Description
Изобретеше относитс к -твшологйж изготовлени электрода срав ЕенЕ дл потенщометрического титровани в оксидиметрий в агрессивных средах, в частности в среда плавиковокислых растворов.The invention relates to the manufacture of an electrode comparing with EE E for potentiometric titration in oximetry in corrosive media, in particular in the environment of hydrofluoric acid solutions.
Известен способ изготовлени электрода сравнени дл аотенциометрического титровани в ОКСИДЕметрии из кислородных ванадиевых бронз типа MeV50i5 . и где Me- К. Na, Си i Ме Са, Cd njrew прессовани мелкокристаллического порошка бронзы под небольжим давлением в отрезке стекл нной трубки.A known method of making a reference electrode for aotentiometric titration in OXYDEMETRY from oxygen vanadium bronzes of the type MeV50i5. and where Me is K. Na, Cu i Me Ca, Cd njrew pressing a fine-crystalline bronze powder under low pressure in a piece of glass tube.
Однако известный.способ отличаетс недостаточной механической прочностью и неустойчивостью электрода в агрессивных-средах плавиковокислых растворов.However, the known method is characterized by insufficient mechanical strength and instability of the electrode in aggressive fluids.
По предшагаемому способу изготовление электрода ведут путем прессовани мелкокристаллического порошка кислородных ванадиевых idDOHS указанного типа, предвари1тельно смешанного с .эпоксидно смо лой и отвеодателемt..вз тыми в количестве 1-2% от веса порошка, под давлением 150-250 кг/см2. Затем 5 электрод выдерживают при комнатной температуре в течерше 1-2 суток., Получаемый электрод вл етс беспористым, имеет повышенную механическую прочность и может ис- In accordance with the preceding method, the electrode is fabricated by pressing a fine-crystalline oxygen powder vanadium idDOHS of the specified type, which is preliminarily mixed with an epoxy resin and an extractor .. taken in an amount of 1-2% by weight of the powder, under a pressure of 150-250 kg / cm2. Then, the 5 electrode is kept at room temperature for 1–2 days. The resulting electrode is nonporous, has an increased mechanical strength, and can be used
пользоватьс в агрессивной среде плавиковокислых растворов пои повышенных температурах (30-7000), Электрод обладает устойчивым потенщалом и имеет хороший сигнал вuse in an aggressive environment of hydrofluoric acid solutions and high temperatures (30-7000), the Electrode has a stable potential and has a good signal in
5 точке эквивалентности.5 equivalence point.
