Изобретение относитс к аналитической химии и может быть использовано при определении органических примесей в воздухе,The invention relates to analytical chemistry and can be used in the determination of organic impurities in the air,
Цель изобретени - полнота отделени вод ных паров от органических примесей при их определении в воздухе .The purpose of the invention is the completeness of separation of water vapor from organic impurities during their determination in air.
Пример, Цеолит 1ЗХ измельча- ют и рассеивают, отбира фракцию 0,4-0,5 мм. К 38 г цеолита добавл ют 80 мл водного раствора, содержащего 27 г глицерина и 30 г гидроксида кали и дл равномерной пропитки оставл ют массу на 1 ч при комнатной температуре. Затем массу помещают в сушильный шкаф, который нагревают от комнатной температуры до 200 С. ПослExample, Zeolite 1ZH is crushed and scattered, selecting a fraction of 0.4-0.5 mm. 80 ml of an aqueous solution containing 27 g of glycerol and 30 g of potassium hydroxide are added to 38 g of zeolite and the mixture is left for 1 hour at room temperature for uniform impregnation. Then the mass is placed in a drying oven, which is heated from room temperature to 200 C. After
этого начинают перемешивание массы, 20 в ходе которого темпер.атуру снижают, Цри достижении шкаф закрывают, температуру снова повышают до 200°С, после чего массу периодически (через 30 мин) перемешивают. Операции на- 25 грева и перейешивани продолжают до тех пор, пока масса станет сыпучей, а розова окраска цеолита 13Х перейдет в темно-коричневую,This is done by mixing the mass, 20 during which the temperature is reduced, when reaching the closet, the temperature is raised again to 200 ° C, after which the mass is periodically (after 30 min) mixed. The heating and transfer operations continue until the mass becomes loose, and the pink color of the zeolite 13X turns into dark brown,
Поглотители помещают плотным ело- зо ем (60 мм) в стекл нные трубки с внутренним диаметром 2,,5 мм. Положение поглотителей -в трубке фиксируют двум тампонами из стекловолокна.The absorbers are placed in a dense (60 mm) dense glass tube with an internal diameter of 2, 5 mm. The position of the absorbers in the tube is fixed with two tampons of fiberglass.
Трубки с поглотител ми присоеди- og н ют к стекл нным сосудам с водой. Через эти системы просасывают паровоздушные смеси в количестве 0,8 дм , содержащие метанол, изобутанол, ацетон в концентраци х 100 мг/м и ани- 40 ЛИН - 10 мг/ м. По разности между подаваемь1м на поглотитель количеством вещества и найденным после него (фотометрическим методом) в прибореTubes with absorbers are attached to glass vessels with water. 0.8 dm vapor-air mixtures containing methanol, isobutanol, acetone in concentrations of 100 mg / m and ana- 40 LIN - 10 mg / m are sucked through these systems. According to the difference between the amount of substance supplied to the scavenger and the amount found after it ( photometric method) in the device
