Description

Известно несколько способов определени  углерода в сере, например , способ экстрагировани  с весовым или калориметрическим определением органического вещества, способ сухого и мокрого сжигани  и др.There are several methods for determining carbon in sulfur, for example, an extraction method with a weight or calorimetric determination of organic matter, a dry and wet combustion method, etc.

Недостатками существующих методов  вл етс  их мала  чувствительность и точность, а также длительность определени .The disadvantages of the existing methods are their small sensitivity and accuracy, as well as the duration of the determination.

Также известно поглощение окислов серы силикатными поглотител ми .The absorption of sulfur oxides by silicate scavengers is also known.

Предлагаетс  способ определени  углерода в комовой сере сжиганием ее в токе кислорода и последующем поглощении окислов серы силикатным поглотителем и замера в эвдиометре объема газовой смеси C02-I-02, а затем вторичного замера объема кислорода после поглощени  двуокиси углерода раствором едкого кали.A method is proposed for determining carbon in lump sulfur by burning it in a stream of oxygen and subsequent absorption of sulfur oxides by a silicate absorber and measuring the volume of the gas mixture C02-I-02 in the eudiometer, and then secondary measuring the volume of oxygen after absorbing carbon dioxide with a solution of potassium hydroxide.

Выполнение метода сводитс  к следующему.The execution of the method is as follows.

При сжигании навески комовой серы в токе кислорода при температуре 800° весь углерод независимо от его состо ни  сгорает до СО2, а сера-до ее окислов, которые поглощаютс  силикатом (бари , кальци ) и хромовым ангидридом, а углекислый газ в смеси с избытком кислорода поступает в газоанализатор типа ГОУ-1, в эвдиометре которого производ т измерение объема полученной газовой смеси (СО2-)+О2 ). Затем смесь прокачивают уравнительной грушей в поглотительный сосуд газоанализатора с раствором едкого кали, где происходит поглощение углекислого газа. Разность между первым и вторым отсчетами по щкале эвдиометра соответствует количеству поглощенной углекислоты.When a lumpy sulfur sample is burned in a stream of oxygen at 800 ° C, all carbon, regardless of its state, burns to CO2, and sulfur to its oxides, which are absorbed by silicate (barium, calcium) and chromic anhydride, and carbon dioxide is mixed with an excess of oxygen. enters the gas analyzer of the type GOU-1, in the eudiometer of which the volume of the produced gas mixture (CO2 -) + O2 is measured. The mixture is then pumped with an equalizing pear into the absorption vessel of the gas analyzer with a solution of caustic potash, where carbon dioxide absorption takes place. The difference between the first and second readings on the scale of the eudiometer corresponds to the amount of carbon dioxide absorbed.

Делени  шкалы эвдиометра соответствуют процентному содержанию углерода в навеске вещества в 1 г.The dividing scale of the eudiometer corresponds to the percentage of carbon in the sample of a substance in 1 g.

Применение силикатных поглотителей в анализе комовой серы в сочетании с газоанализатором дл  определени  углерода не известно.The use of silicate absorbers in the analysis of lump sulfur in combination with a gas analyzer to determine carbon is not known.

№ 142800- 2 Метод отличаетс  высокой точностью определени  и дает возможность определ ть дес тые и сотые доли процента углерода ,9%-ной комовой сере (относительна  ошибка ±6-7%) и относительной быстротой определени  (15--20 мин).No. 142800-2. The method is distinguished by high accuracy of determination and makes it possible to determine the tenth and hundredth fractions of carbon percent, 9% lump sulfur (relative error ± 6-7%) and relative speed of determination (15--20 min).

.Предлагаемый способ внедрен в практику аналитической лаборатории ГИГХСа-н химической лаборатории Роздальского химкомбината .. The proposed method has been introduced into the practice of the analytical laboratory of the GIGHSa-n chemical laboratory of the Rozdalsky chemical plant.

Предмет изобретени Subject invention

Способ определени  углерода в комовой сере после ее сожжени  в токе кислорода, отличающийс  тем, что, с целью ускорени  и увеличени  чувствительности определени , количество углерода определ ют по разности объемов углекислого газа с кислородом и одного кислорода, поглотив предварительно окислы серы силикатными поглотител ми .The method for determining carbon in lump sulfur after it is burned in a stream of oxygen, characterized in that, in order to accelerate and increase the detection sensitivity, the amount of carbon is determined from the difference in volumes of carbon dioxide with oxygen and oxygen alone, having previously absorbed sulfur oxides by silicate absorbers.
