This CA change could be due to the simultaneous presence of ionic calcium species and calcium sulphates that precipitated as gypsum. The XPS data show Cu presence on the sphalerite surface after copper activation in the salt solutions was in the Cu(I) state. The effect of Ca(NO3)2, Mg(...
The obtained filtrate is dried at 50-55 °C to obtain magnesium sulphate. The mother liquor is returned for ingredient use. Recrystallization: the bitter brine obtained in the salt lake is subject to natural evaporation to be condensed into crude magnesium (crude magnesium sulfate). The crude ...
Many studies have confirmed the important roles of nutritional status and micronutrients in the COVID-19 pandemic. Magnesium is a vital essential trace element that is involved in oxidative stress, inflammation, and many other immunological functions and has been shown to be associated with the outco...
degradation solution were also tested by atomic absorption spectroscopy (VARIAN, SpectrAA 220FS/220Z). At each test time point, the samples were taken out and dried at 60 °C for 24 h to calculate the weight loss ratio. The weight loss ratio was calculated according to the Equation (1) ...

With increasing x, the sulphate activity coefficient steadily falls, the copper(II) and magnesium activity coefficients go through a minimum near x=1, and the standard rates fall. The kinetic changes with x reveal some information on double-layer and ligand effects....
Mixing of copper sulphate into Magnesium Oxysulfate Cement results in remarkable increase in strength and water tightness of the cement. Setting periods of the cement have also been increased. Other Properties such as Weathering Effects, Moisture Ingress, Compressive Strength, and Linear Changes have ...
Liquid fertilizers containing magnesium sulfate, urea and copper sulfate are described. Liquid solution-type fertilizers are characterized by high phase stability even when stored long-term at temperatures below freezing point. The products are suitable for non-root foliar application, both for preventive...
