The paper deals with a study of interactions of protons in crystallization water of paramagnetic hydrates FeSO4.n H2O (wheren=1, 4, 5 and 7). The interaction of protons and paramagnetic ions Fe2+ and the nuclear dipole-dipole interaction of protons have been studied by means of the ...
How Water of Crystallization Forms Many compounds are purified by crystallization from an aqueous solution. The crystal excludes many contaminants, however, water can fit within the crystalline lattice without being chemically bonded to the cation of the compound. Applying heat can drive off this water...
e.g., MnO/MnSO4, FeO/FeSO4, and CoO/CoSO4[4], the sulphates is not popular due to the demand for the gaseous products separation of SO2and O2. A large number of metal oxides have been proposed for thermochemical
crystallization waterTG-DTG-DTAkineticsThe nature of the crystallization water in some hydrates with different cations, namely: MnSO4·H2O; FeSO4·7H2O; CoSO4·7H2O; NiSO4·7H2O, has been studied by the application of the following non-isothermal techniques: thermogravimetry (TG), derivative ...
Was subjected to hydrolysis by adding ammonia, after 20 minutes the solution was warmed to maintain 80 ℃ crystallization using an applied magnetic field separated Fe3O4 magnetic nanoparticles obtained by the reaction. 将制得的Fe3O4纳米颗粒用去离子水稀释,用氨水调节pH=8,加入AgNO3,搅拌均匀,加入没...

Radiolytic Hydrogen Formation in Transition Metal Sulphate Crystals Containing Water of CrystallizationThe G-values for H2 are measured for MnS04. 5 H2O, FeSO4 7 H2O, cosO4. 7 H2O, NiSO4. 7 H2O, ZnS04. 7 H2O, MgS04. 7 H2O and 3 CdS04. 8 H2O. Also the hydrogen yields are measured...
(III) are minor and present as FeSO4+, Fe(SO4)2−, and FeHSO42+. Under circumneutral pH in the study area, hydroxide species such as Fe(OH)2+and Fe(OH)4−are dominant. Mn is present either as free aqueous ions or as sulfate and bicarbonate species. Saturation indices show that...
The influence of feed water pretreatment carried out in a contact clarifier (softening with Ca(OH)2 and coagulation with FeSO4 路 7H2O) followed by filtration, on the process effectiveness was evaluated. It was found that the chemical pretreatment decreased the membrane fouling; however, the ...
