The Solubility Product of Ferrous Sulfide in Solutions of Varying Ionic Strength
… specifically to study the variation of the solubility product of ferrous sulfide in aqueous solutions of potassium nitrate up to a concentration of 1 molar. |Ferrous sulfide was precipitated by bubbling hydrogen sulfide through solutions containing known concentrations of ferric nitrate and …

LANTHANUM-BASED MATERIALS FOR NUTRIENT PHOSPHORUS REMOVAL FROM AQUEOUS SOLUTION: OPTIMIZATION, CHARACTERIZATION AND APPLICATION
… phosphorus scavenger due to their low solubility product. In this thesis, lanthanum was used as the adsorbent and developed into different forms for the phosphorus removal. The lanthanum carbonate in particle form was the most effective and efficient with the highest phosphate …

Computer simulation of carburization corrosion of nickel-base superalloys
… accounts for internal precipitation of corrosion products whenever thermodynamic solubility limits are exceeded. Up to four different carbides can be treated simultaneously. The solubility product is computed for each reaction and the amount of carbon that reacts is removed from the diffusion …

The plastic deformation of alloys based on aluminum titanide
… analytically and determined experimentally. The solubility product for the formation of erbia (Er$\sb2$O$\sb{3)}$ in a Ti matrix has been calculated using known thermodynamic data which allows the concentration terms in the Lifshitz, Slyozov and Wagner coarsening equation to be calculated. …

Increasing fuel cell run time by preventing precipitation of reactants or products in direct sodium borohydride fuel cell
… to manage water flow so as to avoid reaching solubility limits of reactants as well as products, which dominate the fuel cell run time. The model for solubility is built on solubility product and common ion effect theory. Hence, the model not only considers the decrease of water in the …

Admicellar Polymerization Of Calcium Carbonate And Its Performance In Drilling Fluids
… the phase behavior of SDS with calcium ion. The solubility product constants (Ksp) for calcium dodecylsulfate (Ca(DS) 2) were calculated as 1.55x10?9M3 at 30°C and 8.58x10?9M3 at 50°C. At SDS concentrations above the CMC, precipitation of Ca(DS)2 was governed by the critical ratio of calcium ion …

Influence of Water Chemistry Parameters on the Dissolution Rate of the Lead (II) Carbonate Hydrocerussite
… concentrations predicted by PHREEQC using solubility constants from literature for cerussite and hydrocerussite. The geochemical modelling program PHREEQC was used to speciate total dissolved lead equilibrium concentrations under experimental conditions to determine an approximate …

Using simulation and lab validation to develop a MnCO3 Recovery Process using CO2
Manganese (Mn) is a critical metal in the production of lithium-ion battery (LiB) precursors due to its role in improving safety, stability and promoting higher efficiency and faster charging of LiBs. Battery-grade Mn or High Purity Manganese Sulphate Monohydrate (HPMSM, MnSO4·H2O), a key LiB …

Zur molekularen Topologie der Bindung natürlicher und rekombinanter Varianten von Alpha 2 -HS-Glycoprotein-Feturin an Hydroxylapatit
… calcium phosphate precipitation. Considering the solubility product of hydroxyapatite and the maximal amount of AHSG bound calcium, the inhibition cannot be explained by a reduction of the ion product. In fact, the inhibition relies on the adsorption of AHSG on calcium phosphate surfaces. This was …

Crystallization of calcium sulphate during phosphoric acid production : improving filtration through improvement in particle shape and size distribution
The production of phosphoric acid from phosphate mineral rock involves the addition of phosphate rock to a concentrated sulfuric acid solution. The induced reactive crystallization process produces a side product of calcium sulfate hydrates, which become the filter media in the subsequent acid …

Sedimentation on the continental margin off the Orange River and the Namib Desert
… to form gypsum, once the calcium/sulphate solubility product is exceeded. On the Walvis shelf off LUderitz residual glauconite was reworked from older Neogene sediments, particularly on Lllderitz Bank. North of latitude 26°S residual phosphorite pellets were probably formed in Neogene …

Decoloured Bloodmeal Based Bioplastic
… such as proteins. Animal blood is a by-product from meat processing and is rich in protein. It is dried into low value bloodmeal and is used as animal feed or fertiliser. Previous work has shown that bloodmeal can be converted into a thermoplastic using water, urea, sodium dodecyl …

Determining the solubility of haematin and haem-drug complexes at relevant pH in aqueous medium via spectrophotometric titration
… of the drug−ferrihaem complex relies on the solubility of ferrihaem itself, the latter was investigated in this research at pH values approximating those of the parasitic DV, in exclusively aqueous medium. Based on the methodology employed in a previous study, UV– visible spectrophotometric …
