Reinforced silica monoliths functionalised with metal hexacyanoferrates for cesium decontamination: a combination of a one-pot procedure and skeleton calcination

Abstract

Procedure describes the synthesis of silica monoliths functionalised with metal hexacyanoferrate (MHCF) using a high internal phase emulsion template. The materials exhibit excellent Cs ion sorption properties.

Searching for the nano effect in Cu-HCF (II) particles to improve Cs sorption efficiency: Highlighting the use of intrinsic magnetism

“…These templates can range from soft polymers to hard inorganic materials such as silica microspheres, or highly ordered silica monoliths. [6,[8][9][10][11] By employing template chemistry the particles are separated and dispersed throughout a porous template material thereby allowing for greater access to their surfaces. However, for financial reasons industrial setups are slow to adapt to new technologies and in fact aggregated HCFs are still used today to extract Cs from waste pools using physical aggregation to disperse the HCF in the effluent, and solid/liquid separation techniques to remove it once Cs has been extracted.…”

Breakthrough studies of the adsorption of Cs from freshwater using a mesoporous silica material containing ferrocyanide

“…One way to overcome these drawbacks is to insert selective ferrocyanide (hexacyanoferrate) nanoparticles in a solid porous matrix to make it amenable to column processes: the porosity of the support and the high surface/volume ratio of the hexacyanoferrate particles inside the pores improves the adsorption rate. Numerous composite solids (organic or inorganic) loaded with hexacyanoferrate particles have thus been proposed for cesium removal in the past few years [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”
