Abstract:

A sequential gel filtration chromatography coupled with UV detector was applied for the characterization of molecular size distribution of aquatic humic substances.The working range of the system using Sephadex G-25 and G-100 covers almost the whole range of the molecular size distribution of aquatic humic substances.The system was calibrated using standard proteins and a discontinuous function can fit the calibration curve well.
