The method of extracting sulfur by the solvent of ammonium sulfide and atmospheric distillation are chosen for the test after comparison the advantages and disadvantages of different methods of extraction sulfur from sulfur residues and consideration of composition and components of sulfur residues. 通过对各种提硫方法优缺点的比较,综合考虑硫磺渣的组成和成分,分别选取了硫化铵溶硫和常压蒸馏的方法来提取硫磺。
Ammonium tungsten oxide sulfide [ ( NH4) 2WO2S2] crystal was synthesized in aqueous solution using ammonium metatungstate ( AMT) and ammonium sulfide as raw materials. 本工作用偏钨酸铵和硫化铵为原料,在水溶液中合成二硫代钨酸铵晶体[(NH4)2WO2S2]。
Treatment of Ammonium Sulfide Wastewater by Supercritical Water Oxidation 超临界水氧化法处理硫化铵废水
Synthesis, Characterization and Thermal Decomposition Mechanism of Ammonium Tungsten Oxide Sulfide Crystal 二硫代钨酸铵晶体的合成、表征与热分解机理的研究
Study is made of the treatment of acid effluent from ammonium molybdate plant by addition of ammonium sulfide and pH value control with ammonia spirit. 研究了加硫化氨用氨水调节pH值的方法处理钼酸铵生产中的酸性废水。
The sulfate and ammonium in the influent could decrease the removals of sulfide and nitrate. 进水中有硫酸盐和氨氮会降低硫化物和硝酸盐的去除率。
