铵矾

The performance of potassium ammonium jarosite for zinc and indium ions adsorption in the sulfate system is investigated.

考察黄钾铵铁矾对硫酸盐体系中锌、铟的吸附性能。

The results indicate that both the precipitates produced by Leptospirillum ferriphium strain DY and Acidirhiobacillus ferrooxidans strain GF are composed of jarosite and ammonium jarosite. However, the content of jarosite in the precipitates synthesized by strain GF is 5.53% higher than that synthesized by strain DY, but the content of ammonium jarosite in the precipitates synthesized by strain DY is 15.24% higher than that synthesized by strain GF.

结果表明：无论是嗜铁钩端螺旋菌DY菌株，还是嗜酸氧化亚铁硫杆菌GF菌株合成的沉淀都是黄钾铁矾和黄铵铁矾的混合物；其中，GF合成的沉淀混合物中黄钾铁矾的含量比DY合成的黄钾铁矾约高出5.53%；而DY合成的沉淀中，黄铵铁矾的含量比GF合成的沉淀中的黄铵铁矾的含量约高出15.24%。

The potassium ammonium jarosite with zinc and indium is obtained by Fe3+ ion removal from the iron,zinc and indium coexisted sulphate system by potassium ammonium jarosite process.

在铁、锌、铟共存的硫酸盐体系中采用黄钾铵铁矾法除铁，得到了含锌、铟的黄钾铵铁矾，通过TG/DTA和XRD对黄钾铵铁矾及其热分解产物进行表征。

The method of reduced ammonia marinate was selected to do the distill experiment of cobalt and of other metallic elements from ocean manganese nodules and the iron in marinated solution was removed with ammoniojarosite and cobalt was separated from other metallic element with method of sulfuration deposition.

选择还原氨浸法对大洋锰结核中的多金属进行了浸取实验，并用铵黄铁矾法对浸取液进行了除铁及用硫化沉淀法对钴进行分离提取等实验。

The method of reduced ammonia marinate can dissolve many kinds of metallic elements from manganese nodule effectively with a maximum cobaltic distill ratio of 93.25%.

氨浸提取可以有效地使金属离子从结核中溶出，其中钴的浸出率最高可达93.25%；铵黄铁矾法可将浸出液中的铁全部去除。
