黄钾铁矾

国内外湿法冶金中常采用黄钾铁矾法或针铁矿法等方法除铁，硫化沉淀法分步沉淀或较高pH条件下萃取分离镍、钴，不适用于常温、较低pH的生物浸出液。

Iron was precipitated by the formation of jarosite or goethite . And sulfide precipitation or extraction of nickel and cobalt at high pH were used in the hydrometallurgy at home and abroad .

当溶液中Fe3+浓度达到一定程度的时候形成黄钾铁矾沉淀，而溶液的pH值会先变大后变小，维持在2.0～2.5之间。

When ferric iron concentration was high enough in the solution , jarosite was produced . In this process , the pH value of the solution became larger firstly , and then smaller , and always maintains in the range of 2.0 ~ 2.5 .

并对固定床生物反应器运行中在载体表面形成的络合物进行了研究，X射线衍射证明此络合物为黄钾铁矾[KFe3（SO4）2（OH）6]。

The complex compound formed on the surface of the carriers during operation has been studied and by X-ray diffraction analysis it was proved to be jarosite .

将该溶液用黄钾铁矾法除去溶液中的铁，经KMnO4和（NH4）2S2O8除Mn，沉淀得纯ZnO。

After iron re - moval by Jarosite methode the solution is sent to purify the Mn by KMnO_4 and ( NH_4 ) _2S_2O_8 , then to precipitate pure ZnO .

理论上，在没有生物生命形式的帮助下，形成黄钾铁矾也是有可能的。

Now , theoretically it is possible for jarosite to form without the help of biological life forms .

氟氯也可以形成不溶物给除去，K+、Na+也可以由黄钾铁矾除去铁的同时形成黄钾铁矾渣而排出系统。

F-1 and Cl-1 formed insoluble material can be removed . K + and Na + formed the jarosite slag can be removed while removing ferrous ion .

且由于大多数行星科学家都相信，水是生命之源，有黄钾铁矾说明火星曾具备生命的先决条件。

And since most planetary scientists believe that water is essential to life , the presence of jarosite means that one prerequisite for life was once present on Mars .

分析认为，废液呈强酸性、溶液中存在大量Fe2+、碱金属离子含量偏低是蒸发结晶过程中形成绿钾铁矾而不是黄钾铁矾的主要原因。

The strong acidity , Fe ~ ( 2 + ) and rather lower concentration of alkalis ions are responsible for voltaite , not jarosite , crystallizing from the acidic iron-bearing water .

所以，假如火星上的黄钾铁矾也是在微生物的帮助下形成的，我们也许能在找到的样本中检测到残余物，这不是没有可能的事。

So it 's possible that if the jarosite on Mars was also formed with the help of microorganisms , we might be able to detect remnants of them in the samples we find .
