Description
Изобретение относитс к аналитической химии, а именно к способам определени силикатного модул жидкого стекла, и может быть использовано дл рутинного анализа жидких стекол.The invention relates to analytical chemistry, and specifically to methods for determining the silicate module of liquid glass, and can be used for routine analysis of liquid glass.
Целью изобретени вл етс ускорение анализа при сохранении точности .The aim of the invention is to accelerate the analysis while maintaining accuracy.
Пример. Навеску 2,0 г жидкого натриево-содового стекла помещают в пробирку объемом 25 мг и довод т дистиллированной водой до 20 мл при интенсивном взбалтывании. Ввод т пипеткой 10 капель водного раствора пинацианолхлорида с рН 9,2в Развитие окраски происходит за 13 с. Окрашенный раствор сравнивают по цвету с предварительно приготовленным набором растворовстандартов из жидких стекол с известным силикатным модулем, который определ ют весовым методом, и по совпадению цветов пробы и стандарта оценивают силикатный модуль определ емой пробы.Example. A weighed portion of 2.0 g of liquid sodium soda glass is placed in a 25 mg tube and brought to 20 ml with distilled water with vigorous stirring. Pipette 10 drops of an aqueous solution of pinacyanol chloride with a pH of 9.2 in. Color development occurs in 13 seconds. The colored solution is compared in color with a previously prepared set of standard liquid glass solutions with a known silicate module, which is determined by a gravimetric method, and the silicate module of the sample being determined is evaluated by matching the colors of the sample and the standard.
В табл. 1 представлены экспериментальные результаты зависимости времени развити окраски от рН индикатора.In tab. Figure 1 shows the experimental results of the dependence of the color development time on the indicator pH.
В табл.2 представлены экспериментальные результаты зависимости времени развити окраски от концентрации реагента.Table 2 presents the experimental results of the dependence of the color development time on the concentration of the reagent.
Как следует из представленных результатов , оптимальна концентраци раствора пинацианолхлорида (2,...,8)х х при рН 8-10. Предлагаемый способ позвол ет проводить экспресс-As follows from the presented results, the optimal concentration of pinacyanol chloride solution (2, ..., 8) x x at pH 8-10. The proposed method allows for express
