Development of Size of Humic Particles in Aqueous Solutions
Original language description
The role of size, conformation, molecular weight and aggregation process of HA as an important parameter for modelling of the reactivity and possible future applications of humic acids. The progress in this area is often limited by huge heterogeneity ofhumic samples. This contribution is dealing with deeper study of behaviour of humic acids in aqueous solutions. Two ways of preparation of humic solutions were used for purposes of this work. Humic acids were dissolved in 0.5 M NaOH solution according tothe IHSS method. In the second way of preparation of humic solutions were humic acids dissolved in water followed by alkalization of the samples to pH value of 12. The samples were characterized by means of dynamic light scattering for determination ofsize of the particles and electrophoretic light scattering for determination of the stability of samples.
