Description
Изобретение относитс к аналитической химии и может быть использовано дл анализа ванади в нефт х и нефтепродуктах.This invention relates to analytical chemistry and can be used to analyze vanadium in petroleum and petroleum products.
Целью изобретени вл етс повышение селективности и экспрессности анализа ванади в нефт х и нефтепродуктах .The aim of the invention is to increase the selectivity and rapidity of analysis of vanadium in petroleum and petroleum products.
Предлагаемый способ иллюстрируетс чертежом.The proposed method is illustrated in the drawing.
Способ анализа ванадир в нефт х и нефтепродуктах реализуетс следующим образом.The method of analysis of vanadir in petroleum and petroleum products is implemented as follows.
Навеску нефти раствор ют в толуоле . Полученный раствор подают в анодную камеру 1 электролизера с нерастворимыми графитовыми электродами 2, которые отделены от рабочих камер защитными мембранами 3. Катодна ка- мера 4 непроточна и заполнена 0,1 М раствором хлористого аммони (рН 7-9) куда опущены измерительный графитовый 5 и вспомогательный каломельный 6 электроды. Анодна и катодна камеры разделены инертней разделительной мембраной 7. Электрохимическую экстракцию ванади провод т на переменном асимметричном токе частотой 47,5-1 Гц с соотношением iq/iy (1-9):10, который подаетс от источника 8. После того как весь раствор нефти пропущен через электролизер отключают источник переменного асимметричного тока и через 1-2 мин провод т пол рографическое определение ванади в объеме катодной камеры 4. Дл этого включают пол рогра 9 и провод т электронакопление определ емого элемента на поверхности графитового электрода 2 в течени 10 мин приCfэ -1,4 В при непрер зной продувке раствора инертным газ t - гелием через штуцер 10. Затем помощью крана перекрывают лото инертного газа и спуст 1-2 мин рем успокоени раствора) прово г электрорастворение осадка ванз с поверхности графитового электр j 5 с реа СОA portion of the oil is dissolved in toluene. The resulting solution is fed to the anode chamber 1 of the electrolytic cell with insoluble graphite electrodes 2, which are separated from the working chambers by protective membranes 3. The cathode chamber 4 is not flowing and filled with a 0.1 M ammonium chloride solution (pH 7-9) where the graphite measuring 5 is lowered and auxiliary calomel 6 electrodes. The anodic and cathodic chambers are separated by an inert separator membrane 7. Vanadium electrochemical extraction is carried out at an alternating asymmetric current of 47.5-1 Hz with iq / iy ratio (1-9): 10, which is supplied from source 8. After the entire solution oil is passed through the electrolyzer and the source of alternating asymmetric current is disconnected and after 1-2 minutes a polarographic determination of vanadium is carried out in the volume of the cathode chamber 4. To do this, turn on the floor 9 and electron accumulation of the element being detected on the surface of graphite electrode 2 for 10 minutes at Cfe -1.4 V with continuous solution of the solution with an inert gas t - helium through the nozzle 10. Then, using a crane, block the inert gas lotto and after 1-2 minutes a solution reassurance solution) wire dissolves surface graphite electr j 5 with pea CO
