Association of Humic Substances: Verification of Lambert‐Beer Law |

| Authors: | H Langhals G Abbt‐Braun F H Frimmel |
| Abstract: | The precision UV/Vis‐absorption spectra of a naturally occurring aquatic humic substance were measured in the range of concentration 0.003 to 1.4 g/L DOC (dissolved organic carbon). Lambert‐Beer law is well obeyed at low concentrations whereas deviations have been observed for DOC concentrations above 0.1 g/L: they are interpreted in terms of self‐solvation and formation of micelles. |
