Abstract:
... Calcium phosphate nanoclusters (CPNs) are important for the structure, function, and nutrient density of many dairy products. Phosphorylated amino acids in caseins stabilize calcium phosphate as nanoclusters which are amorphous to X-ray diffraction and exist within casein micelles, and these CPNs play a key role in micelle stability. Addition of calcium to milk results in further calcium phosphate ...

arsenic; equations; ferrihydrite; models; pH; sorption; spectral analysis
Abstract:
... Sorption by ferrihydrite is an important control on As(V) concentrations in many oxic aquatic systems. There are significant discrepancies in reported sorption constants (log(KAₛ)), which presents a problem for quantifying and understanding this important system. A review of reported ferrihydrite–As(V) sorption studies indicated a positive correlation between reaction time used in the experiments ...
