит предварительно через сорбеит, окисл ющий карбонил никел по известиой реакции до получени СОз, после чего воздух направл ют через нагретую окись ртути и определ ют известным методом разность концентрации паров ртути в обоих потоках, пропорциональную содержанию карбонила никел в анализирземом воздухе.In order to improve the accuracy of the determined carbon monoxide content, it is recommended to separate the analyzed air into two streams, one of which is sent directly through a tube with heated mercury oxide, and the other passes parallel to the preliminary through sorbeite, an oxidizing nickel carbonyl through a lime reaction to produce CO2. after which the air is directed through heated mercury oxide and the difference in concentration of mercury vapors in both streams is determined by a known method, which is proportional to the content of nickel carbonyl in the ground air ear.
Описанный метод позвол ет определ ть до 10 .i/;xv/. карбонила никел . Некотора Р1еспецифичиость прин той реакции по стиошепию к окиси углерода может быть устраиена путем прпменени описанного выше дифференциального способа оироделенн . При -;том разноеть концентраций паров ртути, пропорциональную содержанию карбонила никел в анализируемом воздухе, измер ют соответствуюнанм прибором , поетроепным по дифференциальной схеме, например ИКРП-- 46.The described method allows to define up to 10 .i /; xv /. carbonyl nickel. Some of the specificity of the reaction to carbon monoxide can be improved by applying the differential method described above to irodelenn. At - the difference in mercury vapor concentrations, proportional to the content of nickel carbonyl in the analyzed air, is measured by the corresponding device, which is based on a differential scheme, for example, ICRP-46.
