Description
Изобретение относитс к аналитической химии, в частности к способам количествен но го спектрофотометрического определени сурьмы в полимерах декоративно-отделочных материалах (ПДОМ), и может быть использовано при технологическом контроле этих материалов.The invention relates to analytical chemistry, in particular, to methods for the quantitative spectrophotometric determination of antimony in polymers of decorative finishing materials (PDOM), and can be used in the process control of these materials.
Целью изобретени вл етс повышение экспрессности и упрощение анализа.The aim of the invention is to increase the speed and simplify the analysis.
Способ осуществл етс следующим образом .The method is carried out as follows.
Навеску полимерного материала подвергают термической деструкции в течение 1 ч. Из зольного остатка, содержащего сурьму , готов т анализируемый раствор путемA portion of the polymer material is subjected to thermal decomposition for 1 hour. An analyte solution is prepared from an ash residue containing antimony.
растворени его в концентрированной сол ной кислоте с последующим разбавлением водой. Устанавливают рН анализируемого раствора 2,5, затем добавл ют карбоксил- диоксихроменол (6,7-диокси-2-фенил-4-кар- боксилбензопирилий хлорид) в количестве 3-4 мл концентрации и 1,5-2,0 мл цетилтриметиламмоний бромида концентрации на 50 мл исследуемого раствора , фотометрируют раствор при А 500-510 нм, содержание сурьмы определ ют по калибровочному графику.dissolving it in concentrated hydrochloric acid, followed by dilution with water. The pH of the analyzed solution is adjusted to 2.5, then carboxyl-dioxychromenol (6,7-dioxy-2-phenyl-4-carboxylbenzopyrylium chloride) is added in an amount of 3-4 ml of concentration and 1.5-2.0 ml of cetyltrimethylammonium bromide concentrations per 50 ml of the test solution; photometry the solution at А 500-510 nm; the content of antimony is determined according to the calibration graph.
Пример. Навеску полимерного материала в количестве 0,1 г подвергают термическому разложению при 500-550° в течение 1 ч. Зольный остаток раствор ют вExample. A portion of the polymer material in an amount of 0.1 g is subjected to thermal decomposition at 500–550 ° for 1 hour. The ash is dissolved in

According to the measured optical density, the amount of antimony in the sample is determined using the calibration curve.
Предел обнаружени сурьмы в полимерном декоративно-отделочном материале составл ет 1,10 %., Относительное стандартное отклонение результатов параллельных определений не превышает величину 0,02.The detection limit for antimony in a polymeric decorative finishing material is 1.10%. The relative standard deviation of the results of parallel determinations does not exceed a value of 0.02.
