(54) Selektivní náplň pro absorpci hologenfl, kysličníků siry a fluoru při elementární analýze organických látek(54) Selective charge for absorption of hologenfl, sulfur oxides and fluorine in elemental analysis of organic compounds
Vynález ee týká selektivní náplně pro absorpci halogenů, kysličníků siry a popřípadě fluoru při elementární analýze organických látek.The invention relates to a selective charge for the absorption of halogens, sulfur oxides and optionally fluorine in the elemental analysis of organic matter.
Při elementární analýzo uhlíku, vodíku a dueiku je nutno po epálenl vzorku eliminovat ze eměei plynů elementy, ruělcl stanovení kysličníku uhličitého, vody a dusíku. Osou to především halogeny a sira. K tomuto účelu ee používá kovového stříbra, které při 550 °C až 850 °C v oxidační atmosféře kvantitativně absorbuje halogeny a kysličníky airy. Stříbrné vata, popřípadě jemně granulované stříbro ao spéká a má malý povrch, takže průtoková rychlost plynů touto vrstvou je značně omezena, jinak nedochází ke kvantitativní absorpci rušících elementů. Podstatně výhodnější jsou eměei jemně rozptýleného stříbra nebo kysličníku stříbrného e některými anorganickými kysličníky, jako kysličníkem kobaltnatokobeltltým, menganičitýa, které avými eorpčnlmi vlastnostmi půaobi retenci rušících elementů, a tlm přispívají k jejich intimnímu etyku ea stříbrem. Nevýhodou použiti zmíněných kysličníků jsou omezené maximální teplotní hranice jejich použiti, u kysličníku mangenlčltáho 550 °C, u kysličníku kobaltnatokobeltitého 800 °C.In the elemental analysis of carbon, hydrogen and due dilution, the elements, carbon dioxide, water and nitrogen have to be eliminated from the gas mixture after epalenation of the sample. They are mainly halogens and sulfur. For this purpose, ee uses silver metal which quantitatively absorbs halogens and airy oxides at 550 ° C to 850 ° C in an oxidizing atmosphere. Silver wool or fine granulated silver o sinters and has a small surface area, so that the gas flow rate through this layer is considerably limited, otherwise there is no quantitative absorption of the interfering elements. Substantially more preferred are the finely divided silver or silver oxide emulsions with some inorganic oxides such as cobalt tetrachloride, manganese dioxide, which, by virtue of their absorbent properties, contribute to the retention of the interfering elements and contribute to their intimate ethylene and silver. A disadvantage of the use of said oxides is the limited maximum temperature limits of their use, for manganese oxide 550 ° C, for cobalt oxide-cobalt oxide 800 ° C.
Tyto dosavadní nevýhody odstraňuje selektivní náplň pro absorpci halogenů a kysličníků siry při elementární analýze organických látek podle uvedeného vynálezu, jejíž podstatou je, že eeatává ze eměei 5 až 80 % stříbra a 20 až 95 % kysličníku cíničitáho.These prior disadvantages are overcome by the selective charge for the absorption of halogens and sulfur oxides in the elemental analysis of the organic compounds of the present invention, which consists in emitting 5 to 80% of silver and 20 to 95% of tin dioxide.
Oalěl výhodné provedeni jo, že se ke eměei stříbra a kysličníku cíničitáho přidáAnother preferred embodiment is that silver and tin oxide are added to the mixture
200 OOS kysličník hořečnátý, který působí jako abeorber pro fluor a jeho sloučeniny.200 OOS magnesium oxide, which acts as an abeorber for fluorine and its compounds.
Hlavni přednosti této selektivní náplně je, že enáčl teploty do 9SO °C a vykazuje vynikající absorpční efekt vůči halogenem a kysličníkům alry, a současně pčaobl jako spalovací katalyzátor.The main advantage of this selective charge is that it has enriched temperatures up to 90 ° C and exhibits an excellent absorption effect against halogen and alrylic oxides, while at the same time acting as a combustion catalyst.
Přiklad přípravy uvedené náplně:Example of preparation of the mentioned filling:
k práškovému kysličníku cinlčlténu aa přidá za chladu nasycený roztok dusičnanu stříbrného do vytvořeni kačovlté konzistence a po promícháni ae auSi při 120 °C, a pak žlhé několik hodin při 900 °C až do úplného odstraněni kysličníků dusíku. Získané čadě hmota aa drti a frakcionuje na vhodné zrněni, např. 0,5 až 1,0 mm.to a powdered cinnamon oxide aa add a saturated solution of silver nitrate in the cold until a ducky consistency is obtained and after stirring at a temperature of 120 ° C and then yellow for several hours at 900 ° C until the nitrogen oxides are completely removed. The obtained chow mass a and grits and fractionates on a suitable grain, e.g. 0.5 to 1.0 mm.
Oeatliže mé náplň absorbovat také fluor, přidá aa ke kysličníku clnlčltému ještě kysličník hořečnetý, např. v poměru 3:1, aměa ae promíchá, přidá aa za ohladu nasycený roztok dusičnanu stříbrného do vzniku kačovlté konzistence, přičemž probíhá reakce a aměa ae čokoládově zbarvi. Pak ae eučl při 120 °C a nakonec žlhé při 900 °C do úplného odstraněni kyallčnikú dusíku. Selektivní náplň je vhodné pro použiti v automatizovaných elementárních analyzátorech.While my cartridge also absorbs fluorine, aa adds magnesium oxide, e.g., in a 3: 1 ratio, and mix and mix, and then add a saturated solution of silver nitrate to a ducky consistency while the reaction proceeds and a chocolate color. It was then run at 120 ° C and finally yellow at 900 ° C until the nitrogen oxides were completely removed. The selective cartridge is suitable for use in automated elementary analyzers.
