2024年1月1日 · NH 4+ and SO 42− rich wastewater can be treated in a sustainable way by Bacillus cereus granules. In this study, an exploratory experiment conducted to assess the efficiency of time reducing Bacillus cereus FDAARGOS_798 strain in the Sulfate-reducing anaerobic ammonium oxidation –Sulfammox- process at lab-scale reactor.

磷酸铁锂（LFP）正极材料生产过程中产生大量含铵盐废水，主要为NH 4 H 2 PO 4 和 (NH 4 ) 2 SO 4 。 然而，作为盐分离的重要基础，这两种盐的固液相平衡（SLPE）很少有研究进行研究。 本研究采用等温溶解法研究了三元体系（NH 4 + //SO 4 2− , H 2 PO 4 − –H 2 O）在101.2 kPa下从313.15 K到343.15 K的SLPE，并研究了相应的物理化学性质。 测量饱和溶液的性质（密度、粘度和pH）。 NH 4 H 2 PO 4 和 (NH 4 ) 2 SO 4 的相图由1个不变点、2条单变量曲线和2个单盐 …

2023年10月1日 · In this work we have reported for the first time the influence of ammonium sulphate [ (NH 4) 2 SO 4] on the solubility and related transfer thermodynamics for better understanding of solvation characteristics of l -Proline in electrolytic solvent systems.

This study presents ISORROPIA II, a thermodynamic equilibrium model for the K + –Ca 2+ –Mg 2+ –NH 4+ –Na + –SO 42− –NO 3− –Cl − –H 2 O aerosol system.

2024年10月1日 · In this study, the inhibition of SO 42- and NH 4+ on vanadium extraction from the high-calcium shale during the internal recycling of vanadium industrial wastewater (the raffinate and the precipitated liquor) was investigated and a novel approach was proposed to eliminate the negative effects.

2021年8月6日 · 首先Fe3+具有离谱的水解（见下图），这意味着要想得到“正宗”的Fe3+，溶液必须显强酸性。但是因为H2SO4的pKa2比较大（1.99），强酸性条件下存在的SO4 2-很少。

Ammonium Sulfate | (NH4)2SO4 or H8N2O4S | CID 6097028 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

Equilibria data for the Na+,NH4+∥SO42–,Cl––H2O quaternary system at (10, 20, 30, 50, 90, and 100) °C were measured, and the phase diagrams at (10, 50, and 100) °C were constructed. Furthermore, the crystallization zones in the phase diagrams are discussed in detail.

2023年4月19日 · The solubilities of the ternary system MgSO4– (NH4)2SO4–H2O and the quaternary system Na2SO4–MgSO4– (NH4)2SO4–H2O at 0 °C were measured, and the phase diagrams of these two systems were plotted. On the… A new separation technique, called stripping crystallization (SC), is applied here in the purification of the cresol isomer.

NH4 + SO4 = (NH4)2SO4 is a Synthesis reaction where two moles of Metallic Ammonium [NH 4] and one mole of Sulfur Tetroxide [SO 4] combine to form one mole of Ammonium Sulfate [(NH 4) 2 SO 4]
