Berthod et al. [325] employed countercurrent chromatography with diethyl-hexyl phosphoric acid (DEHPA) reverse micelles in heptane as a stationary phase to extract metaUic cations such as Fa +, Ce, Pr, and Nd + (lanthanide series). This technique was suggested for the application of ion filtering and concentration or for deionization of aqueous phases. Ashrafizadeh et al. [326] re-... 

The characteristics of the water pool of reverse micelles has been explored by H, 23Na, 13C, 3IP-NMR spectroscopy. Since the initial association process in RMs is not totally understood, and because of the low CMC, aggregation studies from NMR are rather scarce. Direct determination of a CMC in the diethyl hexyl phosphate /water/benzene system (at Wo = 3.5) was possible because the chemical shift of 31P in phosphate groups is very sensitive to hydration effects. The structure and state of water in RMs and particularly at low water content has received considerable attention. The proton chemical shifts have been explored in AOT/water/heptane, methanol, chloroform, isooctane and cyclohexanone. The water behavior in small reverse micelles is close to that of the corresponding bulk ionic solution. Until now, the effect of a solute on micellar structure was not well...

Complexation can be used to separate metallic ions on an industrial scale. Figure 1 illustrates the process in the case of the separation of nickel and cobalt ions [3]. A complexing agent (e.g., diethyl hexyl phosphoric acid) is added to a heptane stationary phase. A large volume (up to 20 times the CCC machine volume Vc)... 

Fig. 1 Removal and separation of cobalt and nickel ions by CCC. Stationary phase heptane + diethyl hexyl phosphoric acid (HA 0.5M) mobile phase aqueous solution of cobalt and nickel acetate (O.OIM each). Step 1 The CCC machine is equilibrated with water. Step 2 The ionic solution is introduced in the machine, the ions are extracted into the stationary phase, and the cobalt complex displaces the nickel one less stable.

In some cases a single surfactant may be sufficient for lowering y far enough for microemulsion formation to become possible examples include Aerosol OT (sodium diethyl hexyl sulphosuccinate) and many nonionic surfactants.

Fig. 2 Removal and separation of cobalt and nickel ions by CCC. Stationary phase heptane + diethyl hexyl phosphoric acid (noted HA, concentration 0.5 Af) mobile phase aqueous solution of cobalt and nickel acetate (0.01 M each). Step 1 The CCC machine is equilibrated with water. Step 2 The ionic solution is introduced into the machine the ions are extracted into the stationary phase and the cobalt complex displaces the nickel one, which is less stable. Deionized water at pH 3 exits the column because all ions are replaced by protons. Step 3 The stationary phase is samrated in nickel ions. The greenish effluent leaving the machine contains only nickel ions, which is 2 times more concentrated than the entering solution. Cobalt ions are still extracted, displacing nickel ions. Step 4 End of the process— the stationary phase is saturated in cobalt ions. The machine is stopped the dark blue stationary phase is collected and cobalt ions are recovered by an add wash.

Complexation can be used to separate metallic ions on an industrial scale. Fig. 2 illustrates the process in the case of the separation of nickel and cobalt ions. A chelating agent (e.g., diethyl hexyl phosphoric acid) is added to a heptane stationary phase. A large volume (up to 20 times the CCC machine volume Vc) of the ionic solution is introduced into the CCC column. The nickel ions are displaced in the aqueous phase, and the cobalt ions can be collected in the stationary phase. More than two ions can be separated in bands of increasing complexation constants order. Because no ions can stay trapped inside the CCC machine, it could be a very potent tool in the separation of radionuclides in the processing of nuclear wastes. 

Phthalates account for 92% of all plasticizers and European production is running at about a million tonnes a year and growing at 3.7% a year. The breakdown of use of different types is diethyl hexyl phthalate (DEHP), 51% diisodecyl phthalate (DIDP), 21% diisononyl phthalate (DINP), 11% and others, 17%.
