泵行业铂族金属的重要化合物

卤化物:所有细碎粉末状的铂族金属在加热的情况下同氯反应，在一定的条件下生成挥发性的卤化物。铂族金属的卤化物在这出元素的化学分析中起着极其重要的作用。

氧化物和氢氧化物:铂族金属的氧化物和氢氧化物在这些元素的化学分析中占有一定位置。铱、锇、钌的氧化物具有很高的挥及性，可以利用此特性与其他金属分离。
    硫酸盐和亚硫酸盐:铂族金属的硫酸盐盐和亚硫酸盐容易水解，在溶液中经常会有不稳定的水合离子，也有稳定的聚合物基化合物以及复杂的多聚水合硫酸盐。
    硫化物:形成金属硫化物是铂族金属的共有特性，在化学分析中占有一定位置，可以通过各种方法制得它们的硫化物，如铂族金属的氯化物溶液中通入硫化氢或用碱金属硫化物作用时可以得到它们相应的硫化物。硫化物的形成被广泛地用来作为铂族金属的沉淀剂，以便从其他贱金属中分离出来。铂族金属硫化物在水中的溶解度减少的顺序排列为IrS8> Rh2Sz > PtS2 > RuzS> OsS, > PdS.在复杂的硝酸溶液中，铱不被作为硫化物形武沉淀，可以利用这一性质从RhP和Pd中分离I.在高温(约3000)下，碱金属硫化物同铂族金風的硫酸盐相互作用，铱和铑两种硫化物已不再被完全沉淀，这就可以从铂中分离铱和铑。渣浆泵厂家
    硝酸盐:铂族金属中只有钯可以直接被硝酸溶解，形成相应的硝酸盐，结晶成为PaONO容易潮解，易容于水硫服化合物:铂族金属都能与硫际或苯基硫睬形成稳定而有成的络合物。在酸性溶液中，或者在加热情况下，硫腺与费金属形成的络合物被分解生成难溶性的硫化物。用该法可使铂族金属利其它贱金属分离。

此外，铂族金属同氨能形成稳定的络合物。

Important compounds of platinum group metals in pump industry

Halide: all finely powdered platinum group metals react with chlorine when heated to form volatile halides under certain conditions. Halides of platinum group metals play an important role in the chemical analysis of this element.

Oxides and hydroxides: oxides and hydroxides of platinum group metals occupy a certain position in the chemical analysis of these elements. The oxides of iridium, osmium and ruthenium have high volatility, which can be used to separate them from other metals.

Sulfates and sulfites: sulfates and sulfites of platinum group metals are easy to hydrolyze. In solution, there are often unstable hydrated ions, stable polymer based compounds and complex polyhydrated sulfates.

Sulfide: the formation of metal sulfide is a common characteristic of platinum group metals, which occupies a certain position in chemical analysis. Their sulfides can be obtained by various methods, such as when hydrogen sulfide is introduced into the chloride solution of platinum group metals or when alkali metal sulfide is used for reaction, their corresponding sulfides can be obtained. Sulfide formation is widely used as a precipitant for platinum group metals to separate from other base metals. The order of the decrease of solubility of PGMS in water is irs8 > rh2sz > PTS2 > ruzs > OSS, > PDs. In complex nitric acid solution, iridium is not precipitated as sulfide, which can be used to separate from RHP and PD. I. at high temperature (about 3000), alkali gold sulfide interacts with sulfate of PGMS, and iridium and rhodium are no longer completely precipitated This allows iridium and rhodium to be separated from platinum.

Nitrate: only palladium in platinum group metals can be directly dissolved by nitric acid to form corresponding nitrate, which is easy to deliquesce when crystallized into paono, and easy to be contained in water sulfur suit compound: platinum group metals can form stable and formed complex with sulfur or phenylsulfur. In acid solution, or under heating, the complex formed by sulfur gland and ferrous metal is decomposed to form insoluble sulfide. The platinum group metals can be separated from other base metals by this method.

In addition, platinum group metals can form stable complexes with ammonia.
