Care must therefore be taken in designing tests to study the effects of solution composition since different results will be obtained depending on the degree of aeration and/or movement of the solution.

In examining the effect of solution composition on the purity of recovered L-Ile crystals some unusual observations have been noted. Figure 7 shows data similar to that presented in Figure 4 for L-Ile HCMl20 with one major difference L-Valine is relatively unimportant as an impurity in comparison to L-Leu. Even though there is greater scatter in the data than was observed in the acid-addition experiments, purification factors for the two impurities are less than one and nearly constant.

Physical development can occur on nuclei with the simultaneous reduction of silver ion and oxidation of the developing agent. The two partial processes can also be separated in a model cell so that the effect of solution composition on the separate anodic and cathodic parts can be seen (Figure 14). Kawashima et al.

The effects of solution composition (aside from reactant concentrations, pH, and background electrolyte concentrations) on reaction kinetics should also be studied. Using different but chemically related reactants and competitive effects from other species in solution are examples of this approach. For example. Stone and Morgan (1984) examined the effect of different organic compounds on dissolution rates of Mn oxides. 

The effect of solution composition on the BET surface area of ZrO, powder is shown in Table 2. Obviously, with the decrease of the amount of urea or water in the presence of HNO, BET surface area of ZrO, powder increases and the concentration of nitric acid shows a optimum value. This indicates that less urea and water, with moderate nitric acid, are important for higher BET surface area.

Partition coefficients describe not the ion exchange but the distribution of only one of them between the media. It does not accoxmt for the effect of solutions composition and properties. Because of this the partition coefficient is not suitable for evaluating ion exchange. Nevertheless, it may be associated with the selectivity and exchange coefficients. Weight concentrations in equation (2.164) may be expressed through molar or equivalent fractions of exchange capacity and molar concentrations in the solution ...
