Abstract: In this study, the effects of adsorbed fulvic acid, a naturally occurring organic acid, on the kinetics of hematite aggregation and on the resulting structure of hematite aggregates are investigated. A model based on colloid stability theory which also accounts for the structure of the aggregates formed is used to describe the aggregation kinetics of these adsorbed particles. The study of aggregate structure shows that the fractal dimensions of hematite aggregates which are partially acid molecules are higher than those obtained with no adsorbed fulvic acid The scattering exponents obtained from static light scattering experiments of these aggregates range from 2.83 +- to 3.42 +- 0.1.
