Second, the calcium-binding properties of several inhibitors such as poly-L-aspartate, poly-L-glutamate, and alginates were analyzed by the Langmuir equation. They were well-described by the Langmuir equation. The tested inhibitors were classified into two groups: inhibitors of which parameters ...
The sample was pre-immersed in PBS for 1 day and weighed (Wsat), then the sample was taken out every other day. Excess water was slightly wiped from the surface, and residual weight (Wresidual) of each sample was measured until the sample was completely degraded. The equation for calculati...
current understanding of mineral solubility predicts negligible phosphate concentrations for most natural waters, yet the role of Fe2+, ubiquitous on early Earth, is poorly quantified. Here we determine the solubility of Fe
Activity coefficients were determined by the Debye-Huckel equation. The presence of CO2(g) at 2 × 10−2 bar (2 kPa) and an ionic strength standardized by 0.01 M NaNO3. Calcium concentrations were 0.001 mol/L. Within a pH column, ( ) indicates...
Under the guidance of teachers by students to write a chemical equation, and points out that laboratory available solid ammonium chloride and hydrated lime for preparing ammonia. (NH4) 2SO4+Ca (OH) 2=CaSO4+2H2O+2NH3 = 2NH4Cl+Ca (OH = 2=CaCl2+2H2O+2NH3) Writing: This is containing ...
A binary equation model was then established to obtain the temperature and oxygen concentration information. The experimental results demonstrate that quantitative two-dimensional sensing of oxygen concentrations in high-temperature environments can be achieved using the current method with only UV light and...
By reversing the matrices of each chemical shift from the active metabolites, a functional relationship among each concentration of the 52 active metabolites, pH plus T and the 1H NMR chemical shifts of the active metabolites is accomplished and the following equation is derived: ...
Different sizes of cylindrical pellets of two types of fertilizers, namely; calcium dihydrogen phosphate (Ca (H(2)PO(4))(2)) and ammonium sulfate ((NH(4))(2)SO(4)) of typical compositions were coated with layers of CaCO(3) consisting of different proportions of nano-CaCO(3) of 0%,...
Based on the literature, alkaline conditions produce both positive and negative effects due to the changes in electrochemistry, with other surfactants (depressant, collector) bringing their own contributions to the equation also. Majority of these effects are most likely also realized when the alkaline...
