| Abstract |
Agglomeration dynamics of magnetite nanoparticles under magnetic field are investigated by measuring the change of magnetic weight in different sample containers, cuvette and conical tube. The magnetic weight of the sample increases as the magnetite nanoparticles agglomerate by magnetic field. Analysis of the dynamic change of magnetic weight shows stretched exponential behaviors. Dynamics is slower in the conical tube sample than in the cuvette sample. Difference dynamics in different container is attributed to weaker magnetic field to the sample and potential energy steepening in the conical tube. Some kinetic characteristics involved in the agglomeration such as the distribution function of the rate constant and energy barrier are discussed in details. |
