Polyoxometalates in the hofmeister series
WebAug 1, 2024 · Hofmeister effects of ions in aqueous solution strongly affect chemical and biological systems. High and low charge density anions, such as SO 4 2-and SCN-respectively, decrease (salting-out) or increase (salting-in) the solubility of organic solutes in water. Due to their very low charge-density, nanometric anions, e.g. polyoxometalates … WebRanking of Keggin- and Dawson-type polyoxometalates in the Hofmeister series according to their ability to adsorb on polar neutral surfaces Thomas Buchecker,a Philipp Schmid,a …
