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