Groups. However, some reports have been published on the chiral resolution of nonaromatic racemates on polysaccharide CSPs . As in the case of other CSPs, polysaccharide CSPs do not require a certain combination of functional groups. Therefore, only one group can afford a satisfactory separation. Presumably some chiral space such a concave arrangement or a ravine existing in a polysaccharide derivative may permit such a separation . It is not easy to determine the differences among the structural selectivities of all derivatives.

Many xenobiotics and pollutants are chiral in nature and two enantiomers may have different toxicities . Sometimes, degradation of some achiral pollutants results in chiral toxic metabolites. Therefore, to predict the exact toxicities of pollutants, the concentrations of both enantiomers are required. For example, the two enantiomers of a-hexachlorocyclohexane pesticide have different toxicities. Moreover, the rates of degradation of the enantiomers of a-hexachlorocyclohexane are also different [11, 12].
