The hydrodynamic radii (Rh0) of micellar particles are calculated. The results suggest that Rh0 decrease initially due to collapse of the shear plane toward the micelle hard-sphere surface, and then Rh0 increase gradually due to electrolyte-induced linear spherical expansion of the micellar particles. Based on it, the location of micellar shear plane, the relationship between the shear plane and Debye-Hückel length, and the associated ζ-potential are also estimated. It is found that the relationship between the shear plane and Debye-Hückel length is linear, and, in different NaCl concentrations, the shear plane is almost located at a constant shear potential of 77 ± 10mV, close to the hard-sphere surface of SDS micelle particles. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Yang Zhenyu aut Zhao Jinsheng aut Xie Yu aut Yin Xiuli aut Du Zhankui aut Yang Zhengyu aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/2/2004(2004-02-01), 201-210 0942-9352 218:2/2004<201 2004 218 zpch https://doi.org/10.1524/zpch.218.2.201.25922 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.2.201.25922 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Yang Zhenyu aut NATIONALLICENCE 700 1- Zhao Jinsheng aut NATIONALLICENCE 700 1- Xie Yu aut NATIONALLICENCE 700 1- Yin Xiuli aut NATIONALLICENCE 700 1- Du Zhankui aut NATIONALLICENCE 700 1- Yang Zhengyu aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/2/2004(2004-02-01), 201-210 0942-9352 218:2/2004<201 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
