ABSTRACTThe modelling of the aggregation kinetics of iron oxides has been succesful in predicting the increase in aggregate size as determined by dynamic light scattering measurements. The aggregates were found to exhibit fractal behaviour with fractal dimensions obtained from the scattering exponent in static light scattering studies dependent on the aggregation mechanism and ranging from 2.3 for rapid (diffusion limited) to 2.8 for slow (reaction limited) aggregation. Polydispersity and restructuring of aggregates were found not to affect the relationship between scattering exponent and aggregate fractal dimension. Excellent correspondence over a range of temperatures and ionic strengths has been obtained between results of sizing experiments using dynamic light scattering and sizes predicted using a modified Smoluchowski model incorporating fractal dimensions.

A kinetic study for the phosphorus release of a formulated CaHAP-Z fertilizer was done to observe its behavior when applied to clay loam soil. The study of release kinetics of CaHAP-Z was done along with CaHAP and the control fertilizer Solophos™ to determine whether the formulated fertilizer can be an alternative for the conventional fertilizer. Results showed that the formulated fertilizer CAHAP-Z contains 3.73% phosphorus with 513.10 nm particle (Dynamic Light Scattering) indicating that the formulated fertilizer can be classified as a nanofertilizer. The formulated CaHAP-Z fertilizer showed the slowest release kinetics compared to the controls. In addition, this study showed that the simple Elovich kinetic model is the general equation that best fits to describe the phosphorus release of fertilizers.
