(54) СПОСОБ ОПРЕДЕЛЕНИЯ НИКОТИНСУЛЬФАТА(54) METHOD FOR DETERMINING NICOTINESULFATE
1one
Изобретение относитс к аналитической химии пестицидов, а именно к способам количественного определени никотинсульфата в воде, воздухе и биоматериала на санитарно-эпидемических станци х, отделах токсикологии , агрохимических лаборатори х, станци х защиты растений.The invention relates to the analytical chemistry of pesticides, in particular, to methods for the quantitative determination of nicotine sulfate in water, air and biomaterial at sanitary-epidemiological stations, toxicology departments, agrochemical laboratories, and plants for the protection of plants.
Известен колориметрический метод определени никотинсульфата в воздухе, основанный на реакции Кенига путем перевода никотина в окрашенное соединение с помощью бромциана и а-нафтиламина и измерении оптической плотности образовавшегос красного раствора 1.A colorimetric method for determining nicotine sulfate in air is known, based on the Koenig reaction by transferring nicotine to a colored compound using cyanogen bromine and α-naphthylamine and measuring the optical density of the resulting red solution 1.
Недостаток этого метода - необходимость применени высокотоксичных реактивов .The disadvantage of this method is the need to use highly toxic reagents.
Наиболее близким по технической суш,ности и достигаемым результатам к изобретению вл етс способ определени никотинсульфата путем обработки раствора анализируемого вещества красителем - бромфеноловым синим в щелочной среде, экстракции полученного окрашенного соединени растворителем с последующим фотометрированием экстракта 2.The closest technical sushi-ing and achievable results of the invention is a method for determining nicotine sulfate by treating an analyte solution with a dye bromophenol blue in an alkaline medium, extracting the resulting colored compound with a solvent, and then photometricizing the extract 2.
Недостаток данного способа состоит в его относительно невысокой чувствительности (10 м).The disadvantage of this method is its relatively low sensitivity (10 m).
Цель изобретени - повышение чувствительности способа.The purpose of the invention is to increase the sensitivity of the method.
5Поставленна цель достигаетс тем, что5 The goal is achieved by the fact that
согласно способу определени никотинсульфата путем обработки раствора анализируемого вещества красителем - бромфеноловым синим в щелочной среде, экст ,„ .ракции полученного окрашенного соединени растворителем с последующим фотометрированием экстракта, в качестве красител используют антраценовый синий и обработку ведут в кислой среде.According to the method for determining nicotine sulfate by treating the analyte solution with a bromophenol blue dye in an alkaline medium, ext, extracting the resulting colored compound with a solvent followed by photometry of the extract, anthracene blue is used as a dye and the treatment is carried out in an acidic medium.
Способ отличаетс быстротой и точностью. Относительное стандартное отклонение не превышает 1,5% чувствительность .The method is fast and accurate. The relative standard deviation does not exceed 1.5% sensitivity.
Пример. Навеску никотийсульфата, содержащую 0,21 мг (0,5-10 м), взвешенную с точностью ± 0,02 мг, раствор ют в воде, Example. A portion of nicotium sulfate containing 0.21 mg (0.5-10 m), weighed to an accuracy of ± 0.02 mg, is dissolved in water,
20 смешивают с 2-5 мл 0,001 М водного раствора антраценового синего и буферного раствора (рН 1,0) в делительной воронке. После добавлени 5 мл хлороформа воронку тщательно встр хивают в течение 5-1020 are mixed with 2-5 ml of a 0.001 M aqueous solution of anthracene blue and a buffer solution (pH 1.0) in a separatory funnel. After adding 5 ml of chloroform, the funnel is shaken well for 5-10
мин и отдел ют слой хлороформа. Оптическую плотность экстракта измер ют на колориметре КФО в кювете 1 см оранжевым светофильтром, раствор сравнени - вода. Содержание никотинсульфата наход т по калибровочному графику. Калибровочныйmin and the chloroform layer is separated. The optical density of the extract was measured on a KFO colorimeter in a 1 cm cuvette with an orange color filter, and the comparison solution was water. The nicotine sulphate content is determined according to a calibration graph. Calibration
