“…36 It is worth mentioning that the SM hydrogel we prepared was more likely to induce M1 polarization of macrophages. This phenomenon was similar to the previous research, 37,38 probably ascribing to the lack of purification of SA, given that it has been reported that the effect of SA on macrophage activity differs depending on the degree of purification, the M/G ratio, and viscosity. 39,40 Our study indicated that loading HM may be a powerful method for regulating the macrophage response in SM-based hydrogels.…”

“…Practice poses well-known requirements to sorbents, first of all, to low cost of their fabrication, to certain parameters of porous structure and to good cations exchange properties. For example, natural silicates after simple modification are the most popular materials used in numerous industrial applications and medicine [21,22] due to high capacity towards radionuclides and heavy metals [23][24][25]. The main advantage of synthetic materials including silicates is the possibility to control the textural and surface properties by correlation of synthetic conditions on the stage of mixing reagents and drying precursors [26,27].…”

In the present study three novel inorganic ion exchange materials on the base of magnesium silicates were synthesized by precipitation and hydrothermal sol gel methods with two reagents ratio. Physico-chemical properties of samples were characterized by thermogravemetric and differential thermal analyses, low temperature adsorption/desorption method and transmission electron microscopic studies. It was found that all sorbents were obtained in a form of amorphous layer-structure magnesium silicates with micro- and mesoporous structure. The ion exchange properties of these materials for Cs+, Sr2+ Cu2+, Co2+and Cd2+ removing from water solution investigated. Data obtained showed that magnesium silicates had the higher capacity toward the heavy metal cations compared to the radionuclides regardless the method used for synthesis. The sample synthesized with excess of metasilicate exhibited the higher efficiency of heavy metal cations sorption than the sample obtained using equimolar ratio of components. Amongst Langmuir and Freundlich models, Langmuir model fitted well for experimental data received on these adsorbents.
