Sažetak
Light-scattering data of suspended clusters of particles in seawater have been analysed to find some evidence for fractal structure of the scatterers. The behaviour of the scattering intensity I(q) as a function of q suggests that the scattering medium consists of two kinds of particles, large ones, with fractal dimension 1.7 ą0.1, resulting from a regular DLCA growing process, and smaller ones, with a considerably larger fractal dimension 2.7 ą0.4, resulting from a more complex cluster-cluster aggregation process in which low sticking probabilities, restructuring and settling could be present. This conclusion is strongly supported by the I(q) curve which, in a log-log plot, exhibits two well defined linear regions. In interpreting data, it is assumed that the polydispersity of the scatterers is described by a smooth two-component particle-size distribution. The fractal structure of the scatterers is described by the behaviour of the scattering intensity from clusters of different size.
