Sodium chloride nitrate system, values

Table VIII. Values of A and B in Equation 2 for Sodium Chloride (1)—Magnesium Sulfate (2)—Potassium Nitrate (3) Mixed-Salt System...

Sato etal. [238] studied the mechanism of formation of silver halide particles grown from reverse microemulsions. In a typical process, aqueous solutions of either (a) silver nitrate or (b) a sodium salt, i.e. sodium chloride, bromide or iodide was injected into AOT/isooctane reverse micelles. When equal volumes of the two kinds of microemulsion were rapidly mixed at 25°C, particles started forming. The particle diameter was a function of the type of the anion, the w value as also reaction time. For AgBr, the maximum diameter was - 2.7 nm for Agl, it went up to 5.5 nm. Bagwe and Khilar [444] synthesized AgCl nanoparticles from AOT/ alkane (cyclohexane, heptane, decane) systems. The aqueous phases were solutions of silver nitrate or alkali/alkaline earth halides. The number average particle size was in the range of 4-10 nm.
