An approximate analytic expression for the surface charge density/surface potential relationship (/ 0 ) for a spherical colloidal particle in a solution of mixed and nonsymmetrical electrolytes is obtained by solving a nonlinear Poisson-Boltzmann equation using a linearization approximation.

An approximate analytic expression for the electrophoretic mobility of a spherical colloidal particle in a symmetrical electrolyte solution is obtained. This mobility expression, which is correct to the order of the third power of the ζ-potential of the particle, considerably improves Henry's mobili
The equations developed by C. S. Mangelsdorf and L. R. White (J. Chem. Soc. Faraday Trans. 88, 3567 (1992)) to calculate the electrophoretic mobility of a solid, spherical colloidal particle subjected to an oscillating electric field are solved analytically for low zeta potential, \(\zeta\), to obta
## Abstract In this study, the CD derivative, mono (6^A^‐azido‐6^A^‐deoxy)‐__per__(__p__‐chlorophenylcarbamonylated) β‐CD was chemically immobilized onto the surface of an amino‐functionalized silica gel with different pore (100, 300, and 500Å) and particle (3, 5, and 10 μm) sizes to obtain novel c
