چکیده
In the crystal structure of the title compound, 2C(2)H(7)N(2) (+)·SO(4) (2-), which contains four cations and two anions in the asymmetric unit, the ions are inter-connected by an extensive hydrogen-bonding system whereby two of the O atoms of sulfate ion are hydrogen-bonded to the amidinium H atoms of two cations, leading to the formation of two eight-membered rings. The two remaining O atoms inter-connect two H atoms of acetamidinium cations, forming an infinite chain. The C⋯N separations within the H(2)N⋯C⋯NH(2) moieties are similar, with an average value of 1.305 (2) Å, which is in good agreement with a delocalization model.

Electrochemical Sulfate Removal from Aqueous Solution Using Sandwich Panel Carbon Cloth Electrode by Steel Mesh: A laboratory study
Background and Objectives: Sulfate is one of the chemical pollutants in water that can cause adverse health effects such as digestive and blood problems at high concentrations in humans. Conversion of sulfate to substances such as hydrogen sulfide can corrode metal pipes. Therefore, the aim of this study was to investigate the effect of electrochemical sulfate removal using a sandwich panel car...
متن کاملSynthesis of Zinc-Sulfate Nano Particles and Detection of Their Induction Time, Nucleation Rate and Interfacial Tension
The production of zinc sulfate is important both medically and agriculturally. If zinc sulfate is produced without agglomeration at the nanoscale, its absorption in the body is more and faster. In this research, the induction time parameter is assessed for nucleation of zinc sulfate nanoparticles at room temperature and various supersaturations using acetone (as anti-solve...

Aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (Al(NO3)3.9H2O) and ammonium sulfate ((NH4)2SO4). The resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal decomposition of aluminum sulfate. The crystallinity and phase of the as-synthesized and calcined samples were char...
