The separation factor is one distribution ratio divided by another; it is a measure of the ability of the system to separate two solutes. For instance, if the distribution ratio for nickel (D Ni) is 10 and the distribution ratio for silver (D Ag) is 100, then the silver/nickel separation factor (SF Ag/Ni) is equal to D Ag /D Ni = SF Ag/Ni = 10.
