摘要：

Chlorophyll a (Chl a) aggregation in alcohol was examined as a function of the type of alcohol, Chl a concentration and water content. The sample preparation procedure was observed to play an important role in determining whether the dihydrate dimer or the monohydrate dimer was formed. The characterization of the different species formed in alcohol on addition of water was carried out using absorption, fluorescence and circular dichroism spectroscopic techniques. The results were confirmed by adsorptive stripping cathodic voltammetry and differential pulse polarography.
