| 520 | 3 |a"The photodegradation of the dyestuff Disperse Blue 26 has been studied in sunlight and under 300 nm light in organic-free water and in natural waters. Dissolved humic acid has been demonstrated to promote the photodecomposition of the dye. The results indicate that the half-life of sunlight degradation of the dye in near-surface waters will be of the order of a few days in summer to a few weeks in winter. Moreover, photolysis will be retarded at depths greater than a few decimetres to two metres, and may be retarded by the predicted slight tendency of Disperse Blue 26 to partition to sediment"--Abstract. |
