Chih M.-H.Lee E.Chu J.-W.Hsu J.-P.2019-05-152019-05-15200007437463https://scholars.lib.ntu.edu.tw/handle/123456789/408532The sedimentation of concentrated charged spherical particles in an electrolyte solution is investigated theoretically for an arbitrarily thick double layer taking the effect of double-layer polarization into account. We show that the ratio E*/U* (=scaled sedimentation potential per scaled sedimentation velocity) is a constant if £ea is either very small or very large, £e and a being respectively the reciprocal Debye length and the radius of a particle. The variation of E*/U* as a function of £ea has a minimum at a medium £ea. This minimum increases with the increase in particle concentration. The scaled sedimentation velocity approaches a constant if £ea is small, and its variation as a function of £e£\ has a maximum at a medium £ea. This maximum decreases with the decrease in particle concentration.[SDGs]SDG14journal article10.1021/la99089922-s2.0-0033873674https://www.scopus.com/inward/record.uri?eid=2-s2.0-0033873674&doi=10.1021%2fla9908992&partnerID=40&md5=dab1c4cfa07cbc996faee183d9bc1289
