Dissolution effectiveness

Multicomponent dissolution effects have been historically underappreciated, but these phenomena are finally getting some scrutiny. Multi-component effects are likely to influence in vivo-in vitro correlations.

The strong dissolution effects on heavy metals of increasing phosphate concentrations in river water (Fig. 8-19) indicate the strong remobilization effects which result from complex formation. This tendency for complex formation with triphosphates is also described in the literature [GMELIN, 1965]. Increasing the concentration of phosphate in water from 0.38 to 0.68 mg L 1 increases the iron concentration by 648 pg L 1 in water in contact with sediment in which the iron concentration is 16220 mg kg ...

These results indicate that the phase changes to octahydrate from the dodecahy-drate and corresponding dissolution effects could not account for the SINNMR effect because of the much greater signal/noise ratios and a smaller FWHM found in the SINNMR experiment. 

The average 5 value of this study for early calcite (-1.6%o Fig. 19) indicates dissolution of marine carbonate as the predominant source. In Avalon/ Ben Nevis Sandstone the average is close to zero (-0.9%o pdb Hutcheon etal., 1985) (Fig. 19), showing that this source could have provided the carbonate almost exclusively, in line with the abundant dissolution effects seen in the shallow-marine carbonate fossil fragments of the sandstones.

Semi-quantitative XPS analyses on the calcium phosphate deposits revealed that due to the inhibition and dissolution effects of citric acid, the calcium phosphates have Ca/P molar ratios between 0.5 and 1.2. These values are lower than the Ca/P molar ratios for the deposits formed on PHEMA containing no...
