Here, we determine the solubility of dolomite [CaMg(CO3)2] and rhodochrosite (MnCO3), and put an upper limit on that of magnesite (MgCO3) in highP–TH2O–NaCl fluids. We combine these with available data on calcite/aragonite28,29,30, smithsonite (ZnCO3)40, and strontianite (SrCO3)41...
The upper limit depicted on the solutus curve by both CaCO3 and NiCO3 saturation curves can also be described by considering that the pure endmember will invariably possess larger free energy compared to the solid containing a non-zero proportion of substitutional impurity [34]. In addition, ...
Phytase activities in non-phytase Trt were all below the detection limit of the assay, demonstrating no cross-contamination between phytase and non-phytase Trt during mixing. Analyzed phytase activities in phytase Trt were close to formulated within 10% of formulated values (Table 3). The 3 ...
Amendment of litter with either FeSO4 .7H2O or alum resulted in the lowest soluble reactive P levels after 294 days. Use of chemical amendments to limit P solubility has potential and should be pursued as a means of reducing eutrophication of sensitive surface waters where poultry litter is ...
Solubility is a physical property that describes the integration of a solute with a solvent, making a homogenous (uniform) mixture of the two substances. Each substance has its solubility limit, varying from extremely small to extremely large. For example, sodium chlori...
Sequential fractionation data suggested that Ca–Mg-associated P accounted for a dominant proportion of total P in farmed soils, but this fraction was below the detectable limit in unfarmed soils. These findings demonstrate that the repeated heavy application of phosphate fertilizer during many years ...
The ionic strengths (<0.01433 mol/L) were within the valid limit for the extended Debye–Hückel equations. 3. Results and Discussion 3.1. Solid Characterization 3.1.1. Composition The Cd/(Ca+Cd) mole ratio (XCd) of the synthetical calcite–otavite solid solution, which was calculated for ...
