Abstract
We report an investigation of dynamic light scattering (DLS) from humi c acid, an organic colloidal fractal system in aqueous solution. The s ystem is found to be power-law-polydisperse in size and the DLS spectr a show the arithmetic and harmonic mean relaxation rates to be a fract ional power of momentum transfer. This behavior is described by the dy namic scaling theory developed by Martin, Leyvraz, and Ackerson.
