Abstract
A simple column method employing Amberlite XAD-1 (60–120 mesh) resin for the simultaneous extraction of coprostanol and algal chlorophyll a was proposed and evaluated. The results showed that the efficiencies of the column extraction for these two water quality indicators were comparable to or better than the conventional hexane liquid/liquid partitioning and aqueous acetone extraction for the respective compounds. Furthermore, the column technique was time-saving and more economical.
