Abstract

Dextran has been determined in sugar juices from beet sugar refining processes by differential‐pulse cathodic stripping voltammetry (DPCSV) at the hanging mercury drop electrode (HMDE). Measurements were performed on diluted samples without previous treatment. The optimised procedure allowed the direct determination of dextran at the mg‐kg^‐1 level. The performance of the procedure is compared with the Roberts copper method.
