WebApr 12, 2024 · 1 Introduction. It has been demonstrated that specific ion effects are universal in aqueous, 1, 2 nonaqueous, 3 and interface systems, 4-8 and show a reoccurring trend called the Hofmeister series, which is normally more remarkable for anions than for cations. It can be divided into anionic and cationic series and ranked by their abilities of … WebWe propose a simple experimental procedure based on the cloud point measurement of a non-ionic surfactant as a tool for (i) estimating the super-chaotropic behaviour of …
Web2 days ago · In fact, Hofmeister effects in colloidal systems are strongly governed by the microscopic water structure around both the particle surface and the solvated ions. When the surface turns from hydrophobic to hydrophilic, an inversion of the Hofmeister series occurs [19], [70], [71].
