Investigation of humic acid samples from different sources by photon correlation spectroscopy
Photon correlation spectroscopy (dynamic light scattering) indicated that relatively large scatterers (50–200 nm diameter) are present in a number of soil, lake and groundwater humic and fulvic acids, as well as in natural waters of high humic content, but absent in ‘synthetic’ humic acid. The influ...

| Zusammenfassung: | Photon correlation spectroscopy (dynamic light scattering) indicated that relatively large scatterers (50–200 nm diameter) are present in a number of soil, lake and groundwater humic and fulvic acids, as well as in natural waters of high humic content, but absent in ‘synthetic’ humic acid. The influence of ionic strength, Ca(II), La(III), EDTA, fluoride ions, surfactants, and ultrasound on size and zeta potential of these scatterers has also been investigated. |
