An Analytical Investigation of the Behavior of E260 Absorbant Substances by Gel Chromatography.

E260 absorbant substances constitute a major fraction of dissolved COD in natural water. And the investigation of the behavior of E260 absorbant substances is essential for the control of COD in Lake Kojima.The movement and variation of molecular weight fractions of E260 absorbant substances were evaluated by the gel chromatography.By using gel chromatograms of waters prepared in various mixing ratios of distilled water and pond bottom soil, it was clear that E260 absorbant substances moved for keeping the adsorption equilibrium between water and soil.E260 absorbant substances in the soil showed that higher molecular fraction decreased in aerobic state and lower molecular fraction decreased in anaerobic state.The components of lower molecular fraction of E260 absorbant substances in domestic effluent decreased through the flowing down process in February. And it was suggested that the decrease of components was affected by anaerobic bottom soil.
